Next door to Lafayette
Louisville borders Lafayette to the southwest, so we are close by. Most Louisville homes went up in the 1980s and 1990s, and hundreds were rebuilt after the Marshall Fire. We know both.
Louisville is one of our closest neighbors. Like Lafayette, it started as a coal town, Louisville in 1877 with the Welch Mine, and became a suburban community after the mines closed in the 1950s.
We repair and replace furnaces, air conditioners, heat pumps and water heaters all over town, for families in Old Town homes, 1980s and 90s neighborhoods and brand new rebuilds alike.
Louisville grew fast after 1970, from about 2,400 people to more than 12,000 by 1990. A 2013 city market study, using Census data, found about 35 percent of the city’s homes were built in the 1980s and another 30 percent in the 1990s. Plenty of those homes are still running original or second-generation furnaces and air conditioners. Most gas furnaces last somewhere around 15 to 20 years and most central air conditioners around 12 to 15, depending on how they were installed and cared for.
The Marshall Fire on December 30, 2021 destroyed 550 homes in Louisville, according to Boulder County, and by August 2026 the city reported that 532 of them had been rebuilt or had started rebuilding. Most rebuilds were permitted to the 2021 energy code or better, so they tend to have tight, efficient construction, high-efficiency furnaces or heat pumps, and ventilation systems that need regular filter changes and care.
In Old Town, the historic core, we find older homes with furnaces and water heaters squeezed into small spaces, and the occasional boiler.

No heat? Start hereGoing electric? Louisville has its own heat pump permit rules. We will walk you through them.
Heat pump optionsLouisville has its own furnace, AC, water heater and heat pump permit. A furnace or AC needs a contractor with a mechanical license, a water heater or boiler a plumbing license, and a heat pump both mechanical and electrical. High-efficiency direct-vent appliances need a vent pressure test, and every permit gets a final inspection. Contractors also need a City of Louisville contractor license.
Xcel Energy provides Louisville’s electricity and gas. For heat pumps and heat pump water heaters, Boulder County’s EnergySmart program offers rebates and advising, and the county notes Louisville residents may qualify for additional city rebates. Amounts change, so check the program or our rebates page.

Our AC unit broke overnight. We found Aspen Creek through reviews online. Dan from Aspen Creek was out the next morning within hours of our call. He had us fixed super quickly and was just the nicest guy. He is super knowledgeable and I highly recommend his company.

⭐⭐⭐⭐⭐ Aspen Creek Heating & Air has been my go-to HVAC company for quite a while, and they continue to earn my business every time I need them. They are quick to respond, dependable, and professional. One thing I especially appreciate is their communication—they keep me updated throughout the process, so I’m never left wondering what is happening or when something will be completed. When there’s a problem, I want a company that responds quickly, communicates clearly, shows up when they say they will, and gets the job done right. Aspen Creek Heating & Air has consistently done exactly that for me. It’s difficult to find service companies you can truly rely on, and once you find one, you stick with them. Aspen Creek Heating & Air is that company for me. I highly recommend them to anyone looking for a reliable, responsive, and professional heating and air conditioning company. ⭐⭐⭐⭐⭐ #captjimandadela #capjimed

Aspen Creek has to be the most professional Company I’ve deal dealt with in a long time. Our repairman, Sam was on time, very professional, explained what was wrong and not wrong with our air condition unit. Sam was not the typical high-pressure salesman. I highly recommend Aspen Creek if you are having problems with your air conditioner or your heating.

Great communication, fast scheduling, reasonable prices (given the cost of HVAC stuff). Helped with a repair on my AC unit and got me in next day after a Sunday call with no rush scheduling cost. Thanks!

They showed up, were super friendly and professional, and fixed my issue quickly. Since this was more of a patch and I'll likely need a new AC system installed in the next couple of years, they gave a discount on this maintenance as well. Safe to say they'll have my business again next time I need it!

I called Aspen Creek after a conversation with my neighbor, who had just had a really positive experience with them. They came the same day and did complete testing on my AC system. My coolant level, combined with a dirty compressor had severely limited the air flow. Trevor walked me through precisely what was diagnosed, showed me the issues, completely cleaned out all four sides of our compressor and filled us up with coolant. My AC went from barely running to working smoothly and efficiently. Great company and response time and a pleasure to work with.

Always prompt and courteous. Took the time to explain what was going on and got it taken care of quickly.

Great service! My heating went out and a service tech was able to come out within a few hours. They diagnosed the problem and was able to get everything fixed without any problems. I'm so grateful for the wonderful help and customer service!

Aspen Creek was recommended to me by a friend who has used them multiple times. I would recommend them a hundred times more. They were quick and effective, no nonsense, just get the job done. And they are friendly with excellent customer service. They offered to bring additional space heaters since our furnace went out while temps were in the single digits. Such a kind gesture! I was panicking about pipes and people staying warm enough in the only cold snap of the winter, and they just took care of it all.
Yes. Louisville has a specific furnace, AC, water heater and heat pump permit. The contractor needs the right Louisville license for the equipment, and every permit gets a final inspection.
Newer, tighter homes usually have high-efficiency equipment and mechanical ventilation. They run best with clean filters, clear vent and drain lines, and a yearly inspection. Our tune-ups cover all of that.
Yes. Boulder County’s EnergySmart program has heat pump rebates, Louisville residents may qualify for more. Amounts change, so check the program or our rebates page.
The same as everywhere we work. Repairs start with an $89 trip and diagnostic fee, waived if you go ahead with the repair.
