"I purchased a deal with Liberty Plumbing, and within a day they had responded to offer me an appointment for one of the three dates I had requested.  I had a specific question about clearing my condensate line so I sent them a message and within the hour I received a response.  Very impressive!  The technician, Terry, called me at the start of the scheduled window of time to say he was on his way.  When he arrived he was very pleasant and professional, and listened to my concerns regarding an apparent clog in the condensate line. I've had two prior leaks in the past 18 months going not only into the wall from the floor in the attic, but travelling another floor below into the ceiling of my garage beneath my condo's living space.  Obviously the line had not been thoroughly cleared at my service call the year before before (by another company) and so that problem was never resolved. I can say that confidently because I use my a/c only when the temp rises above 92 for more than one day since my home stays fairly cool.  But we had relentless heat waves last summer and as a result of the unit routinely running for a few days I had another leak and had to discontinue using a/c until everything could dry out, which was really uncomfortable. Terry thoroughly cleaned my compressor outside and cleared the condensate line, and to ease my fears, he confirmed it by pouring water into the overflow line so I could listen to the water travel to the pipes under the bathroom sink.  Thank you, Liberty Plumbing!  I feel confident this has resolved the leak issue, and now I can stay on top of keeping the line clear. Excellent work, no additional fee's, and I will definitely use them in the future to keep everything in order.

"This was the first time I requested HAVC service from Magnolia Heating and Cooling. I definitely will contact them again. The employees Kirk and John arrived on time. They listened to my concerns, explained what they were going to do, and they were respectful, and integral. Based on my experience, I believe Magnolia Heating and Cooling is a reliable company. D.A."

"Albert was very polite, helpful and showed me some easier ways to maintain my system. He also offered suggestions on how to best utilize the 2 systems we have to best advantage. I was notified when he would arrive (along with a photo), then an update (as he was early), and work was completed in a timely, efficient manner. I would definitely use Southland Heating again!"

"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

"I can't edit previous review so posting new one: I am revising my previous review. After posting my first review, Danny in Customer Service at Home Comfort USA contacted me. Danny very patiently listened to my situation and frustration and told me he would look into it, but wouldn’t “leave me hanging” and would call back. He did call back and fast-tracked a HVAC technician, Jad, to come out, who was great and called in a higher-level technician two days later. Then the higher-level technician came out a couple of days after that and found we did need a leaking core replaced and said Danny would call me. Danny did call me and went above and beyond to get the part replaced under the manufacturer’s warranty. Two days after that, Home Comfort USA came out, replaced the core, tested our HVAC, and mitigated the labor. We are now VERY happy customers with Home Comfort USA and very grateful for Danny’s great customer service and intervention. I am writing this review on a day in the mid-90s with our HVAC system keeping us VERY comfortable. Thank you."
