I tried out 3 different HVAC contractors, multiple times before finding Koldair. I gave them a try because a friend from my car club worked for them, and I had major complaints with every other HVAC contractor I dealt with.
Bob has been very accommodating since day one, always sending someone to take care of our issues within a day, sometimes even same day. That's why now Koldair is handling 2 dozen buildings for me.
The first year, Bob recommended we perform spring/fall tune-ups so all our units get inspected just prior to cooling/heating season. Since many of our units are around 30 years old. That first year we probably ended up spending around $30k on repairs and replacements. In the two following years, our rates of failures and issues on our HVAC units dropped significantly, I'd estimate we were calling in issues 1/4-1/3 as much as we did before switching to Koldair.
Highly recommended!
