Frequently Asked Questions

We’ve answered some common questions homeowners have about heating services and furnace replacement.


Schedule furnace maintenance once a year. If your furnace hasn’t been serviced in over a year, it’s worth booking a visit even if it seems to be running normally. Our residential maintenance plans include HVAC visits, plumbing checkups, and electrical inspections. Visit frequency varies by membership, and you receive reports and photos documenting our findings, so you can see the condition of your systems.


Frequent breakdowns, rising heating bills without increased usage, rooms that stay cold, and heat exchanger corrosion can make replacement worth discussing. These problems may still be repairable, and no single symptom calls for a new system on its own. Most furnaces last 15 to 20 years, so we weigh your furnace’s age, condition, and repair costs to give you a clear recommendation. If replacement is recommended, our free estimate helps you compare that expense with the cost of further repairs.

“I would choose them again and again.”

Pasterkamp has installed heating and air conditioning systems in two of our Colorado homes. In both cases, the systems have worked flawlessly. This company is a Colorado institution. I would choose them again and again.

“James really worked hard to find a solution and I really appreciate his efforts.”

Both Teresa when I called to set up service, and James who came out to check our unit were very polite and friendly. James really worked hard to find a solution and I really appreciate his efforts. We finally got our AC working. I would very much recommend these guys. Thanks much.

“I was happy to speak to someone who really knows the products and tells you what you need and didn’t try to upsell me.”

Brandon was very easy to speak to, he told me exactly what will happen and when. I have already given my sister Pasterkamp's number! I was happy to speak to someone who really knows the products and tells you what you need and didn't try to upsell me. I will always use Pasterkamp from now on!! I am getting a furnace that's the right size for my house and a heat pump installed
