I highly recommend TEMCO for all your heating and air conditioning needs. Tim Prusha and his entire…read moreteam are true professionals who consistently go above and beyond for their customers. They are reliable, responsive, and always there when you need them. A special thank you to Billy Farrell, who recently came out to repair the air conditioning system at my office. He quickly diagnosed the problem, explained everything clearly, and had it fixed in no time. His knowledge, professionalism, and attention to detail were outstanding. The personality, respect, and dedication that Tim and his team bring to their work speak volumes about why their company is so successful. It's refreshing to work with a company that genuinely cares about providing excellent service. If you're looking for an HVAC company you can trust, TEMCO is the one to call. They won't let you down! -- Scott Raymond Raymond Brothers Landscaping

What sets TEMCO apart from others is the character of the ownership and management. The company…read morelooks out for the best interests of the consumer, and honors courtesy, fairness and fair dealing above all else. Case in point when a faulty heater was installed years ago by another outfit. The owner Tim documented the issues, and problem solving attempts, and was able to navigate a warranty replacement with the manufacturer, and provide a speedy installation of a new heater at a reasonable cost. It's comforting to do business with a company of high ethical character. I also admire a local company that invests in teaching and training local young talent so one day they can serve their communities with the same skill and adherence to the high standards of ethical responsibility of the current ownership.

Let's face it, spending that $ for the stuff you cannot see is never fun but Rob gave a good fair price. His techs - Mark and Robert -were here all day and did not stop until job was done, checking to make sure it was working properly and explaining the system to us so it can function for years to come. They were cordial in working in masks in this trying time (and with us wearing them in our home as well to protect them). Removing the old furnace was a task in itself as it easily weighed OVER 500 lbs and had to be broken up in two pieces to get out of our basement! I had used DB prior to for our annual AC checks, but this is the first big time job and couldn't be happier. Great service all the way around.

Their estimator Chris arrived, took his time and explained what needed to be done. The estimate was fair. Office staff is nothing but wonderful who return calls!! Amazing. They actually work with you for installation in accordance with your schedule. Whalen and Ives sent a team of professionals to my home that were simply amazing; each and every technician carried out his task perfectly. Not a minute of time was wasted. They arrived on time, which was shocking in this day and age. And....they cleaned up! Obviously the Owners are smart to keep their crews happy. Bravo!

Told me that they got the unit going and put 2 lbs of freon in. Was told I need a new unit. A/C ran for 6 days and stopped working again. Called in someone else who told me that the reason my unit stopped running was that the coils were very dirty and needed to be cleaned. Freon was not the issue. He cleaned the coils and gave my unit a go over and told me I do not need a new unit. He stayed about 1 hour going over the unit and making sure everything was working properly. Charged me less than 1/2 of what I payed Allstate for less than 15 minutes of service. To add insult to injury I found out that I was overcharged for the 2 lbs of freon by Allstate ($450.00).

I called a different company with obviously a more technical know how and they said it was a leak the whole time. O'Neill didn't find it. Obviously they're hiring techs with very little capability.

Tech comes, hangs out a while, says I need a new flue sensor AND a barnd new external condensate pump (with tubing) Repairs 1600 dollars. After I picked my jaw up from the floor, I asked the owner if my estimate could delineate parts vs labor. He then proceeds to double talk me about "there is alot more involved than parts and labor" umm wat? He continues on that he has to buy gas, pay for insurance, 401k, workmans comp, a warehouse. Basically giving me the "no man in the house hustle". I call a competitor, independent diagnosis of flue sensor, gets part (that was like 100 bucks) and I have hot water again. Concerned about the condensate pump Smith said I needed, I asked the honest repair man and he laughed because IT WASN'T EVEN A PART OF MY SYSTEM anymore and had been bypassed. So instead of 1600 dollars, I paid 500 dollars. I know that at the end of the day Smith would have restored my hot water, but he was absolutely taking advantage of me. As a single parent, every dollar counts and 1100 dollars is a big deal for us. He was absolutely ready to take food off my table. So in closing, the five star rating is probably because most people dont know their ass from their elbow and blindly trust that a company isnt out to soak you. This is your fair warning. If you do call them, save yourself money and get a second opinion like I did. ​

I decided to call Clarkstown Heating & Air Conditioning based on two things: Seeing their trucks driving around Rockland County all the time, and positive online reviews stressing their professionalism, promptness, and honesty. It was a pleasure scheduling, from the polite office staff, to the confirmation call that my tech was on the way, to the actual appointment with my technician Randolph. Randolph, an energetic and polite young man, greeted me with a firm handshake, and friendly smile. He confirmed the job scope, and price, and got to work and diagnosed the problem, and immediately solved it! He also gave me a tutorial, based on the questions I was asking, on how to use my existing system more efficiently, how best to set each thermometer, and when and how to change air filters if / when I wanted to do it myself. I'm satisfied with my service, and hope my 2nd appointment later this week (for a separate issue) goes as well. I was charged $109.00 + tax for the AC Diagnostic Check.

Buyer Beware: Outrageous Pricing for Basic Repairs I am…read moreincredibly disappointed with Clarkstown Heating & Air Conditioning. My AC capacitor went out on a hot Friday, and I contacted them looking for a prompt repair. While the technician who arrived was professional, the billing was completely predatory. They charged me $685 plus tax to replace a single dual capacitor. This is a basic 30-minute job, and the high-end universal part they used costs under $100 retail. The standard market rate for this repair in Rockland County tops out around $350 to $450. Charging nearly $700 for a simple part swap is an extreme, unconscionable markup. There are plenty of honest, local HVAC professionals in our area who charge fair market rates. I will never use this company again, and I strongly advise other Rockland County homeowners to look elsewhere unless you want to be severely overcharged.
