"Val came on a Saturday evening within two hours and replaced my thermostat! His fee was far less than anyone else, and others couldn’t make it until days later. The temps are in the 90’s and I need my AC! I am so pleased at the quality of his work and his friendly professional demeanor!"

"The service tech(Chris) was very courteous and knowledgeable. I told him before he came that the fan was running intermittently. He said he would be out in the morning with the motor in case that was the problem. Turns out the fan was fine and it was a solenoid that was bad. He could have replaced the fan and the solenoid and made more money for himself and the company. He just replaced the bad solenoid. He fixed my AC in less than half a day during a heat wave and saved me money! If anybody asked if I know good and honest HVAC place I will recommend "Generations"."

"Elvis did a great job today fixing our HVAC and surprisingly charged a very fair and very reasonable professional fee. I definitely will recommend him to family, friends, neighbors. You should try him first before calling other companies. You would be very pleased if you did that. He came on time. He was very professional 100%. I lined up annual project for him to tune up and inspect our HVAC to keep it good running condition."

"The service guy came out very quickly. Had a smart thermostat installed. He walked me through setting up the app. Did a fast and a great job. I highly recommend this company if you want it done and done right."

"The old air conditioner was installed after purchasing new windows. The window company installed it as though it would never be removed. The prior handyman could not remove it after 3 hours of trying. Ivan and his worker removed it in 30 minutes. The entire job was completed in less than 90 minutes."

"Got quotes from several companies and they were far and away the lowest price, next closest was almost $2k more. Guys came in and installed dual furnace and free humidifier in a day. Highly recommend."

"Raylor and Jeffrey replaced 3 fence posts and then painted our 100’ Cedar fence. They were extremely careful that paint did not get on our patio and sidewalk and also in our neighbor’s yard. They did a wonderful job. I highly recommend them."
