I just googled about it and i found his contact number , and i got my problem solved , because i called him and he actually explained everything very clearly and amazingly! Thank you so much
My tankless water heater was showing E110 , i was unable to get that, but he told me that you need clean the air intake filter then i open the panel and did exactly what he told me to do. By that why i got my problem solved!
Thanks buddy
Technician was very professional, found that I had an igniter problem, had a spare part with him and solved the problem within an hour.
Reasonable pricing and very professional. Highly recommended!!!
I called him for advice when another well known Hvac company wrongly diagnosed my Trane furnace blower noise and told me I needed to undergo a $1500 repair. Yuri quickly assessed the problem and voila no more blower motor problems. All for $140!!
Thank you Yuri! I highly recommend your service, honesty and expertise.
