Beware. I contacted this company when I couldn't reach my regular company. The company sent out a tech to my rental property and they said that my system wouldn't hold pressure and I needed a whole new A/C system for a charge of about $5500. I then called another company who tested the system and just said that it needed cleaned and recharged. They only charged me $150.
6 months later and still no issues. $150 vs. $5500 - you decide!
