Gas furnace repair service

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.

All Reviews

Forced-air natural gas furnaces are the most commonly used residential (and light commercial) heating systems in our area. Prompt Heating & Air Conditioning provides expert, warrantied repair service for single stage, two-stage and modulating gas furnaces in all major brands.

If your gas furnace won’t start, keeps shutting off, blows cold air or is leaking water, call Prompt. We’ll identify the root of the problem and give you a firm quote for repair service and parts.

Oil furnace repair service

Oil furnaces are much less common than gas furnaces in the Milwaukee area, and we fix both. If your fuel oil furnace won’t start, the reset button keeps tripping, it’s not getting hot enough, or it’s making a rattling noise, just give us a call.

There are a few oil furnace troubleshooting steps you can try at home:

  • Is your themostat setting correct?
  • Is there fuel in the oil tank?
  • Are the valves open?
  • Is the chimney clear?
  • Could the noise be coming from loose access panels?
  • When’s the last time you had the filters cleaned?

Regularly cleaning and replacing the oil and air filters in an oil furnace is very important. We also provide oil furnace cleaning and maintenance and recommend at least a yearly tune up from a trained technician. If you see any oil lines leaking, hear loud knocking sounds or see soot in the burner chamber, call a professional for oil furnace service.

How much do furnace repairs cost?

Furnace repair costs vary based on the cause of the problem, how long it takes to repair and if any replacement parts are needed. Once we’ve diagnosed the issue, you’ll get a firm repair quote for the total price to fix your furnace. We understand cost is an important concern for our customers so we keep our pricing fair and explain the work ahead of time. No surprises!


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
  • 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.
