"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

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.
