Eric serviced our air conditioner; outstanding. Our system is significantly more efficient now that it's clean. Tristan was amazing. He advised me to close vents/redirect air to the rooms that needed more heat and to leave on the fan to protect our HVAC system: : : he did suggest adding a line to the basement to give more heat as well which we will likely do. He was an extremely knowledgeable, skilled and kind service man : thank you-Julianne

The technician was polite and friendly. He explained the process and results. Would recommend to my friends.


“Called at 7:30 am On a Sunday. I noticed A/C wasn’t working later the day before. Tech told me how to enter trouble code area on my thermostat. Read the codes to him. He came over on a Sunday and found the starting capacitor failed. Replaced it and system is running again. 11 year old Carrier A/C unit.”

“Chris came to our home on time to fix our air conditioner. Interstate called me early in the morning. Interstate was returning my phone call (I had left a message), to schedule a technician to come to my house. Chris showed up at my house on time 4 hrs later to investigate the air conditioner problem. It took him approximately 30 minutes to diagnose and fix the problem. There was a broken piece of equipment called a capacitor. The bottom line is the problem is fixed and cool air was wafting inside my house in approximately 30 minutes. I certainly could not have asked for better service!”
