And since I'm in a condo there were some limitations. But Brian also does the CONSTRUCTION necessary to address any unexpected situation. A Board Member told me Nordstrom was already installing a 2nd A/C unit in the exterior wall of the unit next to mine. I called Brian. He not only found a perfect unit that fit the ANCIENT constraints of the existing sleeve the building had, but the price was great, it has a remote, a HEATER! Did I say it's also really great looking. And even though (after removing my old unit) the interior of the sleeve had some unexpected tricks up its sleeve, he worked around them ingeniously, carefully and in an aesthetically pleasing way! HIS PRICING WAS GREAT. AND it was effortless for me AND...he made sure I knew that if I had any questions in the coming weeks of using it i should get in touch. He worked CLEAN and FAST. (I had dreaded the day the A/C would finally die and I'd need to go through major machinations. But THIS was a DREAM!)

I have had some pretty bad service issues that he always has always taken care of efficiently.

Last year I had to replace my ancient (1930s) heater for my duplex and his price was way below other bids. Not sure how any one could give him anything less than 5 stars. I highly recommend JD Comfort for any HVAC needs.

I originally called the previous company he worked for (starts with M like a famous inland sea or a diet) and their soonest appointment was 3 weeks out.

I told him I want to keep my 20 year old ac in good running condition and don't want any pressure to buy a new unit. Unlike the prior technician from M company who couldn't talk enough crap about my "old" ac. So I highly recommend Nshan. He started his own company and provides responsive, high quality service!

Unfortunately, my experience ended up not being as good as what I'm reading here! We had engaged…read morethe company once before at our previous residence and everything went well and then we engaged them to update our systems in our new residence some 15 years later. In between, we had also made referrals to the company. We had the electricity outage recently as a result of high winds in the LA metro area, which was national news. After the electricity came back, we noticed that our heating system was blowing cold air. Mind you that we've only had the system for 2 months here at the new residence. I called the company and Kenny came by and put the system back on. I asked if this was going to occur every time there was a power outage, and the response was "no it's an isolated case", and yet we were billed $165 to have our system going again. Really??? I called and stated that we've never had this issue before at our previous residences due to a power outage, and just went in circles with him. I paid his bill but mentioned that we would not engage him anymore if needed and got no response obviously indicating that he could care less!! This is not a service that someone needs frequently, but if needed again, we will certainly not engage them. Too much arrogance for my tolerance level and clearly he's lost sight of the fact that his clients are the ones having made his business successful. More disturbing is that he had been highly recommended to us.

On December 29, 2015, I decided to finally get my heater checked out (no heat), so I called GTK and…read moremade an appointment with Tom. He came over that evening and started to check out my thermostat and internal HVAC components. After a few minutes, we decided to take to the roof for a closer look at the actual unit. While on the roof, he explained that I had a leak and about half my freon was gone (my HVAC requires freon for both the cooling and heating). I told Tom to go ahead and give it more freon with a sealant that he recommended (he did advise me that any gas job would not be guaranteed, but that he had good success with the sealant - about 90% success rate). The job would cost me $450. He pumped in freon and gave it some sealant and it seemed to work that night. I was told to keep it running for at least two hours. The very next day (less than 24 hours later) the heater was no longer working. I tried again the day after that. No luck. When I called Tom, he said that he would send someone over as soon as he had the chance. I got a call today (January 2nd) from Noel, but I said not to come. I wasn't prepared to have them come back or pay more after what I found out today. I had someone else take a look at my HVAC today and he advised me that GTK made some very serious mistakes. While I was supposed to have approximately 70 PSI of pressure on the low range, I had almost double at 135 PSI. The pressure and amount of freon that was given was so high it was causing all kinds of problems (over heating, auto shut off, down compressor, etc.). Just having more freon is not a good thing. There needs to be a good balance of freon and pressure to ensure the unit works properly. After spending the day reversing $450 worth of freon out of my HVAC, it is finally working properly. Although I wasted $450 (which by the way is also very expensive... I was told I should've been charged closer to $300), it was a lesson I had to learn the hard way. Take a close look at the reviews for GTK and decipher which ones are fabricated or real. Good luck!
