Furnace repair reviews

Tracy Zielinski Nov 2019 Milwaukee furnace repair service 5 star review

Best experience ever! Called after hours when our furnace went out. Owner answered and right away offered to give me some trouble shooting tips. The information he offered did the trick. Now to me this is true honest customer service. Most businesses would have told us they’d have to come out to see the problem. Instead he gave us a couple things to try and said he’d call us back in a few minutes so we could try his suggestions. Sure enough he definitely knows his stuff and yes he followed up as promised. This is our 2nd experience with Prompt and we will continue to use them for our heating and cooling needs.

Furnace repair FAQ:

How long do furnace repairs take?

Every furnace repair is different, so it depends. Once we know what the problem is, the technician can give you a better idea of how long it will take to fix.

We’ll always do our best to repair your furnace as efficiently as possible. We respect your time, which is why we have 30-minute windows for service calls (most companies give a 2-4 hour window).

Should I repair or replace my furnace?Residential furnace repair service in Milwaukee, Wisconsin

A rule of thumb is when the cost of repairs approaches half the cost of a new furnace, you’re probably better off replacing it. If your furnace goes from relatively problem-free to needing repairs more frequently all of a sudden, that may be another sign it’s reaching the end of its service life (on average 15-20 years for a household furnace).

Before you decide to invest in a new furnace, get a professional opinion. We’ll always help you get the longest possible service life out of your heating system before recommending replacement.

Does homeowners insurance cover furnace repair?

In general homeowners insurance won’t cover furnace repair caused by normal wear and tear or old/faulty equipment. If your furnace was damaged in a fire, break-in or natural disaster, it most likely is. Some insurance companies offer coverage for mechanical breakdown of appliances that you can add to your policy. You’ll need to check your insurance policy and contact your agent to make sure.

On the other hand, most home warranties cover furnace repair or replacement – but you’ll need to read your warranty to find out what constitutes a valid claim and how it will be handled.

Can a broken furnace cause carbon monoxide?

Yes. If the burner isn’t working right or the heat exchanger has a crack, carbon monoxide gas can escape. It’s important to have carbon monoxide detectors on each level of your home. We recommend regular furnace maintenance to help prevent dangerous situations like carbon monoxide being released from a malfunctioning heating system.

Can a furnace explode?

Technically, it’s possible for a gas furnace to explode - but it’s extremely unlikely. Most furnaces have built-in safety features including automatic shutoff if conditions are dangerous.

Are old furnaces dangerous?

They can be. If not properly maintained, older furnaces can develop unnoticed cracks in the heat exchanger which allows carbon monoxide gas to leak out. Older furnaces can also develop leaks in the gas line, which is very dangerous. Regular furnace tune-ups help prevent the dangers associated with aging furnaces.

Why is my furnace not working?

There are many things that can cause a furnace to make strange noises or stop working, and we’ve seen them all:

  • Malfunctioning thermostats
  • Clogged air filters
  • Electrical ignition system/pilot light failure
  • Blower (fan) motor problems
  • Safety switch in front panel not engaged
  • Malfunctioning limit switch
  • Cracked heat exchangers
  • Gas line issues
  • Blown circuit breaker
  • Chimney exhaust or vents blocked
  • Intake pipe blocked or frozen over
  • Dirty drain lines
  • Furnace burners and/or flame sensor need cleaning
  • Poor airflow from gaps or obstruction in ductwork
  • Slipped belt or belts need replacing
  • Motor bearings need professional attention
  • Furnace has reached the end of its service life

Call Prompt Heating & Air Conditioning and we'll identify and fix the problem, whatever it is. Once your furnace is functional again, we’ll share any helpful pointers to keep the same thing from happening in the future, and to help your heating system run as efficiently as possible.
