Elijah RomeroThere’s nothing like having a quiet, cozy home while the Colorado wind howls outside. But that peace disappears fast when your furnace starts making a loud thumping noise.
Since we live in the Mile High City, our heating systems have to work extra hard through long winters. When your vents suddenly blow cold air, or the thermostat won’t listen, you need an HVAC technician who really knows how high-altitude systems work.
We’ve been through winter emergencies like this and know how stressful it is. So after checking out local experts and how quickly they respond, we’ve listed here the best furnace repair services in Denver that you should call!

1. Golden West Plumbing, Heating, Air Conditioning, and Electrical
Website: https://www.goldenwestph.com/
Address: 4217 Delaware St.
Contacts: +1 303-433-6077
Hours: Monday – Sunday, Open 24 Hours
Golden West Plumbing, Heating, Air Conditioning, and Electrical is a family-owned Denver company known for never charging overtime, even if your furnace breaks down in the middle of the night.
That kind of policy is a huge relief if your heat stops working at 2 AM on a weekend.
They’re also great at finding tricky electrical problems that other HVAC crews sometimes overlook. Several of their previous clients said their technicians are extra careful about checking for carbon monoxide leaks, which made them feel a lot safer.
Another client shared that their tech, Josh, found an installation mistake from another company that had been making their system less efficient for years.
People really trust them, and it shows in their A+ rating with the BBB!
Sadly, a few customers have said their quotes for full system replacements can be higher than what smaller shops charge.
Customer Reviews
He showed that he really cared and was very professional
Jason was fantastic. He took the time to carefully diagnose what was, at first glance, a simple fix on our boiler. After investigating thoroughly, he uncovered a mistake made during installation and got it fixed the next day. He showed that he really cared and was very professional. Great experience.

He was on task, tidy, and friendly
Carlos was wonderful. Scheduling was easy and I was surprised they could get someone out to my house on a cold weekend when I knew they were busy. Not only did he diagnose the problem promptly but we had a solution within an hour and restored heat by dinner time. He treated our home like his now. He was on task, tidy and friendly. Very professional and trustworthy. We won’t use anyone else!

Website: https://servicebyheart.com/
Address: 646 Bryant St.
Contacts: +1 720-442-0474
Hours: Monday – Sunday, Open 24 Hours
Heart Heating, Cooling, Plumbing & Electric stands out by offering a lifetime warranty on all repairs as long as you stay on their maintenance plan.
Their “Heart Protection Plan” is a great safety net if you’re busy and don’t want to stress about your furnace breaking down again.
We’ve also learned that they text their clients a photo and bio of the technician before they arrive, so you always know who’s coming to your door. They really focus on their customers, often waiving service fees if they end up repairing.
Just remember, their initial diagnostic quotes can be higher than average before discounts kick in. They’re also very thorough, so what starts as a quick checkup might turn into a two-hour deep look at your whole system.
Customer Reviews
He fixed the issue quickly and courteously

3. Brothers Plumbing, Heating, and Electric – Denver
Website: https://www.brothersplumbing.com/
Address: 6201 Broadway
Contacts: +1 303-451-5057
Hours: Monday – Sunday, 6:30 AM – 8:00 PM, Sat-Sun: 7:00 AM – 8:00 PM
Brothers Plumbing, Heating, and Electric is well known for their “win, win, win” attitude and flat-rate pricing, so you’ll only pay by the job, not by the hour. This takes away the stress of worrying about a technician dragging out a repair while your bill goes up.
They do a great job of explaining exactly why a repair is needed, which is perfect if you want to understand how to take care of your system.
Their technicians are background-checked and always act professionally, even when things get busy during the coldest months.
One of our colleagues used Brothers for a water heater repair. He highlighted that their two-hour appointment windows were the most reliable in town!
The only drawback is that they close at 8:00 PM, so they’re not available all night. On a good note, they do work weekends without charging extra fees.
Customer Reviews

4. Controlling Systems Heating, AC, and Electrical Repair
Website: https://www.controllingsystemsco.com/
Address: 7000 N Broadway #1-106
Contacts: +1 720-782-1658
Hours: Available 24 hours
Controlling Systems Heating, AC, and Electrical Repair has been helping homeowners since 1976. Since then, they’ve been known as a Ruud Pro Partner, so they really know their stuff when it comes to certain furnace brands.
They’re especially skilled at dealing with tricky ductwork in older Denver bungalows.
We talked to a homeowner in Wash Park who was impressed with how they installed a high-efficiency unit in a small, tough-to-reach basement without taking any shortcuts.
Something else we appreciate is their “no gimmicks” policy, where they’ll give you a quote and that’s exactly what you’ll pay, with no surprises. They also give you a solid two-year parts and labor warranty on repairs!
Sadly, some longtime clients mentioned that their scheduling can get a bit busy during peak seasons, which can mean a longer wait.
Customer Reviews
I can’t recommend them enough
Vincent serviced our furnace and took all the precautions to make sure it was ready for the winter! Very personable, explained the issues and tips to make sure it’s running efficiently. For the value of the visit, I can’t recommend enough!
- Jon Kenney Google Review
Controlling systems is our go-to for heating and cooling
We have used controlling systems for a few years and they are always so professional and honest which I feel like is rare these days. They let you know when they are on the way and it’s often ahead of schedule which I appreciate. They wear booties in the house and talk you through the service. Controlling systems is our go to for heating and cooling!

5. Cool Sunshine Heating and Air Conditioning, Inc.
Website: https://www.cool-sunshine.com/
Address: 4395 Oneida St.
Contacts: +1 303-287-1846
Hours: Monday – Friday, 7:00 AM – 8:00 PM
With over 60 years of combined experience and an A+ BBB rating, Cool Sunshine is a trusted name in Denver. You can count on them to answer your follow-up questions quickly, which shows how much they care about their customers.
One thing we really like is how honest they are. We’ve heard that a tech named Aldo actually saved a client thousands by finding a simple blown fuse, even though another company said the whole furnace needed replacing.
And while they specialize in Lennox systems, they’re really knowledgeable about all brands.
They’re also known for being super clean, always leaving the workspace better than they found it, even sweeping your garage after a furnace install.
On the downside, Cool Sunshine is closed on weekends. Also, they mostly handle residential projects, so they might not be the best pick if you manage large commercial properties.
Customer Reviews
Always very prompt, professional, and willing to explain the fix and options
Sunshine is so wonderful to work with. When our furnace wasn’t working, they came out within an hour of calling. Unfortunately, the furnace stopped working again the very next day and they were out within 30 minutes of calling. Always very prompt, professional, and willing to explain the fix and options. Thank you!!!

Wouldn’t hesitate to recommend them to anyone

Over all super pleased with the work performed and wouldn’t hesitate to recommend them to anyone!
