HVAC Emergency Service

How Do I Know I Need An AC Repair?

Your home comfort system will give you signs that it needs attention. Look for the following signs that you need a heating or AC repair:

Odors

If your furnace, heat pump, air conditioner, or ductless system is emitting odors, don’t delay. Our customers report everything from sulfuric or 

chemical smells, to hot or burning smells. Many are harmless, and it’s normal to experience certain smells when a system is used for the first time after idling. However, it’s important to troubleshoot your system if it’s emitting odors.

Patchy
Temperatures

It’s normal that different areas of your house feel slightly different in temperature. Normally, this is caused by changes in the sun exposure, opening and closing of doors and 

windows, and changes in activity. However, if areas of your home feel constantly uncomfortable, too hot or too cold, your system isn’t doing its job. We can help.

Noises

Your house will emit a lot of strange noises that go bump in the night.The important thing is to identify the source. If you suspect that any component of your HVAC system

is responsible for knocks, clunks, or grinding sounds, let us know.

Changes In
Function

Your HVAC system shouldn’t turn on and off constantly, turn on and then stop abruptly, take a long time to turn on after thermostat adjustments, or give you any other trouble.

  If your system is unresponsive for periods of time, never stops running, or doesn’t reach the designated temperatures, we’ll investigate the cause.

Leaks

Leaks of air, other gases, or moisture can be problematic for an HVAC system. Leaky ducts can cause your system to overwork, cycle too frequently, and

overuse power to your home. However, moisture leaks, drips, or signs of ice could indicate issues with your air condenser or other sensitive system components.

Loss Of Function

If your heating or air conditioning system fails to turn on or respond to commands from your thermostat, it’s time to call the pros. We can help you determine what’s

going on and repair your system fast.
