Serving Westminster from Lafayette
Heating and air conditioning in Westminster, CO
Most Westminster homes were built before 2000, many of them during the city’s big growth years in the 1970s. That is a lot of furnaces and air conditioners reaching the end of the road, and a lot of repair calls we know how to handle.
Westminster is one of the bigger cities we serve, about 116,000 people across Adams and Jefferson counties at the 2020 census. We work all over it, from Historic Westminster around 73rd and Lowell to the neighborhoods near Standley Lake and up to Orchard Town Center at 144th and I-25.
Whether it is a no-heat call on a January night or a full furnace and AC replacement, you get the Nevin family and the same posted prices we charge everywhere.

What we see in Westminster homes
The city’s own records tell the story. Westminster went from about 19,500 people in 1970 to more than 50,000 in 1980, which the city calls the biggest growth period in its history, and passed 100,000 by 2000. Its 2018 energy plan found that about 87 percent of the city’s housing was built before 2000, and roughly 70 percent is single-family homes.
In practice that means a lot of homes on their second or third furnace, some still on original ductwork, and air conditioners that were added years after the house was built. 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. When a 1970s or 80s home needs both, it is often worth looking at a heat pump, especially with the rebates Westminster residents can use.
Historic Westminster is the old core of the city, and homes there can have older boilers, furnaces and swamp coolers. We work on all of them.

Westminster treats furnaces, air conditioners, heat pumps, evaporative coolers and water heaters, including tankless, as simple permits at the city’s Residential Counter. If you hire a contractor, the city requires them to be signed on to the permit. Ask anyone quoting the job whether the permit is included.
Xcel Energy is the main electric and gas utility in Westminster, and United Power supplies some electricity in the city as well. Westminster keeps an unusually good list of rebates on its Energy Efficiency and Electrification page: Xcel rebates for heat pumps and heat pump water heaters, state home energy rebates for income-qualified households, and Xcel Home Energy Squad visits. Amounts change, so check the program pages or our rebates page.

What an amazing and honest technician Sam was. He was very knowledgeable and thorough. Sam took his time and checked our furnace and AC/Heat-pump top to bottom. He put on shoe covers each time he came into our house. I will never use any other company to service our system. You need an honest and reliable company call Aspen Creek Heating and Air. Sam thank you for all you did.

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.

Very satisfied with our experience with Aspen Creek. Sam came out to evaluate our A/C system after another company in the area told us we needed a replacement part that would cost thousands of dollars. Sam took the time to thoroughly assess the system and let us know that the part was actually functioning properly and did not need to be replaced. He also gave us some helpful recommendations for improvements that could genuinely make a difference with our A/C performance, while being clear that they weren’t urgent or things we needed to spend money on immediately. We really appreciated his honesty, expertise, and straightforward approach. It was refreshing to work with someone we felt we could trust.

I can not say enough about my positive experience with Aspen Creek and the installation of my heat pump to replace my very old A/C. From the office staff Shannon and Danni helping me with my scheduling conflicts, to Sam giving my estimate and answering questions, and Charlie, Toby and Trevor coordinating the install, everyone was knowledgeable, professional, and friendly. Trevor was my HERO and made sure I understood my new system, showed me how to work everything and told me some things to watch for. It feels good knowing things were done correctly and I feel confident should I have any questions or issues, I am in good hands! Thank you Aspen Creek, I'll sleep well tonight in my cool house! 🤣

On possibly the hottest day of the summer around 5PM, our AC quit working. I had read several positive reviews about Aspen Creek Heating and Air on another social media site and decided to contact them. The phone was immediately answered by Dani (sp?). She was very professional and scheduled a service technician for the next morning. Sam showed up as scheduled, was professional, and didn't try to upsell us. He diagnosed the problem within 15 minutes. The charge was reasonable. We are so glad we found Aspen Creek Heating and Air and will definitely use them in the future for any heating or cooling needs. We highly recommend them.

We had Dan and Toby install a mini-split in our bedroom because our central air wasn't keeping the second floor room cool enough during the summer. The whole office was great to work with and they did an excellent job with communication and the install. There were a lot of twists and turns getting the lines routed down to the compressor/condenser and they did a great job of keeping it as clean and tucked away as possible. I highly recommend Aspen Creek.

Good honest company! I had a larger, well known company tell me I needed to replace my entire system for around $20,000 but then Sam and Aspen Creek came out and fixed it for $400! They even squeezed me in within 15 minutes since Sam was driving through from Golden. I definitely recommend them and we will be calling them from now on
Questions from Westminster homeowners
Do I need a permit to replace a furnace or AC in Westminster?
Yes. Furnaces, air conditioners, heat pumps, evaporative coolers and water heaters are simple permits at Westminster’s Residential Counter, and a hired contractor must be signed on to the permit.
Are there rebates for heat pumps in Westminster?
Yes. Westminster lists Xcel Energy heat pump rebates and state income-qualified rebates on its Energy Efficiency and Electrification page. Amounts change, so check the page. When we install a heat pump, Shannon applies for the Xcel rebate for you.
My Westminster home is from the 1970s. Should I replace the furnace?
Not automatically. Age alone is not the deciding factor. We look at the repair cost, the safety of the heat exchanger and what the system costs to run, then tell you straight. Our repair or replace page explains how we decide.

The same as everywhere we work. Repairs start with an $89 trip and diagnostic fee, waived if you go ahead with the repair.
