Safety first: gas, carbon monoxide and sparking

Some problems need the gas company or 911 before they need us.

  • You smell gas. Leave the house now. Don't flip light switches, start a car in an attached garage or use your phone inside. Once you're outside, call your gas company's emergency line or 911.
  • Your carbon monoxide alarm is going off. Get everyone, pets included, into fresh air and call 911. Don't go back in until responders say it's safe.
  • You see sparking or smoke from the equipment. If you can do it safely, shut the system off at the breaker. If there's smoke or fire, get out and call 911.

Once the house is cleared, call us and we'll find the cause.

Same prices, day or night

An emergency repair costs exactly what the same repair would cost on a weekday afternoon. There are no overtime fees on nights, weekends or holidays.

The process is the same too. The diagnostic is $39. We find the problem, explain it and give you a firm, flat-rate price before any work starts. If you approve the repair, the full $39 is credited toward it. There's no travel surcharge anywhere in our service area, and most Lexington calls are same-day.

What counts as an HVAC emergency

An HVAC emergency is any failure that puts people, pets or your house at risk. These are the calls we'd tell you not to wait on:

  • No heat in freezing weather. Pipes can freeze and the house can get dangerously cold, especially for infants and older adults.
  • No cooling in extreme heat, with vulnerable people at home. Heat is hardest on older adults, babies, pregnant women and anyone with heart or breathing problems.
  • Water leaking from the system, especially from an air handler in the attic or above a finished ceiling.
  • A burning smell that doesn't fade within a few minutes of the system starting.
  • A breaker that keeps tripping when the system tries to run.

If you're not sure, call or text us. We'll tell you honestly whether it can wait until morning.

What to do while you wait

A few simple steps can protect your family and your house until we get there.

No heat in winter

Close blinds and curtains at night, and open them on the sunny side during the day. Close doors to rooms you aren't using. Let faucets on outside walls drip to keep pipes from freezing. Space heaters are fine if they have three feet of clear space around them and plug straight into the wall. Never use a gas oven, stove or grill to heat the house.

No AC in extreme heat

Close blinds on the sunny side, stay on the lowest floor and run fans. Drink water and check on anyone older or medically fragile. If someone gets dizzy, confused or stops sweating, call 911. If the house gets too hot to stay in, go somewhere cool until we arrive.

Water leaking

Turn the system off at the thermostat. If water is near the furnace, air handler or any outlet, turn off the power switch next to the unit. Catch what you can with towels or buckets, and use a wet vac if you have one.

Burning smell or tripping breaker

Turn the system off at the thermostat. If the smell is strong or the breaker keeps tripping, switch the breaker off and leave it off. Resetting a breaker over and over can damage the equipment and create a fire risk.

Emergency HVAC Repair questions

Do you charge more for emergency calls?

No. There are no overtime fees on nights, weekends or holidays. An emergency call gets the same $39 diagnostic and the same flat-rate pricing as a weekday call, and the $39 is credited in full if you approve the repair. You'll know the exact price before any work starts, whatever time it is.

Will a real person answer at 3 a.m.?

Yes. We're open 24/7, and one of the owners, Ahmad or Ammar, answers the phone. There's no answering service taking a message for the morning. Call or text (859) 684-3259, tell us what's happening, and we'll give you a realistic idea of when we can be there.

How fast can you get to me?

Most Lexington calls are same-day, and we're open around the clock. We don't promise a specific arrival time we can't keep. When you call, we'll tell you honestly where we are and when to expect us, so you can plan around it.

Is a broken AC an emergency?

It depends on who's in the house and how hot it is. For healthy adults on a warm night, it can usually wait until morning. For older adults, babies or anyone with a medical condition during a heat wave, treat it as an emergency. If you're not sure, call and we'll help you decide.

What should I do if I smell gas?

Leave the house right away. Don't flip switches, use your phone inside or start a car in an attached garage. Once you're outside, call your gas company's emergency line or 911. After they've cleared the house, call us and we'll check your furnace and other gas equipment.

Is it safe to use space heaters while I wait?

Yes, if you use them carefully. Keep three feet of clear space around each heater, plug it straight into a wall outlet instead of an extension cord, and turn it off when you leave the room or go to sleep. Never use a gas oven, stove or grill to heat your home.
