"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done."

"Gave a bid at 8 AM and came back with a 40 Gal. water heater 2 hrs. later. Did the work and my renter had hot water in about 35 minutes. Good job. They have got my business. Thanks."

"The water line for my fridge cracked and it was raining in my basement. They were quick and responsive to coming out and performing the repair. They also said part of a nearby gas pipe was corroded as the leak had been ongoing and recommended replacing it as well. They came out the next morning and performed that repair. Cost was very reasonable for two site visits, labor and materials."

"My pro was Terell, and he was on time, friendly, and professional. He was very knowledgeable about my plumbing situation. After the problem was repaired, I liked how he kept asking if I had questions about any other issues in my house. Great worker!"
