🔧Pro Tip: If your AC is running but your home still feels humid… don’t ignore it.

Your system should be removing moisture as it cools. Excess humidity can be a sign something’s off—and it can make your home feel warmer than it actually is.

Comfort isn’t just temperature.

☀️ Summer in Maryland means your HVAC system is about to work overtime.

One of the best things you can do before peak heat hits? Change your air filter NOW instead of waiting until July. A clogged filter can restrict airflow, reduce efficiency, and force your system to work harder than it should.

At Cornett Heating & Cooling, we help homeowners stay ahead of breakdowns before the hottest days of the year arrive.

“I just completed my semi-annual HVAC maintenance. The technician arrived on time and performed the maintenance quickly and professionally both inside and outside. He answered all the questions I had about the system. Cornett Heating and Cooling is an excellent company from the scheduling process through the entire work process. They are the only company I would use. There is no better company around.” - Allen D.

We really appreciate you taking the time to share this!
Our goal is to make every maintenance visit easy, professional, and informative. It means a lot to hear that reflected in your experience.
