When your furnace fails to ignite, blows air but no heat, or is short cycling, we can help. A broken furnace can be an inconvenience when it’s chilly or a matter of life and death during Wisconsin winter months.
Whatever the reason your furnace is broken or underperforming, we’ll find out and explain what’s going on. We fix all types of heating systems, whether we did the installation or not. Whether you’ve got poor airflow from breaks in the ductwork or just routine wear and tear, our technicians are up to the task—and every repair job is backed by a 2-year workmanship warranty.
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?
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.
