"Great. The contractor from Jimmy Gusky arrived on time and within 45 minutes had provided a full inspection and determined the unit was fine and had simply malfunctioned temporarily during several extremely hot day.s. So this saved me many thousands of dollars. Great experience."

"I had to replace a water heater quickly. Gave me a competitive quote with a water heater with desirable specs within a day and scheduled me the day after. Technician was knowledgeable and efficiently performed the work. Water heater performs just fine. Cleaned up workspace and took a few mins to walk through water heater and maintenance after."

"Excellent company! My water heater stopped working on New Years Eve. Unfortunately, the water heater is behind my HVAC, so they had to remove the HVAC, remove the old water heater, install the new heater, and replace the HVAC. They did a perfect job. They also replaced the freon in my HVAC, because the prior repairmen didn’t add freon. In addition, they fixed the jets in my spa. The team arrived on time, displayed professionalism, and cleaned up afterwards. I would definitely hire them again."

"My well pump pressure tank needed service and I called Friday and Barbara was very professional and eager to help. She took the time to understand the issue and even reviewed the pictures. Barbara is very passionate about her job. She was able to schedule for Saturday. Dave came out. He called to let me know that he was on his way and let me know when he will arrive. He was very punctual, professional, friendly, and down to business. Totally impressed with the way he solved the problem and made sure that answered all of my questions. This company is very ethical and I would recommend them to anyone."

"Our service technician was David. He arrived earlier than expected and went straight to work. Our new pump was installed in less than one hour. We were pleased with the work. He came after hours 6:30pm and did not charge an exorbitant fee. He was pleasant and very informative when asked questions. If there was a topic he was not familiar with he answer "I'm not sure". I like reliable companies with professional employees. We had another plumber come earlier and wanted to charge us $452 dollars for a 1/2 HP pump that cost on average $242, $200 for accessories for installation (I paid $276 taxes included for pump and accessories), labor charge to go and pick up the pump and to install the pump. His price $1252. I was told that it was considered an emergency so that is why the price was so high. This was the morning two days after the flood. After we got the pump we called several times and no response as of yet, He's off my list completely. I share this illustration so that buyers can make educated decisions about how best to spend their money. I don't assume that the plumber whose charges were 50% higher than anyone else I called on Angies List. I simply say do your homework and know what is considered a fair price. Thank you Jerry's Heating and Plumbing. You do excellent work in a timely fashion!"

"Not only were the leaks addressed, Drain Surgeon also wrote a memo to me as to what was found. The tenant had turned the hot water heater up to maximum. This resulted in deterioration of the washers and hoses causing the leaks. They even included a photo of the temperature mechanism set where it was when they arrived and as it was re-set once the repairs were done. I used their memo to discuss sharing the cost of the repairs with the tenant. I also use this same company for work at my own home. I am a very happy customer on both fronts. Thank you."

"Put in the call on a Saturday, since heater needed replacement on a Monday.  The serviceman was excellent and very professional, really exemplary representing his company. He thoroughly explained not only the problem of the breakdown, but each stage of the needed repair (with brilliant clarity), future do's and don't's and maintenance needs. I was anticipating an expense repair (heater was free since it was under waranty).  It was approximately $500 more than I expected due to an expensive part (backflow preventer). I'm still in sticker schock from that item.  This expense and the fact that there is no official discount from the pre-repair/emergency response visit are the only "negatives."  The actual service charges were reasonable, and at least, at market rate.  If you are in a situation where you can have your service within business hours during the week, do that you save yourself the emergency service charge of $134. Overall:  Magnolia is well-established and offers reliable service (for instance, they do several follow up calls at different stages of the repair).
