Do you do the HVAC work yourselves?

No. We are a referral service that connects you with independent, licensed local HVAC contractors who do the work.

Is the estimate free?

Requesting an estimate through this site is free. Some contractors charge a diagnostic or trip fee for repair visits, so ask when they contact you.

What should I do if I smell gas?

Leave the home right away without flipping switches, then call 911 or Xcel Energy's gas emergency line from outside.

How long do furnaces last in Centennial?

Many gas furnaces last 15 to 20 years with regular maintenance. Age alone is not a reason to replace, but it matters when a big repair comes up.

Does Centennial's altitude affect HVAC equipment?

Yes. Gas furnaces are typically adjusted per the manufacturer's high-altitude instructions, and proper sizing matters for both heating and cooling.

Do I need a permit to replace a furnace or AC?

Centennial and most metro cities require a mechanical permit for furnace, AC and heat pump replacements. Your contractor normally pulls it.

Are heat pumps a good fit for Centennial?

Cold-climate heat pumps can handle most Centennial winter weather, and many homeowners keep a gas furnace as backup for the coldest nights.

Are there rebates for new equipment?

Xcel Energy and some local governments have offered rebates for heat pumps and efficient equipment. Programs change, so confirm current details with your installer.

Should I replace my swamp cooler with central air?

It depends on your ductwork and budget. Evaporative coolers work well in Centennial's dry air, but many homeowners switch to central air or mini-splits for more consistent cooling.

How much does a furnace repair cost?

Typical Centennial repairs run from about $150 to $1,200 depending on the part. Use the cost calculator for a ballpark.

Repair It or Replace It?

Many Centennial furnaces and air conditioners are 15 to 20 years old. A few honest questions help you decide whether a repair still makes sense.

Age matters

Gas furnaces often last 15 to 20 years and central air conditioners somewhat less, so a major repair on an old unit deserves a second look.

Safety comes first

A cracked heat exchanger or a venting problem is a safety issue, and many technicians will recommend replacement rather than a patch.

Compare the totals

Ask for the repair price and a replacement price side by side, along with any utility rebates that might apply to a new system.
