Thinking About a New AC or Heat Pump?

If your air conditioner is older, uses an outdated refrigerant, or needs a major repair, a new system may cost less over its lifetime and lower your energy bills. Many Hermitage homeowners choose a heat pump, which heats and cools with one system. New installations include a 10-year parts warranty when registered, and financing starts at $199/month (subject to credit approval).

Simple Ways to Prevent AC Breakdowns

Replace your filter every one to three months, more often with pets.
Keep grass clippings, leaves and shrubs away from the outdoor unit.
Get a spring tune-up before the first heat wave.
Don't close too many vents; it can freeze the coil.
Ask us about duct cleaning and insulation if some rooms never cool down.

Hermitage AC Repair FAQs

My AC is running but the house won't cool. What should I check?

Check the filter, make sure the thermostat is set to "cool" and "auto," and look at the outdoor unit to see whether the fan is spinning. If the filter is clean and the house still isn't cooling, call us. A failed capacitor is a common, quick fix.

Why is water leaking from my indoor unit?

Usually it's a clogged condensate drain or a frozen coil that's melting. Turn the system off and call for service to prevent water damage.
