"The service that we received from Aires Heating and Cooling, LLC was great. I really can't say how it could have gone any better. Our furnace broke down, tried a couple easy troubleshooting steps over the phone, and when we couldn't get it going, the tech was over as soon as he could. This is the time of year where he was busy with other customers, so the amount of time we waited was explainable. Didn't have parts right away on his van, but we didn't wait for more than 24 hours before he found another tech that did have the parts for our furnace. Excellent friendly service. Thank you very much for all the help, Aires Heating and Cooling, LLC."

"Austin installed A/C in our newly remodeled home and we will continue to go through him for any future HVAC needs. He was efficient, thorough, and transparent throughout the entire process, answering any questions we had. As well as reassuring us we could reach out to him after the job was done if we ever had any problems down the road. We highly recommend his services and the peace of mind he provides!"

"Mario did a great job cleaning the ducts in our house and our dryer vent. The before and after pictures showed how dirty our vents were and how wonderfully clean they were when he was done. We just moved into our home and it is reassuring to know that everything is cleaned out now. I highly recommend Mario and his duct cleaning business!"

"I called ANG Heating&Cooling looking for a solution to our very dry and uncomfortable situation in our home. Alex came out to our home to have a look at what was going on, within a few minutes Alex had a plan together and we were scheduled for a whole home humidifier, in addition to some added supply and return runs to get that conditioned air moving throughout our home. Let me just say Alex was spot on WOW what a difference very very pleased! very comfortable! Alex was prompt, professional, punctual and very knowledgeable. Alexs was very neat and tidy! A true craftsman of his trade! Everything looks great,great rates as well! I strongly recommend giving ANG a call for any of your future HVAC needs. Thanks again Alex!"

Heating and Air Conditioning questions, answered by experts

It depends on the specifics of your warranty. The motor is likely not covered if you’re working with a limited warranty. The same goes for other components like the compressor and evaporator coil. Some extended warranties will cover the blower and fan motor, so read the fine print before signing up. Additionally, the manufacturer may offer a warranty for the parts, including the motor, though there’s likely to be a strict time limit for this coverage.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.
