How can we help?

We bought a new Rheem system in September 2018. I’m retired and I had plenty of time to get 6 proposals for our new HVAC system . My furnace and AC had reached 25 years of use. While doing research I found that a quality installation contractor is the most important single factor. The presentation, knowledge, and quality Rheem product Mike presented was superior to all others. The price was more than competitive. The installation of our new furnace and air conditioner was well done and the system is significantly quieter than our old system. We went with the 80% efficient 2 stage and variable speed fan. Mike recommended a unit of somewhat smaller BTU than our previous and as I write this its 25 degrees outside and the house is toasty in all rooms. I’m completely pleased with the service, quality, and price Gustafson furnished. I would definitely use them again. I suggest you talk with Mike before you commit to anything else. You might even save some money as we did!

Was trying to decide what company to go with for new furnace and central air conditioning installation. Called around to 6 different companies, Gustafson heating & ac was among the best price with the best available equipment (rheem, Bryant etc.) When Mike came out to our property in Aurora, co. He provided us with insight to the whole process that would be required. He also noticed the electrical panel only had room for one more slot which would have been the air conditioner, so he recommended we upgrade that as well. He was able to get us a quote for the whole project to include electrical panel replacement. Mike was able to have his guys work around my schedule because I had upcoming surgery. The lead project manager Hugo and Jacob were very helpful and knowledgeable, they did not mind taking time to answer any questions we had. They completed the furnace install/replacement in around 6 hours. They also removed all the old parts/pieces from the old furnace. Upon completion of the entire job, Hugo ensured the furnace was working as it should be and made sure we were aware how to operate the thermostat. The Air conditioner was put through many tests to ensure it would be running at peak performance throughout the summer. 2 days after completion of install of a/c, furnace and electrical panel. Aurora inspectors came out to our residence to make sure everything was done correctly and completely. The inspectors stated “whoever did this for you did a really good job, I see no issues at all.” Needless to say, I highly recommend Gustafson heating & AC to anyone in the market. These guys will make it worth your while. Mike thanks again for always keeping me in the loop about details and what was going on. You guys are awesome.

Mike McCartney helped me figure out what was the best fit for my home. He is extremely professional. Professional team. Mike walked me through everything. I am very happy!

I’m incredibly impressed with Tom and his team!  I had surgery and when I returned home it was 80 degrees upstairs.  They had my air conditioner up and running within 24 hours!  Thanks for the great work you guys did!

I have been using this company for over 10 years.  They installed an AC, humidifier and worked on my 20 year-old furnace.  They are professional, honest and knowledgeable.  They are half the price of most other places in town and the quality is beyond reproach. As the other reviewer noted they will do almost anything to save you money.

Jeremy is the best, he has saved us on this freezing day!

The absolute BEST service ever. Family owned. Everybody is super friendly and helpful. As long as I live in CO, they will always be my heating and air company.

Amazing service! I called Gustafson at 7 in the morning after my heater stopped working in the middle of the night. It was 3 degrees out and the forecast was calling for 6 days of the same. I have two young kids and a space heater got us through the night, but was unable to keep up. By the time I got them to school, the house was down to 40 degrees. I expected I would have to call a long list of heating and air companies to find someone to charge me emergency rates to come out the same day, being the first real cold snap of the year. They were my first and last call. I got their number from a sticker on the unit from the original installation, found them to open and answering the phone by 7am, and had an appointment for the same day in no time. They were able to get to my house right on time, diagnose the issue, and pickup and install the part in about an hour. The cost repair was very reasonable with no surprise “extras” The house was warm by the time the kids were out of school and we have been comfortable in the recent sub-zero nights.

I am a Real Estate agent and many of my customers have used Gustafson’s.  Many times we have short deadlines and Gustafson’s is always very good about getting a tech out to the property ASAP.  Lee is amazing, friendly, prompt and informative.  They stand behind their work and are competitively priced.  I would highly recommend this company.

Central air decided to conk out right before we left town. Called three different providers at 7am–one never returned my call, one could come at 4:30, but would have to charge me double time portal to portal (so I would be paying for his commute home), and finally Tom said he could come out that morning.  He came, had the part (I diagnosed it ahead of time), and had it fixed in about 15 minutes. Great experience.

Lee & all staff (especially Luz) are extremely responsive & go above & beyond to be professional and courteous.  I’ve had 3 service calls in the past 3 months (a new build house – all different unexpected scenarios) & they’ve consistently assisted & resolved the issue on the first trip.  Really appreciate their professionalism & top notch attitude.

We’ve been using Gustafson since buying our new home in 2011 and they have always been great to work with. We had an issue with one of our AC units yesterday and I called Gustafson, expected a several day wait, but as always they came through much faster than expected.  Robert was here this morning and everything is working like new.

Great job (again!)

Over the years, Gustafson has done quite a bit of work for me. They originally installed heaters (2) in my home 14 years ago, returned to do some duct work when we finished another part of the basement, installed a heater in a rental unit, and just this week installed an air conditioner in the same rental unit. They are wonderful to work with, and I trust them to do an excellent job for a fair price. I certainly would use them again and would feel very comfortable recommending them to others I know.

Great Service

We have been using Gustafson for years and they have always been great! I googled them on Saturday to get their number instead of going downstairs again where it is posted on our furnace. I was disappointed to see the negative reviews right away – that has certainly not been my experience and we have been using them for about 10 years now. I called on Saturday and left a message, “my AC fan is making terrible noises”! I got a call back within a half an hour and after a couple of questions they thought it would run until Monday – and they would have someone out to check it out Monday. Saved a technician their Father’s Day weekend and me some money, I am sure – and it did make it through the weekend. Jeremy just left and we have new energy efficient indoor motor blower. The bearing on the original one was failing. They have done work for us including installing the HVAC when we finished our basement. It is my experience that they do exactly what they say they will do and they charge a fair price to do it. Highly recommended.

Jim

So far very happy.

Great service and products. Everything as promised.

Happy Owner

Great service.

Very nice and professional staff. Did a great job!

Keith

Highly competent and personable.

Robert arrived right on time. He was friendly and easy to get along with. He solved our furnace problems, explained why they happened and how to avoid them in the future. Seemed highly knowledgeable and willing to share information with me. I felt confident in his work.

What a Great Company

Everyone from Sales Representative Mike, to Jacob and other installers they were all fantastic, we had a furnace put in a few months ago, and they were great and very competitive on pricing, we used them again to install a humidifier, and a few weeks later for a gas line installation. They are great and very professional and courteous of your home, and the salesman went above and beyond helping us in anyway. Highly recommend.

WOW, what a great job Gustafson Heating and Air Conditioning did for my wife and I. They were professional, fast, and way less expensive than the others we looked into. We really appreciate what they did. It was in the winter when our furnace broke down and they replaced it immediately. They left our home clean and warm and we will appreciate the cool air this coming summer. THANK YOU Mike and your team!

Kristina C.

I received a number of quotes to install a whole home humidifier. Gustafson was amazing from start to finish. I was able to handle everything over the phone without needing an additional in-person quote with a number of upcharges. I spoke to a gentleman who walked me through options by seeing pictures of my setup and was extremely knowledgable on what was necessary to ensure I was getting the correct humidifier for my home. The pricing was extremely competitive compared to the others and was not full of hidden charges. When I called, they were able to get an appointment set up within a week. The service tech was on time, courteous, cleaned up after himself, and walked me through the whole setup.

Svein R.

I got three quotes for a heat pump and gas furnace back-up. Gustafson’s was the most competitive. In addition, Mike McCarthy was, and is, a gem; very knowledgeable and responsive. The other Gustafson employees on the job were courteous and professional. I am very pleased with the equipment and the installation, which was a difficult one. I highly recommend Gustafson!

Meagan P.

Gustafson installed our HVAC system in 2019 and have been so great with service! They’re honest and back up their work. Recently our A/C wasn’t cooling to the set temp. Todd was so kind & diligent in teaching us what to do as homeowners, but also servicing/cleaning the mechanics and we’re back to a nice, cool home just in time for higher temperatures!

Scott H.

Purchased a mini-split (AC / Heat Pump) unsure if I’d be able to install it or not. I installed most of it myself but there were a few technical procedures I didn’t have the expertise or tools to undertake. Dillon came out and finished the job, doing top-notch work and taking in account the aesthetics of the unit inside and out. Very reasonable price as far as I’m concerned. My new go to neighborhood HVAC company.

David R.

Basement flooded. This is where my WFH office is, so it was a big deal. Gustafson sent out Todd to fix it. He got it fixed quickly, and charged me a very reasonable fee. Basement is warm and dry now. I can’t say enough good things about Gustafson.

Steven B.

The technician “Luis” was fantastic as usual. All the services and technicians we have used with Gustafson over 12 years have been prompt, professional, timely and reasonable over the years. I definitely approve of this vendor!!!

William R.

Our furnace went out and our regular company gave us a 2 week window for coming out. We have a RHEEM furnace and needed an authorized RHEEM dealer. I called Gustafson and they came out in 48 hrs. They were so nice and the technician –Dylan–was so helpful that I am switching companies. Really a great experience.

Sonja L.

Absolutely the best!!!! This is an honest company with very professional people working for them. The price for all work is always very fair and very reasonable!!!

Krista B.

I had the whole HVAC system installed by Gustafson about three years ago and recently requested maintenance on the system. Technician Robert Gomez was the tech that responded and he was very personable, easy to talk to, and explained what he was doing to me to service my furnace. I felt like I received thorough service and he provided advice for the future as well. Thank you, Robert!! I hope to be able to request you again in the future to do maintenance on my AC next spring.
