Gustafson Heating & Air Conditioning Inc.

Highly recommend Gustafson. Mike came out and provided a detailed estimate and scope of work. Their crew showed up on time and they were very careful to not to make a mess. Tarps were put down to ensure everything was kept clean. Install went great, and I couldn't be more pleased with the workmanship. You can't go wrong doing business with Gustafson!

They were scheduled to come out in 5 days to fix the AC in our new house we had just moved into. My mother in law that lives with us is going through chemo and the heat was making it even more difficult for her. They came out the next morning and fixed our issue. The technician was really nice and sincere. I would recommend them to anyone

I'm a developer in the Greenwood Village area and have been using Gustafson Heating & Air Conditioning for a couple of years now on both remodels and new builds. They are fantastic. Pricing is great, they are quick to get the job done, and the installers are nice people to talk to and have on site. We have passed every HVAC inspection since we have started using them. I highly recommend them.

Edited for grammar errors.

Update: we did have a partial pass only on a recent inspection due to errors made by the previous builder. No one can guarantee to pass every inspection but I think these guys have the best track record for passing out of all our subs.

I cannot recommend this HVAC company enough. They responded promptly to my initial request. Answered all my questions throughout the process. Had the most reasonably priced options out of three companies we called for estimates, as well as provided more service for that reasonable price. They were on time for installation, did a great job of installing and keeping the area clean. We had new furnace and AC system installed. On top of it-the new system works great and is quite. We are very happy!

First rate quality service, fair and reasonable pricing, very professional.
We had received 3 other bids and Gustafson was by far the most reasonable and responsive team. Mike supervised the team the whole time. Group of install guys were fantastic. Cleaned up everything, walked me thru operations of new furnace and air conditioner. Arrived on time, installed both furnace and air conditioning unit in about 6hrs. A+ recommendation and will have our business in the years to come.

I am very very happy with Gustafson's. This company was recommended to me by an inspector, but I'm not to keen on trusting a recommendation so called them and 4 other companies for new furnace and AC quotes. Not only did they quote me the best price they were very responsive always on time, even filled out the Xcell energy rebate form for me. I was beyond pleased with their service and products. I love my new AC!! Would highly recommend them!

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.

It started with the sale manager Mike. He was on time for our initial appointment to get an AC install (going from swamp cooler to AC). He walked us through what he was thinking, the size of unit we needed, location on the outside etc. Our house is 69 years young and the ducting was causing some issues. Mike explained his thoughts about best course to go. Unit pricing was in line with the competitors as well, but over all first impressions were key here. Mike was not "just" trying to sell us on something.
Day of install was Friday the 22nd of January (I know AC in Colorado's winter) the install team and Mike were parked outside waiting for the appointment time they were early. Both Mike and the installer walked us through again the plan with the duct work that needed done and what to expect.
Back story here, we just had our furnace replaced by company X with a variable speed unit that always sounded like a jet engine. Problem one, company X never wired the furnace right from the start the fan was always blowing at the highest speed it could. Mike explained to us the problem with that and the thermostat they installed.
Back to day of install, Mike came up with a solution that WAS going to cost us more money...oh crud he offered a solution to the fix with a new Thermostat that would handle the variable speed motor on our furnace at no charge....didn't expect that nor did we ask for that. He slash Gustafson did it on their own.
We had to have a new duct done to our basement as well. The install Frankie not only did it but mad it nice and tight without taking the easy way out he took the time to route it so it didn't take up room in an already crowded spot.
LONG story short, we cannot wait to try our new AC out this summer. We cannot recommend Gustafson enough. The whole team was very professional and they gained a new client for our HVAC needs. In our opinion you can not go wrong by hiring Gustafson!

We have been using Gustafson for many years and they have always been great! I called their 24 hour number yesterday - we had no heat! - Jeremy has done work for us over the years and called me within a short time. He determined that we needed a new blower fan. He gave me the option of coming out yesterday (Sunday) or this morning, we elected to tough it out until this morning. Jeremy called me early this morning and said that they got the part and Hugo was on the way. Hugo is a great technician who has been here before and had the unit repaired and heat on in less than an hour. 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 - which is a pretty highly prized attribute for anyone these days. I highly recommended Gustafson. Thanks again guys!

I would like to thank Gustafson Heating & Air Conditioning Team for an outstanding job installing my new Rheem heater and AC. Helping with equipment reviews, purchase agreement, installing, and handling of all the paperwork (permits, inspection documentation, equipment registrations, rebates).
Your installation team was on time very nice to work with at our home with an overall great attitude their workmanship and very professional gave us a feeling of quality, they worked well together and respecting our home caring enough to wear the blue shoe protectors whenever they entered our living areas to help with eliminate shoe marks on our floors and rugs.
We enjoyed the time your installation team spent working on our new system.
We certainly would recommend Gustafson Heating & Air Conditioning to anyone looking for HVAC installation or service.

Thank you, Mike and your Team.
