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)

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.

Tech was great, answered all my questions and even came back a week later to check my AC Freon levels.

I would recommend them highly and you will not get ripped off. Very good experience and great company.

We had an issue with our A/C unit turning off and on. We called another company initially to come…read moreout and diagnose the problem, but they were totally confounded and had zero ideas. Did a little research and found Impact online and called for help as they are a certified Carrier dealer and service provider with great reviews. I first interacted Sarah and Jessica at the office and they were wonderful. They helped me get an appointment ASAP which is never easy in the summer months, and scheduled us with Danny, our current and forever service technician. Danny is super knowledgeable and treated both my wife and I respectfully and honesty. Carrier itself had no idea how to fix it when he called them, so Danny dug his heels in, did some research and figured it out, talking us through each step of his diagnostic process and making his best recommendation on how to fix our air conditioner. Sarah and Jessica also stayed in touch with us every step of the way regarding scheduling. They called me before I had to call them about a part that was taking a little longer than expected and kept me up to date. Their customer service was absolutely gold standard. Together, they all fixed a problem that it didn't seem like anyone else could. All for a price that made me smile as much as any one person can before parting with money. All this to say, call them. They're the best.

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.

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.

We had a water leak in my twelve year old 96% efficient Amana furnace and I placed a call to Davey. Dorothy was very courteous sent out her son Junior to look at what was going on. He told me he was going to condemn my furnace though there was no signs of aerial contamination. I told him I'll go out and buy two expensive meters and they both showed ZERO contamination! Ok, Junior then said the furnace would be covered under replacement warranty as the heat exchanger was cracked. He talked to the local dispatcher and they had a unit in stock. I was then told by Junior that it would cost me THIRTY FIVE HUNDRED to get the job done. I was flabbergasted at the price! This was for labor! Unbelievable! Ok it was winter and cold temps needed to be handled so I told him let's do it. Junior returned and started installing all the while informing me that it would cost me another EIGHT HUNDRED! I told him no way! Mind you, my old unit was removed and brought downtown. He called his office and they backed off on the additional eight hundred. I left Junior alone and he put together the new furnace and installed it! It was not straight, not plumbed and he left after the furnace was running. I called Dorothy and COMPLAINED! She sent Senior out and he straightened things out. The inspector came by and failed the inspection. Senior came out again and touched up all the work. Senior had to come by a third time to rewire the condensate pump... to code! That final time he came, I could tell he was PO'ed at returning and never said a darn word to me. No respect at all! Bottom line, I was ripped off to high heaven. Thirty five hundred... for the work done? Maybe they get this from other uneducated customers but the unit was under warranty, the whole installation with labor should have cost me $2000 at MOST! I found an unbelievably reputable HVAC and they have so far treated me with respect and professionalism especially when it comes to pricing and top notch customer service. Just had to share this with potential customers here in the area.
