Stuck with a heat pump nobody will touch? Let’s get you unstuck.

Maybe you’re halfway through your own install. Maybe it came with the house. Maybe it quit and your installer stopped answering. Wherever you’re stuck, we’ll measure what’s there, tell you plainly what we find, and help you get to reliable service.

Why we do this: We know what it’s like to be left with someone else’s install.

Heat pump PATH program

Program for Adoption, testing, and help

Our cofounder started Just Heat Pumps after living with a heat pump the professionals got wrong. He spent months diagnosing and fixing it himself, and decided homeowners deserved better. Heat Pump PATH exists for the people who call us in that same spot.

We don’t judge how you got here. We measure, we explain, and we tell you what we can and can’t do before you spend money.

You did the reasonable thing, and you’re still stuck. Why we can help:

  • EPA 608 certified: Licensed refrigerant work, done by our own technicians.
  • ICC G29 Master Mechanical: Code knowledge behind every exam.
  • Led by a PhD Physicist: Dr. Xerxes Steirer, PhD in applied physics and CoFounder.
  • NATE Certified: Heat pump installation credential.
  • BPI Certified: Energy auditors, so we see the whole house as a system.
  • Heat Pumps Only in Colorado: It’s all we do, across the Denver Front Range.
Working late to make sure the heat pump works before sundown!

Our experience with Just Heat Pumps was outstanding. Xerses and Erin, other JHP staff, and their contractors for installation and electrical work were very skilled, professional, and conscientious. It’s just over a year that JHP installed mini split wall and ceiling units in our home. During one of the hottest summers in Colorado history, we stayed super cool. We used the heat feature as a supplement to our hot water heat system in the winter and the house was uniformly warm and comfortable. We also had our annual service inspection, and the system was thoroughly checked and cleaned. Before we chose JHP, we met with several companies to find they were pretty good sales people, but short on technical knowledge and unable to solve a few workarounds that we needed. We chose JHP because they had the tools to right size our units, make helpful suggestions, and genuinely knew the pros and cons of various options. We have been so pleased with Just Heat Pumps and would not hesitate to highly recommend this awesome company.

We got our annual tune up on the system. Everything is in good shape. Kevin was our service technician and he was terrific! He was polite, courteous and friendly. He answered my questions and explained why the fan periodically activates when the system is "Off". This is a great local company with great design and service. They have my wholehearted recommendation for their products and services. Thank you Xerxes, Erin and Kevin - you do a great job.

Complementary maintenance service to clean the outside unit, check out the system, and answer question. Everything is working great and glad to have the Just Heat Pumps team taking care of it all.

Just Heat Pumps replaced our furnace with a heat pump and was fantastic to work with through the entire process! They were prompt, professional, transparent, and friendly. Xerxes takes a data driven approach to specifying the best system. The installation team even asked if we wanted to write anything in the concrete pad they poured for mounting the condenser, which our daughters loved!

Working with Just Heat Pumps LLC was a 5-star experience all around. Their depth of knowledge on modern heat pump systems, efficiency ratings, and local Denver incentives set them completely apart from traditional HVAC outfits. The installation was handled on schedule with meticulous attention to detail and clean workmanship. Our home stays perfectly comfortable, and the system is remarkably efficient and quiet. Highly recommend them to anyone making the switch to an all-electric heat pump setup!

Wow! Just Heat Pumps replaced my aging HVAC system and I could not be happier. From the initial design of the system to the completion of installtion and county inspection, Xerxes and his team of pros made a complicated job turn-key. Justin gets a special shout-out as the point person on the installation. The process of removal, installation, electrical takes a few days and everyone communicated above and beyond to completion. I highly recommend Just Heat Pumps!

My old furnace was 26 years old. It still worked, but its motherboard was outside of where it was supposed to be. It had been MacGuyvered by the last furnace repairman in 2019, who told me that the warehouse that kept Lennox replacement parts for their older models had been flattened by a tornado, so the older parts were no longer available. Today, I have a heat pump installed. The outside unit is so quiet that I can barely hear it from the back door, about 15 ft away. The installers just left about 30 minutes ago, and the temperature has already dropped 1°F. Plus heat pumps are far more energy efficient than regular furnaces, gas or electric. If you're in Denver metro and are looking for this same change up, may I recommend Just Heat Pumps? The company is owned by someone I used to work with at NREL, so I knew they'd be ethical. Their installers were wonderful at wrangling around my five cats, were on time, and worked hard and professionally over the course of the two-day installation.

Really great experience with Just Heat Pumps installing a 4-zone heat pump at my townhome. They were great communicators throughout the entire process and completely transparent. This business actually cares about their customers and I can't recommend them enough.

I sensed a high degree of professionalism from the start. Our finished basement can be uncomfortably cool and our garage can get really hot in summer. We did a mini split in both locations. Did try the basement one last night, so effective and quiet. The poured in place pad for the unit outside is impressive. All the people we had contact with were outstanding and all were willing to go out of their way for the customer. Special accolades to our installers Ben/Ryan for an amazing job!

Some of Our Heat Pump Work

Find Your Starting Point:
One Program, Three Ways In

Our HVAC & Energy Certifications

We Can:

  • Tell you before the visit whether we can source parts, once we see model numbers.
  • Measure and document your system’s condition.
  • Stand behind the work we do, from the day we do it.
  • Source and repair these makes: Daikin, Fujitsu, Bosch, LG, Mitsubishi, Quilt, and some others by model.

We Cannot:

  • Warranty work we didn’t do. The original installer stays responsible for their installation and startup.
  • Promise parts for every brand. For some, your manufacturer warranty part is the only path.
  • Offer a care plan on every system. It depends on your equipment and exam results.
  • Work on unlisted or used equipment beyond a written report.

Small Problems Don’t Stay Small in a Heat Pump.

If it waits:

  • A slow leak or a marginal vacuum becomes a failed compressor, which on many units means replacement.
  • The first cold snap finds the problem for you, when every company is booked.
  • Nobody has a record of what was true, so every question turns into a guess.

With a PATH:

  • You know exactly where your system stands, in writing.
  • Your system is tested at full output before winter, not during it.
  • You have a local team that knows your system and answers the phone.

Common Questions

We try to answer the most common questions you might have about our PATH program. Check out some of these below, and contact us if we didn’t cover it!

Yes. We record what you tell us without judgement, test the system, and explain where it lands. Systems with owner refrigerant work can reach Verified, and a rebaseline can take them to the top tier.

It can. If your installer still offers a labor warranty, contact them first. We’ll ask about this on the screening call and have you sign an acknowledgment before any invasive work.

It holds the heat pump technician’s time and is credited to your visit. You get a written report either way.

Yes, as long as it’s UL or ETL listed. We can still examine it and repair it using your manufacturer warranty parts. We’ll tell you on the call that a care plan isn’t offered for that brand.

Adding refrigerant without finding the leak means paying again in a few weeks or months. We find the leak, fix it, and charge by weight to the ounce.

We currently serve the Denver Front Range. If you’re outside our area, we’ll try to point you toward someone who can help.

Ready When You Are. Tell Us Where You’re Stuck.

A short screening call is the first step. You’ll know what we can and can’t do before anyone comes out.

Have these ready for the call:

  1. Photos of the nameplate on the outdoor unit and each indoor unit.
  2. Who installed it, and roughly when.
  3. Where the equipment was bought, and whether the warranty was registered.
  4. Who made the connections and who opened the valves, if you know.
  5. Any vacuum readings, photos, or error codes you have.

Call us at 303.525.HEAT (4328)
