Have you ever woken up to a cold, wet, snowy Denver morning only to find your furnace isnt working? Or how about going through a hot summer day without A/C? If your home heating or cooling system should break down or stop working properly, it is important to have a company you can trust to perform the heating or cooling repair services you need quickly, reliably and affordably.

Pasterkamp provided a competitive quote and did an excellent installation. Ken and Doug arrived on time and put down protection in the main floor hallway and basement stairs for the removal of our existing furnace and installation of our new furnace. I highly recommend them! Service: Heating system installation

I would never use them again. Unit installed 4 years ago now not getting cool never has gotten really cold after several visits to re-work duct work. THEN we call as our unit is not getting cold and they not only do not return the call, they say on their outgoing message that they will start charging you from the minute they start driving to your home.

Never again. As you can see, it took them 6 months to reply to this.and my biggest beef is that after 4 years the AC still does not get as cold as it should AND they begin to charge you from the minute they START TRAVELING to your home for a service call. A more palatable way to do this would just to charge a service call. You customer service is quite lacking.

They have inteligent and honest techs. The most frustrating aspect of working with Pasterkamp is you can't call and schedule an appointment! They always have to call you back. This leads to an annoying amount of phone tag. Service: Heating system maintenance

I would highly recommend Pasterkamp. We had purchased a house that had been converted from electric heating to an outside boiler system. The boiler went out in the first major snow storm, and we were without heat and hot water. To install a standard furnace/ac unit was not a straightforward installation. But their team spent the time to come up with a solution. Their installation team was friendly and did a fantastic job. We now have heat and hot water and a standard system. I cannot say enough good things about the entire team.

Dan, the tech, was a nice guy. Got on my roof for 30 minutes just look over the swamp cooler with me. Said it all looked pretty good. Told him I'd replace the float valve myself. Talked to Dan at the truck, bought $24 worth of parts, and he rang up my bill at $279. He was on my roof 30 minutes, but I was charged for an hour drive time prior to that @ $34 per 15 minutes IN ADDITION TO a $45 Trip Charge. Recap: $279, $24 in parts, 30 minutes looking at swamp cooler, no repair made. Had a personal chat with Dirk, he explained their billing and he found this bill justified--FREE MONEY.

I would never recommend or work with this company again. Everyone I spoke with was nice enough, but being charged $136 prior to even meeting the person at my house is ABSURD. I guess if the job before mine was right next store, I would have only paid $34 prior to meeting ole Dan.

We recently had a Mitsubishi ductless air conditioning system installed in our house and we are so pleased with the work performed by the nice people at Pasterkamp. We met with Jared, the residential sales estimator, who spent several hours with us answering lots of questions. He was so polite and congenial, and never rushed us to make a decision.

After we accepted his proposal, the units were installed 7 - 10 days later. Eldon and Aron and Ken, the electrician, got it installed and up and running in a day and a half. Not only were these guys knowledgeable and quick, they also cleaned up their mess each day. Needless to say, we love the air conditioning and give Pasterkamp a five star rating.

I've owned two homes and quite a few rental properties over the last thirty years and worked with a number of HVAC companies that just didn't meet my high expectations - and then I found Pasterkamp. They hire only the best, and it shows. Great technicians who have the answers to your problems, and great AC and furnace installations at a very fair price.

And I love the story about their family business. When Mr. Pasterkamp opened his shop he told his workers that the company's motto is "The Golden Rule" and for the last sixty years he and his sons have "treated people like they would want to be treated." The world is a better place when you have businesses, and families, who keep that rule top-of-mind.

We've worked with Pasterkamp twice now. The first time was for our boiler. We thought we'd need a new boiler, but the guy (who came immediately at the end of the day!) really knew what he was doing and changed a small part. This was two years ago and still going strong. More recently, they came right over and fixed or AC. Very prompt service, courteous and knowledgeable employees, reasonable prices. Strongly recommended!
