Highland, Sunnyside, Berkeley and beyond
North Denver has some of the oldest homes we work on, from 1880s Victorians in Highland to the postwar cottages of Chaffee Park. Old boilers, tight basements and add-on air conditioning are everyday work for us.
When people say North Denver, they usually mean the Northside: Highland, Sunnyside, Chaffee Park, Jefferson Park, West Highland, Berkeley, Regis and Sloan Lake, plus Globeville and Elyria-Swansea to the east. We work in all of them.
We also serve the unincorporated Adams County communities just north of the city line, like Berkley, Twin Lakes, Welby and Sherrelwood, which have Denver mailing addresses but sit outside the city.
The Northside is old Denver. The town of Highlands was incorporated in 1875 and joined Denver in 1896, and the Potter-Highlands Historic District alone covers about 700 buildings, from Queen Anne Victorians to Foursquares and Craftsman bungalows. Berkeley joined Denver in 1902, and Globeville in 1903.
Homes that old can have boilers and radiators, gravity furnaces long since converted, ductwork snaked through tight basements, and air conditioning that was added decades after the house went up. We work on all of it, and we will tell you honestly when an old boiler is worth keeping.
Chaffee Park is a different story: one-story homes built between 1945 and 1952, the first 412 of them reserved for veterans with children. Those homes, and the postwar houses filled in across Sunnyside, are usually on their third or fourth furnace. 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.
Common heating and cooling calls in North Denver, and where to start.
Repairs and replacements on the boilers still heating many older Northside homes.
Boiler serviceCentral air, mini-splits and heat pumps for older homes that were never built for them.
Air conditioningInside Denver city limits, furnaces, air conditioners, evaporative coolers, boilers and water heaters in single-family homes and duplexes can be permitted through Denver’s quick permits. Denver also requires contractor licensing through Community Planning and Development. If you are comparing quotes, ask whether the permit is included. Outside the city, in unincorporated Adams County, permits come from that jurisdiction instead, and we will sort out which applies.
Xcel Energy provides Denver’s electricity and gas. For heat pumps, Denver has offered its own Climate Action Rebates through the Office of Climate Action, Sustainability and Resiliency, on top of Xcel rebates. Programs and amounts change, so check the city’s program or our rebates page.

I had a furnace inspection from Aspen Creek. The technician was thorough, professional, and explained everything that he was doing. The appointment was easy to set up. I would definitely call this company again for HVAC issues.

Today’s service was the yearly furnace inspection. The technicians arrived within the quoted time window, and were friendly, informative, and knowledgeable. The pricing was competitive. This is the second time that I’ve used Aspen Creek, the first time was for air conditioner repair. I’ve been completely satisfied so far, and plan on continue using them for my HVAC needs.

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.

⭐⭐⭐⭐⭐ 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
