Therma Tech installation team leader and members completed the job right on schedule. They were on time, courteous, patient in answering our questions, and kept the work area clean.

My HVAC system stopped working properly…read moreafter another company had spent about two hours diagnosing it and quoted me more than $3,000 for a new control board, contactor, transformer, surge protector, and maintenance plan. Henry arrived, clearly explained each step of his diagnostic process, and quickly identified that the transformer and contactor were the actual issues. He completed the repair in about an hour and charged me $540 total, saving me roughly $2,500 compared with the previous quote. What impressed me most was Henry's honesty, expertise, and transparency. He did not try to upsell me or replace parts that were not needed. He took the time to explain what had failed, why the system was not powering on, and what he was doing to fix it. It is rare to find an HVAC company that combines strong technical knowledge with fair pricing and integrity. I would absolutely recommend ThermaTech to anyone looking for an honest and skilled HVAC professional.

He was very friendly on the phone and asked me key questions to help diagnose my issue. Since he was in the area, it only took him 10 mins to arrive.

Sal was very friendly and professional the whole time and his price was very competitive! He also gave me helpful tips to prolong the life of my unit. Fantastic work by Sal! From opening up the Yelp project to CostLess fixing my A/C....less than 1 hour! Simply amazing! I strongly recommend CostLess for any of your HVAC needs!

Fuse came in significantly lower priced than everyone for a superior system. We wanted to add an additional vent on the main floor, and some dampers for a few of the vents and everything went like butter. Lex and Maxat were the nicest people, arrived on time, left at 6pm each day leaving the house clean. It was a 3 day install and they finished on the third day. Beyond what they needed to do, Lex walked through things that would be checked by the inspectors even on work they didn't do (GFCI plugs close to where the old unit was), and walked me through why they did some of the things they did because I was curious. We're 3 days in so far, but the installation experience was great, and the daikin system is cooling the house great (and I can already see from the energy monitoring systems we have, it's so much more efficient!).

Teodor, our project manager, did a great job assessing our home and specifying the system. The installation crew, Azamat and Val, did excellent, careful work removing the old system, running new ductwork, and installing all the new equipment. The install took about 7 days.

Dennis Sushko and Slava (Comfort Advisor) came to my house to walk the site, review the scope of work, and thoroughly address all of my concerns. Jessica in the permit department was fantastic with scheduling--she was incredibly proactive, kept me updated every step of the way, and even helped fill out the paperwork for local rebates. On installation day, Tony and Adam showed up right on time. Both were extremely professional. Because of tight space constraints on my wall, they had to work extra hours to complete the installation in a single day so I wouldn't be left without power overnight. They also did a spotless job cleaning up the workspace before leaving. I strongly recommend Freon Service to anyone looking for HVAC work or an electrical panel upgrade!

His charges have been very reasonable. He doesn't do any upselling (like adding unneeded services).

My issue was needing the capacitor replaced. The fix was quick and I was clearly over charged. When I asked about this, the technician just said it's just business. He exaggerated the price of the part needed which is a capacitor saying it's like $200-$300. It's at most $50. It took him like 10 minutes to replace the part and said you either accept the charge and pay or I just take it out. It felt very predatory, like I already fixed it you might as well pay. He proceeds to measure temps and other various things just to pass time while he waits for me to decide if I want to pay or have him unfix it. I can accept being over charged but something about how this situation transpired left a bad taste for me. For example, why wouldn't you say you need to replace this and it cost this much for the fix instead of fixing it first then say pay or I take it off.

The quoting process was straightforward -- no pressure, no mystery line items, and they actually explained the equipment options instead of just pushing the most expensive thing. Install crew was on time, respectful of the house, and left the place clean. Where they really stood out was everything after the install. Anyone who's done a permitted HVAC job knows the paperwork is where contractors go quiet. Not here. HERS testing forms, city inspection scheduling, warranty registration, and the maintenance plan were all sorted out. Hyman, Jean, and Khaled were each responsive whenever I needed something. No chasing, no dead ends. The system has been running well and the house is noticeably more comfortable. Easy recommendation.

The install has been fantastic quality and the crew listened to everything I wanted every step of the way. They mounted rat spikes where I wanted, they put the lines and the units exactly where I asked and I've had no issues at all.

I scheduled an appointment for them to come check out my house, and Rudy showed up right on time. They even sent me a text with live tracking on the day of the appointment, which was a nice touch. Rudy was really nice and patient. He explained the different systems and gave me a couple of options without trying to push me into anything. I'm still not sure which system is best for my house, so I haven't made a decision yet. My current HVAC is almost three decades old, but I'm not in a hurry to replace it. Their quotes are competitive, and so far, I'm really impressed with the service. As they say, first impressions matter, and IRBIS definitely made a good one.
