Emergency Service

When It Can't Wait

Some calls can’t wait until Monday. A furnace that quits on a freezing night, an AC that dies during a heat wave with kids or older family members at home, or commercial equipment that has to stay cold. Gabe has taken those calls in the middle of the night.

If we can’t pick up, leave your details and we’ll call you back. Emergency hours: [PLACEHOLDER: emergency hours].

Our Process

How a Job Works with Us

Four steps, no surprises.

Call (720) 701-3810 or send the form. We'll set a time to come out.

We look at the size of your home, the area that needs service, and the system you have now.

You get more than one option, shown on our tablet, with a written contract you can sign on the spot or by email.

Once you choose, we check equipment with our supplier. When it's in stock, many jobs can start the next day.

Why K&G Builders HVAC

We Show You What We Find

Some customers have been burned by a contractor who found a problem and never showed them why. We'd rather earn your trust by showing you.

Simple checks first

Capacitor, relay, wiring, then the bigger parts.

One cause at a time

We follow the system in order until the real problem shows up.

You see it too

We explain what we found and what it means for you.

Then we talk options

A clear price for each path, and no pressure to pick the priciest one.
