What do I do if my A/C is blowing warm air?

Check your thermostat setting, check your breaker and then check your filters. If problem still persists, call to schedule our service technician for a full diagnostic inspection.

What exactly is the equipment outside?

The equipment located outside your home is either the air conditioner, heat pump or package unit.

What is the equipment in my attic?

The equipment located in the attic of your home is either your furnace or air handler.

How often should I change my filters?

We recommend changing your filters every month to reduce failures and to optimize equipment performance.

What do I do if I smell gas?

Exit the property to get fresh air, then call the fire department. 911 dispatchers will respond immediately to secure the property. Seek medical assistance if you experience carbon monoxide exposure symptoms (nausea, headache and/or dizziness and respiratory distress). Virginia Natural Gas can be contacted on their 24 hour emergency line at 877-572-3342. Call Kellam Mechanical for repairs after leaking gas source is secured/shut off. Ensure your safety by installing a carbon monoxide detector.

What is refrigerant?

A chemical that produces a refrigerating effect while expanding and vaporizing. Most residential air conditioning systems contain R-22 or R-410 refrigerant. R-22 and R-410 are regulated by international controls under the Environmental Protection Agency.

Note: Equipment using R-22 will no longer be produced after the year 2010 which will increase costs due to limited availability.  R-22 will no longer be produced after 2020.  Homeowners with equipment using R-22 can schedule a consult with one of our experts to discuss upgrading to high efficient equipment using EPA approved R-410 refrigerant.
