"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!"

Heating and Air Conditioning questions, answered by experts

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.
