Question 1

What happens if you don’t service your air conditioner?

Accepted Answer

AC service allows your HVAC system to operate at maximum efficiency. If your AC unit is not serviced on a regular basis it can cause minor problems to turn into major headaches. Less than efficient AC systems not only decrease your comfort they also cost you more in utility bills as they age. At Dunn’s Heating, Cooling, Plumbing, and Electrical we recommend semi-annual maintenance for your AC system.

Question 2

Is it necessary to service AC every year?

Accepted Answer

The answer is yes. Having your AC serviced at least 1x a year allows a licensed technician to keep a record of minor issues with your AC unit as well as repair them quickly. HVAC maintenance helps your system operate efficiently which increases the comfort of your home. At Dunn’s Heating, Cooling, Plumbing, and Electrical we recommend having your HVAC system serviced 2x per year so you stay comfortable in all seasons.

Question 5

Why is my AC running but not cooling?

Accepted Answer

Often if an AC system is running but not cooling a clogged or blocked condenser coil can be to blame. If your air conditioner has stopped cooling your home we recommend calling a licensed HVAC professional from Dunn’s Heating, Cooling, Plumbing, and Electrical to diagnose your AC issue. Trying to diagnose or repair your air conditioner on your own can not only turn a small problem into a large one, it can also be dangerous.
