“We had a pipe leak in our eaves and called multiple companies last night.”
We had a pipe leak in our eaves and called multiple companies last night. King got to us the soonest even if it couldn't be overnight they beat another company that said they would be out before them this morning. Then once the tech came he was super efficient and got our issue resolved in less than an hour. He even recommended us a restoration company to take a look at the water damage. Amazing work! Thank you!

“My tech Jerry is examplary.”
My tech Jerry is examplary. He explains what he is doing in a way that is understandable. He advised and recommended without pressure. He is knowledgeable and experienced. This is the second time I have had the pleasure of Jerry servicing my furnace. In each case he was able to diagnose and repair the problem. I would recommend King Heating and especially Jerry

“Great first experience today.”
Great first experience today. Within 30 mins Santiago had improved the efficiency and output of our furnace. He was prompt and pleasant (our dog liked him, too! ), explained everything with detail and stuck around to make sure the second phase of heat was also in order. Would recommend.

“Jerry was very efficient and thorough.”
Jerry was very efficient and thorough. He explained everything he did, and he was careful to explain what needed to be addressed in the future. He documented the work he did as well as took pictures. He was not pushy and he was respectful of our association's finantial limitations. He applied coupons available to us. He even took the time to wash the boiler room floor before he left.

Jerry was great! He wasn’t pushy and was honest. He tightened some radiator valves instead of replacing them like I thought they he to be. He also serviced our boiler and didn’t try to push us for a new one when we didn’t need one. Would highly recommend these guys!
