Heating and Air Questions

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

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 Dunns Heating Cooling and Plumbing we recommend semi-annual maintenance for your AC system.

Is it necessary to service AC every year?

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 Dunns Heating Cooling and Plumbing we recommend having your HVAC system serviced 2x per year so you stay comfortable in all seasons.

How much does it cost to replace a central air conditioning unit?

The cost to replace your central air conditioning unit will vary based on several factors:

  • The size of your new AC system
  • The square footage of your home
  • SEER of your new HVAC system
  • Your comfort goals

At Dunns Heating Cooling and Plumbing, your comfort is our #1 concern along with staying within your budget. This is why we offer free system replacement estimates so you have a clear picture of what your new air conditioning system will cost upfront.

Why is my AC running but not cooling?

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 Dunns Heating Cooling and Plumbing 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.
