Audy and his team took immense pride in making sure this job was done in a reasonable time and explaining all the things that were changing with the new setup. This is my second experience with this company and I appreciate how Audy runs the team. My father didn't realize what a difference it would make getting AC in the house I grew up in when there was no AC unit. I don't have to worry that the house will get too hot for him during these Colorado heat waves. This team went above and beyond and I hope it continues on for future customers.

I was put on the schedule for the next available appointment and also given tips over the phone by Audy that might resolve my issue myself. And it absolutely did!!! no appointment needed. It's rare to find that level of service and support. You have earned a loyal customer. I will definitely be calling again for all my future HVAC needs.

I got the recommendation for Controlling Systems through ChatGPT and they didn't disappoint. The sales process best of the bunch. Chris, our sales rep. took the time to do a manual J measurement throughout the house to ensure we were getting the right system for the house, which none of the other contractors even considered. After showing me all the options, we went with their RUUD top of the line system which came with a multi stage furnance, variable stage AC, and a heat pump. They applied the rebates offered by Xcel, so we didn't have to wait for the rebates, we just signed over the rebates to them during the sales process. The installers were top notch, kind, and ensured they took good care of our home. I couldnt be happier and highly recommend them. From a price point, they came out thousands less than the closest competitor, and I'd note the closest competitor wasn't willing to do a transfer of the rebates. We would have had to claim those after the sale.

There was a slight deviation from the equipment in the quote and what was installed and I wasn't even worried. Three weeks later I got a call that they had the part and they installed it!

They responded to my quote request within an hour and made scheduling easy. We contacted several other companies, but they were either more expensive or couldn't come out until the following day. Efficient Comfort was able to come the same day, diagnose the problem, and fix everything at a very reasonable price. The entire experience was smooth from start to finish. Their responsiveness, professionalism, and fair pricing really stood out. I highly recommend them to anyone looking for reliable HVAC service.

Mark showed up on-time and was very personable and professional. I know it seems trivial, but a clean pressed uniform, eye contact and a firm handshake mean something to me. He explained the plan before starting. He showed me before & after photos when he was done and made recommendations for future work without trying to upsell the call. I really appreciate that! I ended up signing up for the Maintenance Plan which has them come back twice a year because this is the type of company I want to do business with. Would definitely recommend True!

When people go above and beyond, they deserve the recognition…read more In all transparency, True Heating and Cooling had done previous work on our tankless water heater for the past couple years - mainly just a normal maintenance. All good work, but my quibble was follow up on some outstanding issues (mainly with a knocking noise that they didn't seem to get to the bottom of and didn't follow up) which led me to explore other companies - which unfortunately were no where near as detailed or close (actually most further) from a solution and I came them another chance and I'm glad I did. Justin helped work through some more detailed troubleshooting and provided a solid quote (detailed and quick) for solutions in a quick manner. He listened and cared. He was knowledgeable and thorough. While not only getting the issues I had resolved, was also able to resolve other code and safety issues that stemmed from the original install of the boiler. I would highly recommend True to others and will also recommend to other neighbors within my condo complex that have similar setups and might need work. Thank you both Justin and Logan - appreciate the work. (It's also interesting that they are not listed on Navien's website or BBB accredited; this is where I looked for contact information for service as they a) certainly can work / service Navien products well and b) should deserve to be accredited with BBB. Other companies that I've consulted were on both sites and didn't provide as good of service)

My wife is in Hospice care and I am 73 years old. I accepted the estimate thinking that it must be a complicated job. I also didn't want to have a parade of plumbers inspecting the problem to get multiple quotes. I also feared the pipes could burst soon, so I felt a sense of urgency. But I accepted the estimate. One hour and 15 minutes into the job, the plumber told me the job was done. I was surprised and angry. I asked him if they always charge $600 PER HOUR ( I included some travel time in the calculation).. He told me he doesn't set the prices. I called the company told them my thoughts on pricing and asked for the owner to call me as I didn't want to blindside him with a bad review. He/ she never called back. This is the first negative review I have ever written and do not do it lightly. DO NOT US THEM IF YOU WANT A FAIR PRICE.

One of the others (Tnt Mechanical) scheduled first, and arrived in a black pickup truck with no identifying information, no uniform or company logo shirt, no business card. The number of scammers in our neighborhood is on the rise so I said no thank you and asked him to leave. Then Bluestar called me to set up a time; when they arrived it was more as I expect from a trusted business: company van, company uniform, business card, etc. Ivan was very friendly, knowledgeable and professional. He found a coolant leak in my system within minutes, showed it bubbling through leak detector fluid, and wrote up an estimate to repair the leak plus recharge the coolant. With a discount for cash, it was a very reasonable price and I agreed. He went to work right away. About an hour later he'd finished and took me around to inspect what he'd done, explaining everything. This really helped me feel at ease with the quality of the work, and that nothing had been done that wasn't necessary. He even helped show me some things about my furnace that I had questions about, not related to the AC work. Ivan responded quickly, got us repaired quickly at a reasonable price, and left me with feelings of trust and satisfaction. Next time I have any problems with my furnace or AC, I'll know to call Bluestar first... a great experience.
