Q. How do my air conditioning works?
The job of your home air conditioner is transfer heat from inside your home to the outside, thereby cooling you and your family. that's why you put your hand over the outside unit while is working and you feel hot air coming strait up that's part of the proses, other part of the proses is blow cooled air thru the vents and how this happen the air is force by a blower motor and it is cooled by blowing it over the indoor panel called an evaporator coil. and this air is filter by your house air filter that's why is so important maintain and replace your air filter often.
Q. Why is a Heat Pump a Good Idea?
If you're looking for ways to cut your heating electric bill during winter, consider a heat pump system it will cut about half of your home energy use. Also, the easiest way to take a bite out of that part of your bill is with an energy-efficient heat pump. A heat pump is the most efficient heating machine on the market for those home owner that only have electricity on there homes . For every dollar of electricity you put into a heat pump, you get back $2 to $4 of heat. That's energy efficiency! Plus, a heat pump also acts as a central air conditioner in summer, giving you year-round comfort.
Q. How much do heat pumps really save?
That depends of level of efficiency you choose , of course, but if your house is all electric and you are using an electric furnace, you should be able to save between 20% to 30% on your heating costs. however by having install a heat pump system you would have the comfort of air conditioning during summer months too because heat pump system coming with both.
Q. How does a heat pump work?
Instead of making heat, a heat pump extracts it from the outside. Your refrigerator is a good example of a one-way heat pump. It removes heat from the air inside the refrigerator and moves it to the coils on the outside (back or bottom) of the refrigerator. Have you ever felt the warm air that blows out from under your refrigerator when it's running? A heat pump uses this same principle-extracting heat from the air and moving it to where it's needed. An air-to-air heat pump extracts heat from outside air. And amazingly, even in winter the air holds heat, even when the outside temperature gets down to zero degrees F.
Q. What is the cost of heat pump.
heat pumps typically cost more to install at front than electric heat systems, but they pay off in self by bring you efficiency comfort and lower electric bill on winter and they are the most efficient heating choice for electric houses .
Q. Are heat pumps reliable?
Because they use the same process, they are about as reliable as a refrigerator. In a study of air-to-air heat pumps performed elsewhere, after 20 years more than half of the heat pumps were still in operation. Of these that had been removed, less than half were for mechanical failures. The rest were for other reasons such as changing to a newer, more efficient, or different size.
Q. If I buy a heat pump, do I still need an air conditioner?
No! One of the biggest advantages to a heat pump is that it becomes an air conditioner in summer. Instead of moving the heat inside, it reverses operation and collects the heat from inside the house and moves it outside. All you need to do is change the settings on your thermostat. Don't miss out this summer by installing just an air conditioner. Install a heat pump for just a few hundred dollars more-then enjoy cooling this summer and efficient heating this winter.
Q. How do I know if my heating and cooling system works with the Nest Learning Thermostat?
The Nest Learning Thermostat works with over 95% of 24V heating and cooling systems, including gas, electric, oil, solar, hot water, geothermal, forced air, heat pump and radiant.
Q. Why should I contact a Nest Professional certified to install my Nest?

Q. What regular maintenance do heating and air conditioning systems need?
The most important part of HVAC maintenance aspect is maintaining unrestricted air flows. Dust, dirt, and debris are an HVAC system’s worst enemies. Whether it’s an indoor or outdoor unit, you must keep all filters clean and heat exchangers and coils free of restrictions. We recommend that your heating and cooling system be checked and serviced twice a year; ideally a spring and autumn . Also we recommend that you change your filter regularly, depending on the type of filter you have. This alone can eliminate many of the most common problems that need fixing and can significantly reduce the likelihood of a serious breakdown.
Q. Why do I need to change my filter regularly?
Regular filter replacement helps your heating and cooling system operate at peak levels and improves indoor air quality. It is important to change filters regularly to ensure proper air flow and to keep your home free from dust, allergens and germs. Depending on the type of filter you have, you may require weekly or monthly filter replacements.
Q. How often should I replace my filters?
In general, Angel Air recommends that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month for optimum efficiency and filtration for your specific system. We recommend that you visually check filters and filtering equipment monthly. If filters look dirty, they need to be cleaned or replaced.
Q. In addition to changing my filters, what maintenance should I do on my heater and/or air conditioner?
Most maintenance should be performed only by a qualified service technician. But here are some things that you can do to assure optimal performance:
• Keep ground mounted outdoor units clear of debris, clutter and weeds; they can reduce the airflow to the unit.
• Use caution with weed trimmers around the unit to prevent damaging control wiring.
• Keep pets away from the unit; pet urine can cause expensive damage.
• Dogs they like to bite the controls wirings coursing serious damage to the unit (most common problem)
Q. Is there anything I should check prior to calling for service?
Check to be sure that the air conditioner or furnace is turned on. Check that the breakers and the disconnects are turned on and be sure the thermostat is set correctly. Also make a note of any strange noises or smells.
Q. How do I know if my system is not working properly?
• Making strange noises?
• Has it been taking longer to cool down or heat up?
• Your thermostat wont go below 83 degrees at summer or wont go up than 65 degrees at winter?
• Have your utility bills been rising for no apparent reason?
Any of these are signs that you may have a problem that needs service. In most cases, the longer you delay, the worse any underlying problems will get. So be sure to call Angel Air to check out your system whenever you notice anything out of the ordinary.
Q. How are the sizing capacities of heating and cooling systems measured?
Heating and cooling systems sizing is based on B.T.U.H. (British Thermal Units Per Hour). Air Conditioning and Heat Pumps are also rated in tonnage. 12,000 BTUH equals one (1) ton. Residential systems can range from 1 to 5 tons.
Q. How important is it to get the right size of heating and cooling equipment?
Sizing HVAC equipment is very important from the standpoints of both comfort and energy use. Heating and cooling equipment that are over-capacity will not run as frequently or as long when it does run. In both cases, this may mean poor humidity control. It could also result in temperature variations or noticeable cycling. Over-capacity equipment will not be as energy efficient as properly matched capacity either. On the other hand, equipment that is under-sized, will obviously result in loss of comfort during temperature extremes.
Q. What size HVAC system should I have?
Unfortunately, there’s no simple rule of thumb for determining the ideal size of system for each home. For example, depending upon the construction of your home, one (1) ton of air conditioning can cool anywhere from 300 to 800 square feet of home. The only way to insure the size of the system you purchase will be large enough to heat or cool your home, but not any larger than you need, is to have your home’s individual heating and cooling needs evaluated by a licensed professional. Angel Air will estimate and inshore you get the right size to determine a selection of systems that will work best for your home’s needs and your budget.
Q. Is a system with more capacity better?
No. A larger heating system with more capacity delivers less comfort and costs more to operate. An air conditioner is at its least efficient when it is first turned on. A system with too much capacity will run in numerous short cycles, turning on and off repeatedly, therefore causing it to be less efficient. Also keep in mind that an air conditioner only removes humidity when it’s running, so a system with shorter run cycles doesn’t remove humidity from the air very well.
Q. How do I know if my A/C unit is big enough?
Bigger isn’t always better; its performance and efficiency that count. Before purchasing a replacement system you should always make sure your system is sized properly to match your needs and budget. Angel Air will thoroughly assess your home and comfort requirements to determine the proper size and make the appropriate recommendation.
Q. How is the efficiency of heating and cooling equipment measured?
When purchasing a furnace, heat pump or air conditioner, ALWAYS ask about its Efficiency Ratings. They will tell you how efficiently the unit uses fuel (gas, oil or electricity). The most-frequently used efficiency ratings are: • SEER (Seasonal Energy Efficiency Ratio): This ratio tells you the amount of cooling your system will deliver per dollar spent on electricity The SEER rating of any unit can range anywhere from 13 to 20. The higher the SEER the more efficient the system will be and the less it will cost in the long run to own and operate. • HSPF (Heating Seasonal Performance Factor): Similar to SEER, it is a measurement of efficiency of the heating portion of a heat pump. HSPF ratings range from 6.8 to 10; high-efficiency units have efficiencies of 7.5 HSPF or above. • AFUE (Annual Fuel Utilization Efficiency ratio): A measurement of the percent of heat produced by a furnace for every dollar of fuel consumed. The higher the AFUE rating, the lower the fuel costs. All furnaces manufactured today must meet at least 80%. Older furnaces (10 – 15 years or older) may fall below this minimum. Furnaces with AFUE ratings 80% are considered mid-efficiency; ones with AFUE ratings above 90% are considered high-efficiency. • MERV (Minimum Efficiency Reporting Value): A filter rating system relating to the size of the holes in the filter that allow air to pass through. The higher the MERV rating, the smaller the holes and the higher the efficiency in capturing contaminants. MERV rating range from a low of 1 to a high of 16. • ENERGY STAR: An Environmental Protection Agency designation attached to HVAC products that meet or exceed guidelines for high-efficiency performance above the standard government minimums.
Q. How can I increase the efficiency and life of my home’s heating and cooling systems?
A few quick tips:
• Clean and replace your filters frequently.
• Your system will heat and cool more evenly when the blower is in the “on” position while you are home . The blower provides constant air movement throughout the home, and allows for better filtration.
• Install shades, drapes, shutters, or screens on windows that are exposed to extreme sunlight to keep room temperatures at moderate levels. \
Q. Should I close the registers and doors to areas of the home that I do not use on a regular basis?
No. Every system is designed to cool a certain number of square feet. By closing registers and doors in certain rooms, you disrupt and decrease the systems’ airflow and efficiency. Your system will have to work harder to cool less space, making it cycle more and become less efficient.
Q. Should I turn my air conditioning system off while I away from home or at work?
The answer is NO.
you should keep your system ON at all time, all you need is to manage the temperature better at your thermostat before you live your home. reason if you turn off your system and go out when you return home and have your system turn back on your system will work hard to get back to your normal schedule or desire temperature and your system will be running non stop for an hour or two all depends of the temperature difference you set at the thermostat some times more than two hours cycle till your thermostat reach temperature and that's were the consuming of electricity take place but you can prevent this from happen by set your thermostat 5° to 10° degrees up or down before you live home so that way when you return home your system will run for no more than 20 to 30 minutes with is the average so you save energy that way best to have is a programmable thermostat or a smart like a Nest that you can control from your phone or computer at home or work
summer live temp at . 80°
winter live temp at. 65°
Call Angel Air today to get your programmable or smart thermostat install today at a great price.
Q. What air temperature should my air conditioner produce?
The air temperature produced by your system depends on the temperature of the air going into it. Generally, the air produced should be 15°-20° differential between return air at the filter and supply air register . So if the entering return air is 80°, the exiting supply air should be about 60°-65°. However, that only works on a system that is operating properly and has been running at least 15 minutes on a warm, dry day with a home that is about 80° inside. On a milder day, with an indoor temperature 70, the air coming out should be 50-55.
Q. At what temperature should I set my thermostat?
Temperature settings depend on the time of year and your personal preferences. In the summer, the average temperature setting is 76°-80°. In the winter 68°-72° is the norm. Remember, when leaving your house; try to avoid drastic temperature changes. Do not set your temperature back more than 5°; this will cause your unit to work harder to achieve the desired temperature setting.
Q. What are the advantages of a programmable thermostat?
Because they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. Plus, they allow you to automatically control the temperature in your home at different times of day without ever touching your thermostat.
Q. Is variable speed equipment superior and/or necessary?
Variable speed refers to a furnace’s or air handler’s indoor blower motor. Different speeds control the flow of air throughout your home. Variable speed blowers automatically change speeds to meet the different airflow needs of the heating and cooling cycles. Variable speed motors can use 1/7th the energy and are excellent for customizing comfort levels in different zones of your home. A variable speed motor can also help clean the air and control the humidity.
Q. What is two-stage heating?
Two-stage heating means a furnace has two levels of heat output: high for cold winter days and low for milder days. Two-stage furnaces start in the first stage, instead of reaching full capacity all at once. That means there is no sudden blast of air. The low setting meets household heating demands 80% of the time, allowing a two-stage unit to run for longer periods and provide more even distribution of heated air. Because the furnace operates mostly in its lower-capacity first stage, it burns less fuel than a furnace that always runs at full capacity and then has to shut off when the heating demand has been met.
Q. During the winter, my heat pump delivers warm air, but not hot air, and will operate for long periods of time. Is that normal?
Yes, this is normal. it will do that at the beginning when it start up but it will heat the air to around 80° to 105° and provides even comfortable, heating around the house – not a blast like the gas furnace those but will not give you this uncomfortable nose breading problem like the gas furnace . However, heat pump systems take couples of minutes to you really feel the strong hot air is normal but in other hand you saving money during a winter season.
Q. During the heating season, my heat pump makes a “whooshing” sound and I feel cool air coming from the supply registers. Is that normal?
Totally normal. During the cold weather months, frost can accumulate on the outdoor coil. This can cause the heat pump to go into a defrost cycle anywhere from 1-10 minutes, depending on the amount of ice on the coil. This is temporary; the system will call for the electric heat strip for that period of time then return to the heating mode once the ice is gone.
Q. Why does my heat pump system sometimes freeze up?
Several factors that can cause system freezing. First, if running in the cooling mode check your filters; restrictions in air flow can lead to freezing. Next, thaw the system out by turning off the cooling and running the fan. Also, try turning the system to the heat mode until the ice has melted. If the problem recurs after checking for air restrictions and thawing your system thawed, schedule a service call with Angel Air .I will check the refrigerant level. They may also have to clean the evaporator coil, check the blower speed and check for any intermittency in blower operation. A service technician can also evaluate other conditions that may make your system prone to freezing and recommend the best course of action.
Q. What is I.A.Q.?
I.A.Q. stands for Indoor Air Quality. Today, various products are available as add-ons to your existing heating and cooling system to improve the quality and healthiness of the air inside your home. These items include • Electronic- or Media-Type Air Filters: Filtering the air within your home will help eliminate smoke, pollen, odor, dust mites and allergens. This will allow you to breathe easier, sleep better and enjoy your home more. • Whole-House Humidifiers: Whole-house humidifiers provide consistent humidity levels throughout the home, and some models even adjust the humidity level automatically. The average heated home has a humidity level of less than 20%. The recommended humidity level in the winter should be between 35% and 45%. • Air-to-Air Heat-Recovery Ventilators: These ventilator systems remove stale air from inside the home, while bringing in fresh air from the outside that is warmed during the transfer process.
Q. How important is air quality and what factors need to be considered?
An air quality system can greatly improve both your comfort and your health. The areas of air quality to consider are
(3) humidity control, and
(4) ventilation. A wide number of air quality features come standard with many new heating and air conditioning systems; others can easily be added to existing systems. Contact Angel Air to discuss your air quality options.
Q. Do electronic air cleaners really work?
Electronic air cleaners can greatly improve home air quality and comfort levels. If you suffer from allergies or have pets, they’re a must. Some electronic air cleaners can even remove dust particles and pollen as small as .10 micron. Angel Air offers a variety of air filtration devices. Call today to discuss your options.
Q. What is the primary function of a heat exchanger?
A heat exchanger is a piece of metal designed to separate the safe warm air that is circulated through your home from the poisonous carbon monoxide gas created during the combustion process when you operate your furnace.
Q. What are possible causes of cracks in a heat exchanger?
The natural heating and cooling cycles of a furnace can lead to cracks in a heat exchanger. A furnace that is being overworked or stressed is more likely to have a premature breakdown and potential carbon monoxide leak. Dirty air filters, blocked vents, and burners that are not firing properly and disrupting the combustion process can all contribute to the detrimental stress that may lead to cracks in a heat exchanger.
Call Angel Air today to perform a carbon monoxide test in your furnace if you don't feel secure.
Q. What are the potential dangers of operating your HVAC system with a cracked heat exchanger?
If a crack in the heat exchanger allows carbon monoxide to escape into your home you may experience dizziness, light-headedness, flu-like symptoms, or even death by asphyxiation. Carbon monoxide limits the body’s ability to take in oxygen. This is an extremely dangerous situation to have in the home, because the effects of carbon monoxide poisoning may be gradual and undetected.
Q. Should I be concerned about carbon monoxide in my home?
Very concerned. Carbon monoxide (CO) is a gas produced during the combustion of fuels. It’s colorless, odorless, tasteless…and can be lethal. Even trace amounts can impair your brain function and impact your health. Cracks, leaks, obstructions and other malfunctions in your heating system can cause carbon monoxide to develop and accumulate. Short-term exposure to carbon monoxide usually results in flu-like symptoms: nausea, headaches, dizziness, fatigue. Long-term exposure can eventually lead to unconsciousness or death. Horizon Services recommends the following to minimize carbon monoxide risk: • Keep heating equipment in good repair by scheduling regular inspection and maintenance. • Keep furnaces, chimneys and vents free of obstruction. Watch out for birds, squirrels and other animals who sometimes build nests in these areas. • Install a carbon monoxide detector, available at any home supply store. • Periodically open windows in winter to let in fresh oxygen-rich air inside and let out any potential carbon monoxide. • If you use an older gas stove or heater, look at the color of the pilot light. The flame should be at least 80 percent blue. If the flame is mostly yellow, it could be producing carbon monoxide, so have the unit checked by a professional immediately. Be sure to tune up your gas system at least once a year. Today’s modern heating systems burn cleaner than older systems, minimizing or eliminating your risk of carbon monoxide exposure. Contact Angel Air for more information.
Q. How important is it to have a quiet heating and air conditioning system?
Extremely important. Sound intensity is measured in units called decibels (dB). A normal conversation is about 60-70 dB. A telephone dial tone produces 80 dB; a lawn mower produces 107 dB or more. Sustained exposure to sound levels of 90-95 dB may lead to hearing loss, so it’s important to own the quietest heating and cooling system you possibly can.
Q. What is the ideal indoor humidity level?
The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) recommend a household humidity level between 30 and 60 percent.
Q. Why are humidifiers used more in heating than cooling?
The average comfort range for relative humidity in a home is from 30 to 35%. When cool outdoor air enters your home, it tends to dry out as it warms up, which can cause static electricity build-up and sinus problems. A humidifier will add moisture back into the air and minimize these problems during the winter months. However the humidity level achieved in a home is effected by how tight a home is, how often the doors open and close size and style of humidifier.
Q. Are there any air conditioning systems that are safe for the environment?
Yes. Several manufactures have developed new systems that contain environmentally-friendly refrigerants such as R-410A and similar blends. 410A is a chlorine-free coolant that is safe for the Earth’s ozone-layer and delivers superior cooling than traditional refrigerants. In fact, after 2010, systems that used R-22 will be phased out and replaced with 410A.
All new equipment Angel Air used it come with r410a Freon.
Q. How do I know whether my heating and cooling equipment needs replacement or just repair?
Not an easy question to answer, but here are some factors to consider:
1. The age of the current system. Today, any system that is more than 10 years old is probably behind the times in terms of efficiency.
2. Does the current system provide the level of comfort that you want? There is a growing difference between “builder grade” and consumer choice in what a system can offer in terms of comfort and convenience.
3. How much will the repairs cost…and how many more repairs will you need in the future?
Is keeping an older system operational worth the time, the money and the inconvenience?
Sometimes you need to know when to cut bait and say goodbye to your old heater or air conditioner. Angel Air, can work with you to prepare a side-by-side cost-benefit analysis so that you can compare whether it is more advantageous for you to keep your current system or replace with a newer one.
Q. It’s been years since I shopped for a new heating and cooling system. What changes in technology and equipment do I need to know about?
If you’re deciding on a new system and have not kept up with advances in the industry, you will be amazed at the number of choices that you have to make. Today’s comfort systems offer a surprising number of options and combinations – from individual heaters and air conditioners to integrated systems. Systems can vary widely in terms of energy efficiency and cost. The ability of systems to monitor conditions and adjust automatically has increased dramatically. And a wider variety of air quality add-ons are available than ever before. These changes make the replacement decision even more complex than ever, so you can see how important it is to find a HVAC company that will work with you to develop a system for your situation and budget. At Angel air , my goal is to be a company that will partner with you to not only install a system that is appropriate for your situation, but then help you keep the system operating at peak performance.
Q. When should I replace my existing heating and/or air conditioning unit system?
All systems and units are different. Here are some rough lifespan guidelines to help you decide whether fixing or replacing is the right decision: • Average Lifetime of an Air Conditioner: 12-15 yrs. • Average Lifetime of a Furnace: 15-20 yrs. Keep in mind that these are just guidelines. Some units last longer than that with regular maintenance and replacement of parts. But if a unit has been repaired repeatedly, or has been run excessively, it might make more sense to replace it even sooner. Paying for repairs to an old or inefficient system often simply prolongs the inevitable. An older system that breaks down once is likely to break down again…and again. That means more emergency service calls or, worse yet, the risk of damage to your home or to other components of your heating and cooling system. There’s also an ongoing cost factor to consider. Restoring your old system will only bring it back to its current level of energy efficiency. After you’ve recovered from the repair bills and the frustration of system breakdowns, you still won’t save on your energy bills. Some replacement systems can cost less than the cost of repeated repairs. And in many cases, installing a new heating and cooling system can actually pay for itself in energy savings within a relatively short time. Also, when replacing a heater or air conditioner, it is usually best to replace both units at the same time. This way, you’ll save on installation costs and both units can be serviced on the same maintenance schedule and have the same approximate lifespan.
Q. What should I look for when choosing a new heater, heat pump or air conditioning unit?
Here are some general rules of thumb when you are ready to replace your existing equipment:
• Choose a manufacturer that has a good reputation for quality and durability. Angel Air has them
• Choose a model that with a high efficiency rating to bring you better comfort and lower your seasonal energy bill.
• Choose the correct equipment size and system for your home.
• Don’t just buy a unit just because it is on sale and seems like a great deal at the time;
• Finally, choose a reliable company like Angel Air with excellent customer satisfaction and a track record of service after the sale. Check out contractor ratings and reviews online from Better Business Bureau. Chances are you’ll get plenty of recommendations for Angel Air!
Q. How much does a new replacement system cost?
Due to the many different makes, models and customer needs, price is an issue that can only be solved by doing a thorough evaluation of your home and existing equipment. At Angel Air, there is no charge for an in-house replacement proposal.
Q. What do I do if I can’t afford a new HVAC system?
Angel air offers a financing option through a financing company . and they can recommend the financing plan that’s best for your needs.
