While you wait

What to do right now.

Pick what’s happening. About one in five calls is solved by one of these before the truck arrives. If it is, we cancel the visit and you owe nothing.

  1. 1

    Set the thermostat to Heat and 5° above the room. Give it 5 minutes.

  2. 2

    Find the furnace switch (looks like a light switch on or near the unit). Make sure it’s on. Check the breaker.

  3. 3

    Pull the filter. If you can’t see light through it, swap it and turn the furnace off for 30 seconds, then on.

  4. 4

    Still cold? Send the form or call. Pipes can freeze in hours.

The price, before you call

$99 to find it.
Written price to fix it.

Day or night. The $99 comes off the repair if you go ahead. If the honest answer is “replace,” you see both numbers and the diagnostic is credited toward the new system.

  • No overtime fees

    Nights, weekends, holidays. Same price as Tuesday at noon.

  • No surprise invoices

    The number you approve is the number you pay.

  • Fix first

    We repair what can be repaired. We don’t sell furnaces at midnight.

  • Licensed, bonded, insured

    A Colorado LLC with a real address in Englewood.

Emergency questions

Before you call.

What does an emergency visit cost?

The diagnostic is $99, day or night, and it’s credited toward the repair. There are no overtime, holiday, or after-hours fees. The repair price is written down before we start.

How fast can you get here?

Same day across the Denver metro. No-heat calls in freezing weather and no-cooling calls in a heat wave go to the front of the line and are usually reached within a few hours.

Do you really answer at 2 a.m.?

Yes. A real person in Denver, not an answering service in another state.

What if you can’t fix it tonight?

We make it safe, get you temporary heat or cooling if we can, and come back with the part the next morning. You only pay the diagnostic until the repair is done.
