Recommended Customer Reviews
Service technician told me my fan motor needed to be replaced. Quoted me a $1600 repair and approximately $4500 to replace with a new unit. Another company replaced my condenser for $100.
I asked to be refunded but I guess they would rather have my bad reviews instead of refunding me $100 for wasting my time. Which was 2 days of miserable heat.
LET THE BUYERS BEWARE
BECAUSE YOU CAN POSSIBLY GET RIPPED OFF AND NO ONE WILL CARE!!!!!
We have had both our furnace and air conditioner replaced by King. On both occasions the prices were fair and the work done perfectly. We highly recommend them.
Francis Y.Very expensive....Needed a shot of freon...Total bill $453.66...Tech was here less than half an hour...did nothing else.
Margaret B.Everything about dealing with King was happy. First, I called a few days ago, on Sunday, when my furnace quit. I was very happy to get an actual person, who asked a couple questions (along the lines of repair? replace?) and said someone would be out that day. ON A SUNDAY. Already, these guys have a customer for life. OK. Derek calls ahead, appears a bit later. He checks out the old furnace, we talk about options, cold spots, stuff like that. I chose a furnace, got a price, set installation (first available) for Tuesday - 2 days. The other places I talked to wouldn't even have a sales guy out until after that; good thing the outdoor temperature wasn't all that cold.
Installers came early Tuesday (yesterday), did a great job, showed me where to change the thing (forgot what it's called) in the humidifier and the filter in the furnace, even figured out how to get the Call for Service message off of my (not new) thermostat.
Very happy, and not freezing any more. Even the former cold spots in the house are nice and toasty.
Lauren R.I called King for our furnace tune up last year. No complaints, the tech was very nice and probably did a great job. I enrolled in the Royal treatment Plan at that time. According to their website, they were supposed to call me to schedule the A/C tuneup in the spring, but they never did. When furnace time came, I called and they said I could use the service credit for this year's furnace tuneup and start over in the spring. OK, fine. I scheduled our appointment and was given a 6 hour window. At the end of our 6 hour appointment window, no one had shown up. I called to ask if something happened and I needed to be rescheduled. I was told the tech was on the way. Another two hours and nothing- no one showed up, no call or text with an update or apologies and offer to reschedule. I called to tell them if someone was ""still coming"" I did not want anyone coming to the house this late. It's now 8pm and I have been waiting around for this appointment for 8 hours now. A 6 hour appointment window is totally asinine to begin with. And while I understand that delays happen, the lack of communication is completely unacceptable.
***Update***
I received a phone call from the company today. Apparently my phone number was listed in their system incorrectly. They acknowledged the mistake on their part and offered to extend my service plan free of charge. I appreciate the genuine effort at a service recovery, and will go forward hopeful that all goes well and I can continue supporting a local business.
Judith M.As my heating-air conditioning business owner has just retired, I will be looking forward to getting in contact King Heating, Cooling & Plumbing in the future for future needs.
Eduardo A.So I can understand the $100 fee for showing up and giving a diagnosis. But to change someone $295 for a starter (capacitor) that sells for $12.99 is a flat out robbery. So labor for a 20 min job is $280. I definitely recommend looking somewhere else. The technician did fast work and I have no complaints about him. But DO NOT LET THEM RIP YOU OFF.
I purchased a new A/C & furnace combo when my furnace broke down in the middle of winter. I was kind enough to allow them to install the units months apart in 2021 (furnace installed in Feb., A/C completed in Apr. or May) due to their own scheduling issues. I was promised a check-up on the A/C when summer came around to make sure everything was running properly. That never happened. They continually push for you to pay $100 for a service that was promised upon purchase. Summer 2022 rolls around & on the hottest day in years, my A/C won't cool my house below 75°. The unit is ~1 year old at this point and they refused to send a tech out to inspect without me agreeing to their service fee. Mind you, it's 100° outside and the A/C is blowing warm air into my home. A manager agreed to send out a technician while waiving the service fee. 20 hours later I finally get a call that a tech is on his way to inspect the issue, but that was never his intention. The pompous, freshman level tech only wished charge me for ""emergency service"" (20 hours after I called) to claim that the A/C coils were dirty and they needed to be cleaned. Without me agreeing to any service at this point, he grabbed ""tools"" (a hose & a spray bottle) and cleaned the outdoor A/C unit then wanted to charge me $195 claiming it to be an emergency. All while never addressing the underlying issue to begin with. The A/C unit still won't cool my home to desired temps and now the outdoor unit is making odd noises after his ""emergency service"". I recommend looking elsewhere when making these major home investments.
Northern Y.Called to get an estimate for a hose bib replacement. Told I would have to pay $99 to have the plumber stop by to give an estimate for the job. I asked for a ballpark number, I was told the plumber would need to look at the hose bib. Next....
James K.Well the 2,200.00 quote was way off. 30 yrs in the service business I never quoted some b/s to a customer. 4 season came out and laughed at what I told him was wrong. 550.00 later all done ?
