"Steve and his team are very professional and get the job done in a timely fashion. We had three quotes on a new HVAC system and his was by far the lowest. They were wonderful to deal with and would hire them again without question."

"Fixed my poor ventilation of my dryer duct. Don't know how effective the hvac duct cleaning was. I figured it didn't hurt to do it once since it's never been done but mostly purchased deal for dryer duct."

"My AC died on me in the middle of the night, so I texted them instead, using the Home Advisor App...They responded before I had my first cup of coffee in the morning! They sent out Art to help me shortly after hanging up... WOW !!! Art knew right away the problem and went to his truck for the part, and it was fixed in minutes. Even before the HOT SUN started to bake my house... I am extremely grateful. They now have me as a permanent customer for both my central air and heating systems... I highly recommend it."

Heating and Air Conditioning questions, answered by experts

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.

Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.
