For 2 years they came and said my refrigerant was low on my 3 year old unit and charged me for it .. turns out they just didn't want to have to come out of pocket for labor on their warranty, there is a leak on the evaporator coil .. this is my second bad experience after they told me I needed a new Furance rather then using the warranty on the Furance to replace .. run from them !

Don't hire this company,you will regret letter on.In January this year,they installed furnace and ac in my house.They didn't get permit for job.They try install cheaper unit(furnace),when I found it,they sent new unit and install.They didn't properly install exhaust pipe from furnace to r roof.I was exposed to carbon monoxide leaking for a couple of weeks. When I found it, i call king heating and cooling and they sent gay Who properly install exhaust pipe. In March they sent guy to charge AC with Freon . After couple weeks I when I turn on AC I found that AC doesn't work. When I call king heating and cooling, Manager refuse to send technician. I called different heating and cooling company and they found that ac wasn't it properly charge with freon. They charge me for freon(two pounds) and service $145. Only response from King is that they try delete my post. Avoid them at .

Our air conditioner went out early Friday evening. I called to get on the list for Saturday.I was offered emergency service and declined. I received a call within a half hour assuring they could come Saturday and i would receive a call in the morning to schedule.
Even better Saturday morning I received a call from Chris saying he would be here in 20 minutes. Chris was professional and courteous and diagnosed the trouble in a few minutes. After he got the air conditioner running, he found the freon low and replaced that also.
He offered a discount if we signed up for their yearly maintenance plan for $148, which seamed reasonable for yearly air and furnace checkups and discounted repairs. We don't usually take these type of plans but since both units are 11 years old and I was pleased with the service we signed up.

We had a leak that we figured out was due to our AC. We called and within a day had someone out for a diagnostic, in another day an estimate and service and installation a day later. I can't say enough about the great customer service we received it helped make a stressful situation much much easier. Very professional and I would highly recommend them.

They came thru again. My rooftop at my office broke and in less than 24 hours they had my new unit installed. This was great because the unit is big and they had to get a crane out to get the job done. It also happened to be the coldest day of the year. With this outstanding service I had no business interruption. Excellent Peace of Mind!

Thank you!

We've worked with King twice in two different homes. Each time we have received fantastic, knowledgeable and trustworthy service. Giuseppe is very thorough and straightforward. He explained what was happening with our heating and cooling and did not try to sell us anything but objectively laid out our options. When we decided to replace our furnace and air conditioner we felt we were given a very fair price and the installers, Steve and Phil, did a very, very professional job. We highly recommend them - great job!

I have to say it was a pleasure working with King. They were very professional and helpful. Brandon T. was extremely helpful and great to work with. I would highly recommend them and will definitely use them in the future.

They wanted $90 just to quote me how much it would cost to install four toilets. There was no issue to diagnose. I just wanted to replace all my toilets because I just bought the house.
So they could show up, quote $1000 per toilet, then when I decline the quote they walk away with my $90. These guys are hustling people with a policy like this.

Reviews give the consumer power and protection from businesses like this who are on the take.
