Heating and cooling for central Oklahoma

You asked for a new AC.
We’ll ask why the back bedroom
has never been comfortable.

A system sized off the old label repeats the old mistakes. We measure the house, test the ducts and tell you what will actually change before you spend anything.

  1. Measured, not guessed

    Every replacement starts with a room-by-room load calculation and a duct test.

  2. The price comes first

    You see the full price in writing before any work starts.

  3. Here after the install

    Two tune-ups a year, one phone number, and a technician who already knows your system.

Urgent help What to do right now

Pick the problem. You’ll see what to check before a technician gets there, and what to leave alone.

Check the thermostat, the filter and the breaker

  1. Set the thermostat to Cool, at least 3 degrees below room temperature. If the screen is blank, change the batteries.
  2. Pull the filter. If you can’t see light through it, replace it.
  3. Find the breaker for the outdoor unit. If it tripped, reset it once. If it trips again, leave it off.
  4. If the outdoor unit hums but the fan doesn’t spin, turn the system off at the thermostat so the compressor doesn’t overheat.
Book an AC repair

Turn the cooling off and let it thaw

  1. Set the thermostat to Off and the fan to On. Moving air melts the ice faster.
  2. Put towels under the indoor unit. Thawing can take several hours.
  3. Replace the filter if it’s dirty. Poor airflow is the most common cause.
  4. Don’t chip at the ice. The coil and refrigerant lines puncture easily.
  5. A light frost on a heat pump in winter is normal. Call if it stays iced over for hours.
Book a technician

Five things to check before you call

  1. Set the thermostat to Heat, above room temperature. If the screen is blank, change the batteries.
  2. Find the furnace switch. It looks like a light switch, on or near the unit. Make sure it’s on and the breaker hasn’t tripped.
  3. Check the filter, and that the furnace’s front panel is fully closed. Most furnaces won’t start with it off.
  4. If a light is blinking, count the flashes. That code tells the technician which part to bring.
  5. Press reset once at most. If it fails again, leave it off.

Shut it off and protect the floor

  1. Set the thermostat to Off so the unit stops making condensation.
  2. If water is near outlets or wiring, switch off the unit’s breaker before you touch anything.
  3. Soak up the water and empty the drain pan with towels or a wet vac.
  4. Many systems have a float switch that stops the AC when the drain backs up. If the cooling just quit, that may be why.
Book a technician

Turn it off and note the sound

  1. For banging, grinding or screeching, turn the system off at the thermostat. Running it can finish off a motor.
  2. Note whether the sound comes from the indoor or outdoor unit, and whether it happens at start-up or all the time.
  3. Take a 10-second video on your phone. It helps the technician bring the right part.
  4. Don’t reach into the outdoor unit. The fan can start without warning.
Book a technician

Leave now and call 911 from outside

  1. Don’t touch light switches, the thermostat or appliances. No flames.
  2. Get everyone out. Don’t stop to open windows or look for the leak.
  3. Once you’re well away from the house, call 911 or your gas company’s emergency line.
  4. Stay out until they say it’s safe. Call us after that.

Get into fresh air and call 911

  1. Get everyone outside right away, pets too.
  2. Call 911 from outside. Tell them if anyone has a headache, dizziness or nausea.
  3. Stay out until responders say it’s safe, even if the alarm stops.
  4. Have the furnace and other gas appliances inspected before anyone uses them again.
