The technician was very courteous, explained the process and stuck around after the installation to make sure everything was running properly and to answer any questions that I might have. I also received pricing from the big box retailers. B's custom Mechanical was a lower price without the hassle of dealing with middle men.

All I had to say is that mother had COPD and no air and all of a sudden he was in motion. He arrived within the hour and began to work on the air. He fixed the air conditioning and made sure the house was cooling. He told me that all was fine. Dave became my mother's hero that day and also mine as his charge was reasonable and extremely fare. There is absolutely NO ONE ELSE I WILL EVER CALL.

He also uninstalled a few Navien on-demand hot water heaters. He brings a modest set-up with no wasted capital. Other heating and cooling companies install crap self-branded and logo'd ductwork.

The installation was efficient, he was extremely thorough, and we were very satisfied with the entire experience. Fast forward another 6 months or so and we ran into issues with our AC. Of course during a heat wave... and Adam was again meticulous and professional. Even with hvac issues unrelated to his installations he responds to questions and is always helpful. We can tell he considers the long-term rather than the quick buck. Overall the best contractor / service pro we have dealt with, period.

I don't understand these positive reviews. I paid this company $100 to do an inspection. The kid…read more(and I do mean kid) that came out was able to show me on his tablet that the refrigerant in my central A/C unit is slightly below what would be considered a "good" level. I explained to him that my unit occasionally turns off and then back on in very short intervals. He wasn't able to offer any thoughts as to why that might be happening other than my unit is old. Fast forward 2 weeks. Today, I had a different company come out. Within 30 seconds of him taking off the same exact shield on the back of my A/C unit, he saw a frayed wire. Within 5 minutes he had replaced the wire and the problem was solved. One would think that the kid from Comfort Zone would have noticed it. The guy who was here today showed me the wire, it was RIGHT in front of exactly where the Comfort Zone kid hooked up the same diagnostic tools. If I'm paying to have my unit inspected, I'd think a company is actually INSPECTING the unit. I'm tempted to report this to the BBB. What a complete and utter rip off!!!
