Had my first call with True Heating & Cooling today for basic maintenance. I was super pleased with…read morethe service and especially with the tech. 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)

I would highly recommend Efficient Comfort for any HVAC needs! My parents experienced a valve leak…read morefrom their humidifier that was connected to their AC and heating system at my childhood home, and the team was incredibly professional and quick to get the issue resolved. 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.

This is a great company to work with. Our boiler had gone out right after we receive our quote from…read moreJeremy for a new system. They were out in 2 days. Right before the 03/06/26 storm. Talk about just in the nick of time. Devon arrived first to start the removal of the old system, while hid partner Ruben went to pick up the new boiler. They worked solidly all day with nary a break. Clean, zero mess left behind. Small company (brother and sister run) with great prices. If needed, I will not hesitate to call them again.

Not only did 303 Heat came out on that same day they made sure I had space heaters to make it through the night. They went to Home Depot and bought space heaters for me to borrow and set them up for me at 7pm. The next day they replaced the furnace and the air conditioning and hauled everything away. They were friendly, personable, and professional. Highly recommend this company.

Very nice and prompt. AC needed a small part and it was replaced without the usual "trying to sell…read moreyou everything". Tech was great, answered all my questions and even came back a week later to check my AC Freon levels. He said they were all good, and again, could have sold me stuff I did not need, but was honest and would not even charge me for checking them. I would recommend them highly and you will not get ripped off. Very good experience and great company.

Within a few minutes of leaving a voicemail on Sunday, I received a text from Shannon not only scheduling our repair for first thing Monday but also offering to bring over space heaters to keep us warm until then. What a life saver! Dan and Charlie arrived at 8am. They diagnosed the problem, located the needed part, and completed the repair shortly thereafter for a fair and equitable price. Dan went above and beyond by addressing a couple of other issues and educating us in the process. Without a doubt this was the best HVAC service ever! Kudos to a true community family business that genuinely cares about the welfare of their customers.

After my AC unit went dead I began calling multiple venders. If they called back it was weeks -…read moreuntil I called Davey Heating and Air. Dorothy offered to schedule a tech that afternoon and then started running through the most common causes. With her on the line I found a blown fuse on the units motherboard and was able to replace it (props to Home Depot for having them in stock). Bottom line, she was polite, responsive AND helped me solve the issue over the phone at no cost. I will definitely call Davey Heating and Air for all my HVAC needs in the future.

Within ~10 minutes, got a call from this company who asked some basic questions and troubleshooted some things over the phone, without even talking amount payment or price. When that didn't work after an hour, I messaged back and they got me on the schedule for the next day (it was already 5pm by this time. They came promptly during the window and gave me heads up, figured out the issue in less than 15 minutes, and gave me a range of options and prices. He actually taught me several things about the AC and showed me how to do some repairs myself and where to get parts, and lo and behold it worked like a charm! Couldn't be happier with the quality, speed, and friendliness of the service. Got my AC pumping ice cold air in time to get the house cool for my kids' naps. Davey will absolutely be my go-to from now on and I would recommend them to anyone and everything.
