When my AC was running but not cooling my house, I panicked as it was a Saturday and I worried…read moreabout being able to sleep in such a warm house. I reached out to HALO on Yelp and within an hour they let me know someone could be here in the afternoon. Chernet came out and diagnosed the issue quickly, replaced the capacitor in 5 minutes, and made double sure the air was cooling as it should. The price was very reasonable (especially for a Saturday) and the service was fast, friendly, and honest. I'll definitely keep HALO in mind for future needs!

I am so glad I found Halo HVAC through Yelp! My AC stopped cooling in a heat wave and I had many…read moreother companies quoting me $200++ for diagnostics or unable/unwilling to come out for weeks. I went to Yelp looking for a better option and definitely found one! Halo was able to come out within a couple days of contacting them and the diagnostic fee was $89, which was to be applied to any work performed if needed. it turned out it was a tripped breaker they were able to reset and my system is cooling perfectly again... for $89!! The most notable and appreciated factor for me is they didn't come in trying to sell me service plans, upgrades to my system or accessories, or otherwise upsell me on a well maintained and well functioning older HVAC system. Even when I asked for a quote on a heat pump to take advantage of the rebates while they last, Halo didn't push me to pick the most expensive option or upsell me on a pricier type of system. And icing on the cake - despite a lot of in and out while working on figuring things out, my technician was constantly putting on and taking off booties to keep my house clean. It's a small token of respect that goes a long way, and I very much appreciate it! I'll be using Halo and referring them to friends and family in the future!

I like that they track and document every service provided with photographs and that if they can send the same technician each time, they do so that person has a good memory of your situation with your home. They have always been prompt at returning calls and helping me figure out what I need. Even if their prices might be a wee bit high here and there, the peace of mind to know that we are being taken care of is worth it to me. I like knowing they have our house history, they have established a relationship with me over the years and I know that when they offer me options its not to just get all they can - there is a purposeful reason. If you are in a situation where you need an airtight service with a tracked repair history that you can look up in images etc, then this is a great place to call for assistance.

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.

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 am sure the other bigger heating company would have charged twice the price and probably would have convinced me I needed a new furnace.

CMS is now owned by Welzig. I really liked CMS for general service because they never tried to sell…read moreme anything, they just came and serviced what I have and kept it running in top shape. I hired Welzig once, and a CMS technician showed up to do the service. He did the work quickly and replaced my humidifier contactor pad for free, but then the selling started. Replace my perfectly good Honeywell thermostat with a smart controller ($500+) that uses forecasts from the internet instead of the house temperature to decide when to run. Clean the ducts for $1,000 (do they know about the ValPak $299 company?). Add a water alarm device for $500 (I already have one from a multipack I got at Costco for $20). Literally $10k in recommended "improvements", and they really really wanted me to sign up for a service membership. Sure I get my tune ups, but also a plumbing and electrical consult I don't need each year. I have no confidence whatsoever they wouldn't intentionally damage or fail to service my unit in order to get me to buy a new one. I'm a redneck engineer from the South. I'm used to chainsawing my way out of the neighborhood after hurricanes, building blast furnaces using old lawnmowers, and cobbling together whatever I'm wanting to make (chicken coops, rabbit hutches, fences, you name it) out of whatever scraps are laying around or free on Craigslist. I'm scrappier and more miserly than most, but for those like me who are inclined to open their condenser when it stops running instead of calling an HVAC company to spend $250 on diagnostics, this is not the company for you anymore.

Austin was dispatched to my house from a warranty company. After doing a incomplete diagnosis, he…read moremade the incorrect determination that the condenser coils were dirty and that caused the compressor to burn out. He didn't look at the evaporator coils inside or even put gauges on the system to see how much refrigerant was left. Had he done that, he would have seen the oil stained hole in the evaporator coil and there was very little refrigerant left in the system. The low pressure was the reason the compressor wouldn't kick on, it wasn't even burned out. Due to his incorrect diagnosis, the warranty company denied my claim. He actually called me a retard!
