Exceptional & Thorough Tech Service
Mark Klotz, a seasoned technician, was the BEST tech I’ve ever had. He provided exceptional thorough service for a persistent HVAC system problem. He was COVID-19 cautious and compliant, professional, educational, polite, and FIXED a difficult problem that no one else caught. THANK YOU Air-Tech for sending him to my home. I have my A/C back!!

Outstanding work on the hottest day of the year
Mark arrived exactly at the appointment time and in the blazing heat analyzed and fixed our non-starting AC, then checked out the whole system, changed the filter and made several minor fixes. I was once again impressed by AIR-TECH and by Mark! A thousand thanks.

Great company. I called them for a maintenance and they sent a technician out the next morning. Mark arrived on time. Quickly took care of the needed maintenance for a fair price and made some recommendations for items to be done.

Highly recommend
I’ve used this company for 3 years (including semi-annual servicing) and will continue. The technician is on time, thorough, and polite (and he even puts on those paper shoe covers so he doesn’t track in dirt).

Steve - Arcadia, CA 91007
Excellent Service
Air tech came to my house to check my air conditioner. The technician (Mark) was on time, highly professional, and made 2 visits. Both visits were very professional, and he not only found my air conditioning problem, but he also found a gas leak in the attic and fixed it. He explained in detail what he was doing. I highly recommend this company.
Armik - Glendale, CA 91202
Informative Service Call for Vintage Floor heaters
I appreciated the information I received after Mark inspected the floor heaters at my property. I have had 2 other companies look at the units before and they never mentioned some important safety concerns that Mark brought to my attention.

Met Mark today and he readily understood the problem. He thoroughly inspected the system and found a leaky valve. Luckily, we are still under warranty for the parts and are scheduled to have it repaired by him next week. We are looking forward to having our ac system work again! Thanks Mark!

Justin - Rosemead, CA 91770
Top notch service
I've worked with a few a/c techs but none compare to Air Tech. They know their stuff and are very honest. I love the peace of mind that my a/c and heating equipment is being maintained 2x per year so I can be comfortable and avoid expensive repairs.
Jeff - Los Angeles, CA 90012
Immediate fix
Mark crawled over to our aging Lennox heater and initially proclaimed that there might be life with a new part. After some further diving into its innards he discovered a set screw that had loosened and proceeded to breathe life into the old guy. We should get a few more years out of it thanks to Mark’s knowledge and investigative skills.
Jack - Los Angeles, CA 90042
