"

We had some questions about some problems under the house. A man came out and explained to me what they could offer to try to solve those problems. They call it the doctor energy specialist or something, I don?t know. It?s about removing moisture and other things from under the house and making sure the ducts are properly attached and that they are insulated properly. That the house insulation is proper and they sealed most of the vents to keep the wet air from coming in. They put in a dehumidifier and all that stuff. They did a large amount of work. They put in a new moisture barrier and corrected some problems that we already paid somebody to do and they didn?t do. They even attached the dryer duct, which wasn?t attached and the air was going out all under the house. They were very very good. They did what they said. They took all the trash and everything they found out from under there. This whole experience has been a nightmare. Those people at GSM were super. The inspection he did not charge us for, but we put an amount down on the work they were going to start doing. It was excellent because he went under the house, he took pictures of all the things he was going to tell me about, and then he explained the different treatments that were available and the prices for those treatments. And what particular things they would correct. It was very clear and he was very good about answering my questions. He seemed very experienced.

"We purchased a new Clayton home in late 2023 and everything seemed good at first. After several times over a year of having HVAC techs from Clayton come out for a cooling issue, eventually the warranty ran out on the AC. Then we had another supposedly reputable HVAC company come out and said it was a lot of issues outside and would cost almost $2000 for a repair that may or may not work. We went thru Angis list and got in touch with Quality Air. The tech came out and went thru our system and located the issue inside that was never installed from the Clayton homes store. Nathan had our system up and running and has been cooling excellent ever since. Before, our system had a very hard time keeping up with the selected temp.. but now we sit in cool comfort and it has never ran so great. Thank you Nathan, and thank you Quality Air!!"

"We highly recommend U.S. Energy Solutions...Mom and dad had some unforeseen electrical issues that needed to be fixed in their kitchen due to an inspection review before selling their home. I went to Angie's List put in a request for suggestion and U.S. Energy Solutions got right back to me. We set up and appointment! Electrician was prompt, courteous, professional and friendly. He diagnosed the issue straight away, took the time to show us and explain the problem. His confident approach to the problem was reassuring and was fixed quickly! All the way around a great experience!!"

"They showed up promptly to access the problem and jumped right on the problem and ended up having to replace the whole system and they didn't quit til they repaired the damper system as well. Our HVAC has never worked so good! They could however work on keeping me informed of their arrival times. I had to call them each day they were expected to get an ETA."

Heating and Air Conditioning FAQs, answered by experts

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.
