GTK Hvac

I highly recommend them for any work you want to have done.

On December 29, 2015, I decided to finally get my heater checked out (no heat), so I called GTK and made 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 2^nd) from Noël, 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!

Wow! First time that I ever had an honest AC person. I had some issues with my AC at my house. The service person honest and did not try to sell me anything I did not need. I had another AC company give me a price that was double what they told me.
Being in real estate no questions I would only recommend this AC Company to everybody. They fixed the problem and they have excellent service people. GTK should your first choice when it comes to fixing or for your service anything to do with AC issues. I would give them 10 stars if I could. The big plus they keep their word when it comes to timing.
Honesty 10+
Customer Service 10+
Schedule 10+

Tom really came through for me again, and was able to fix a part on my AC/​furnace without having to pay for an entire assembly!!! He showed up on a weekend within 3 hours of my call, and as always, he is super honest, and knows his stuff.

GTK is a company that you can trust and I highly recommend them for any HVAC needs. I discovered them through our building management and am happy to say the level of service they provide is great. It’s easy to book an appointment and they are fast, efficient and know their stuff.

Noël & Tom have been servicing our AC/​Heating systems for about 13 years now (before Unilocal even existed!). They are dependable and honest. I have never felt I can trust a service company more than I can GTK. My AC unit is over 20 years old and still going strong thanks to them. I know they’ve saved us lots of money over the years and will be my first call every time. Thanks Noël & Tom!

GTK is by far the best. We had 2 other companies try and sell us a new unit but Tom repaired our existing unit and after almost one year it’s still working perfect. Thanks Tom for saving us lots of money.

With the glut of L.A. contractors in L.A., you’d think more of them would be competent. I called 6 places today and left messages, yet no one called me back.
I called GTK and got a call back within an hour.
We’ve only ever dealt with Tom, who knows what he’s doing, is easy going, easy to get ahold of and gets the work done without a hassle.

We just had Noël from GTK come over to give us an estimate of what it would cost to fix our air/​heating. We expected this to be a big project that could run into the thousands. Noël came in and gave us the good news that he could fix our problem for under $ 200.00. I can’t believe we waited so long to call. Next time we will call GTK right away! If you are looking for fair, friendly and honest service, GTK is the place to call!

I’ve been working with Tom from GTK for a few years now, he has been taking care of the apartment building I manage for many years. He does great work, shows up on time and does not overcharge. He always tries to repair before he recommends any replacements. You can always trust him!

Thank you Thomas and Noël for your honesty and great service! Once again you saved me in a time of need. You repaired my heater in Dec. 2011 for just your service call.
I remembered your name from the last time, three years ago, when you repaired my Air Conditioner on the roof for a very fair price. With this job you told me that someone had intentionally loosened the bolts for the Freon.
To all: THESE GUYS DO A GREAT JOB AND YOU CAN TRUST THEM.
