Charged me $89 dollars to come out when they got there all he did was look at the furnace say it had water damage then said I would need a new furnace. Meanwhile leaving my family in the cold without even trying to fix it. Called another company they changed out the inducer motor and the furnace is back up and working. Stay away from this company.

We had an emergency plumbing situation that required much more work than anticipated. Able worked so hard and so long to fix the twisted plumbing and didn't give up until he solved the problem. Give this man a raise!!

They were happy to take our $148 to have summer and winter clean and check. When they came out to clean our AC unit they wouldn't clean the Acoil (evaporator coil). They explained that they can never get dirty. Funny the air comes in past the filter and through the A-Coil, this happens year round. Then they wanted to charge me an additional $125 to clean the A-coil.

Yeah, if you want half the job done for full price call King Heating and Cooling.

My a/c broke down during the day on the 4th of July, and I didn't know about it until I went to sleep that night and it was 85 degrees and baking in my bedroom. The next morning I called King to come out and fix it, and I was told I needed to buy a new furnace. I said I only wanted someone to come out and fix it, and I was told there would be a $89 charge for someone to come out, but a visit would be free if I bought a new furnace. I said I wanted the repair, and again I was told about the $89 fee. It was mentioned a third time before I got off the phone, so I knew for sure I was getting charged $89.

When Joe came out, I explained the outside a/c unit was running but not the furnace, that I had tried changing the thermostat and checked the circuit breaker. He did NOT put on any shoe covers (I have white carpeting upstairs) and we went into the attic. He took the covers off the furnace, and he said that he could tell by the humming sound that the electric motor was seized and would need to be replaced. He also said he could ""sense"" that the system was out of freon, just from experience. He left the furnace taken apart. We went down stairs and he started to write up the repair bill. He said I needed the new motor, and would also need a new furnace fan and a capacitor, for a whopping total of $1725. Oh and that because of the 4th of July he couldn't get the parts until the middle of the next week. He also said that he was ""obligated"" to provide me with a quote on buying a brand new furnace, which he could have installed the next day or two. That quote came in at over $3600. And since Joe was looking out for me, he said he would give me the senior citizen discount, even though I am not, along with the military discount, even though I am not a veteran, and would even throw in a new thermostat for free. I was in a state of shock, and he left and said I should get back to him.

Out of sheer desperation I called another company, just to see if maybe they might have the parts. They came out, and explained that my motor was NOT seized at all, I did NOT need a new furnace fan, and the only thing it needed was a new capacitor, which he showed me was bulging and visibly deformed (the new capacitor replacement cost me a total of $260). Funny how Joe missed that obvious and very visible clue as to what was wrong. And even more funny how he was trying to railroad me into buying a new furnace, or pay for totally unneeded repairs and parts. So basically I was totally lied to about what was wrong and what was needed. Joe was a good trooper and did send me the quote via email, and also sent a follow up email asking if I was ready to give him some business. I wouldn't give Joe or King a penny if they were the last company in business. They are underhanded sleazy people to deal with, I would run away as fast as possible.

I called for routine maintenance on my tankless hot water heater because it was losing hot water. I was quoted $99 for coming out. The tech tells me the board is bad and wants $400 just for service. I will never call them again.

Wow, these guys are amazing. My blower motor went out and the forecast is calling for sub zero temperatures. I have an unusual model furnace and two others firms said they had to order it. Meaning I'd be without heat for three days. King had to order it too, but went out of their way to drive and pick it up. The owner came to my house and installed it same day! Unbelievable. Not only that they were cheaper! Great firm. Great people. Saved my rear end.

The sales pitch was good along with the the installation crew. I received a voicemail letting me know that my warranty will go into default status if I don't call and schedule an cleaning/inspection appointment. So I did that twice they give you a 4 hour window morning or afternoon. First time they were stuck at another job, second time I called they set up the wrong time. So I called upset about this and the office ladies did not help the situation out one bit. They caused me problems more than anything else.

Avoid this company at all cost. I called King out on the coldest night of year when my boiler would not ignite. I was desperate and they knew it. An inexperienced service man came out, did no real troubleshooting, just took some pictures, called into the office, and said my boiler was old and had a cracked heat exchanger (not true).

His invoice noted: Found relief valve not working clogged up fuel tank is full, reducing valve is clogged up with the water, central part have water damage, psi no, bake heat exchanger has slite crack, recommended to speak with advisor before doing repair.

He left with a final ""good luck"", without getting the boiler working, and charged $125 for the service call, without providing any service. He sent the pictures to someone else for guidance. Then, referred me to a salesman, for a new boiler quote.

Brandon quickly called me and said he reviewed the pictures and confirmed I had a cracked heat exchanger, the main block of the boiler. A 140K BTU Burnham boiler would cost $7687, or $6500 if I pay cash, but had to make the decision that night. Before spending that kind of money, I wanted a second opinion.

I called JSR. Joe came out and troubleshooted the problem using a meter, explained and followed the entire systems' operations, and got the boiler working within an hour. He charged me just $155, told me which part I needed to order to fix the immediate issue, and walked me through how to install it. I needed a new aquastat relay, since ours was not getting low voltage. The part was $200 vs $500 if he ordered and installed it. He agreed our 18 year old boiler was in rough shape, but with some maintenance, it could last us many more years.

I installed the new part but could not get the boiler to run again. JSR was not able to come by, but referred us to Van Drunen. They also reviewed the entire system. They determined that during the install, I may have accidentally tripped the rollout switch near the flue or it may have tripped due to the closed damper. He reset the switch and confirmed the damper is wide open and holds position.

He explained our DUNKIRK boiler could last up to 30 years if well maintained. While mine had not been, he still agreed it could last for years if I just serviced it and change out a few parts (reducing valve keeps filling and the pipe before is very corroded). He also agreed the heat exchanger is NOT cracked. He charged us just $145 ($78 for call and $70 for labor). Please, save yourself time, aggravation, & money and avoid this place and their unethical business practices.

We've been using King Heating/Cooling for a few years now. Not too often, but when something goes out or malfunctions we need someone who will answer the phone kindly, send someone quickly and have that person that does come be knowledgeable and honest. For us, this company has done all three.

Over the summer, Jonathon came out to do a minor repair. It was exactly how a call to an HVAC place should go. He was great to us. Good guy.

This week, on the coldest day of the year, our furnace went out and we called. This time, Vince came out to our house. He was a friendly, professional, family person and it was obvious that he had tons of experience both with HVAC and dealing with people. He gave us a very detailed explanation of what was wrong, how to maintain the furnace, what to look for in the future, what else was showing wear and gave us many, many options and ideas going forward.

We very much appreciated the high level of service that Vince performed and also the integrity that Vince showed. King Heating and Cooling is very lucky to have someone like Vince working for them.

Highly recommended for HVAC service.

I called king because I was having furnace issues I told them that I believed the gas control valve was sticking they had a tech at my house which was awesome and he did a fantastic job it was the gas control valve and he also found a cracked inducer motor he start to break down pricing for what was wrong and it totaled around $1500 I asked him what a new unit would cost and he told me that he didn't do the estimates for a new install but he would have someone that does that come out either the same day or they would contact me to setup an appointment well I waited for 4 hrs and no one showed or called I called another heating company they sent someone out estimated the job and installed the next morning I know king has been around for many years but it just seems foolish to let business go when all that was needed was a phone call and they would have had a loyal customer for life
