Please do not use the CALL button on this page. Call 585 377 3177 for faster service. ALL CALLS ARE $79.95 PLUS PARTS PLUS TAXES. Most Appliance repairs are $79.95 labor and trip and parts plus tax extra. Installations of dishwashers and microwaves are $149.95 plus parts plus tax. Disposals and waterlines for ice makers are $99.95 plus parts and tax. Gas lines and sump pumps are by free estimates. Dryer vent cleaning $79.95 Dryer vent replacement $79.95 -$99.95 plus parts and tax. hi Most calls are done the same day depending what time you call and calls are scheduled for AM between 9-1 or PM between 12-5. I DO NOT WORK ON FRONT-LOADING OR HIGH EFFICIENCY TOP LOADING WASHERS OR COMPUTER CONTROLLED DRYERS OR REFRIGERATION, TELL MY SECRETARY LISA IF YOU HAVE A COMPUTER CONTROLLED UNIT AND SHE WILL INSTRUCT YOU FROM THERE. I also DO NOT do any type of refrigerator work !!!!!! Except ice maker water lines. I would like to clarify something about my pricing structure. For appliance repairs I charge $79.95 plus parts and tax and that includes the trip charge to your home, the diagnosis and the repair. If I cannot repair your Appliance the fee is the same because it's still cost me to come to your house and diagnose your machine. I am basically fixing your Appliance for FREE. Other companies will charge you a service call to come out to your house and then they will charge you a diagnostics fee and then they will charge you a labor fee. That can add up to who-knows-what? I understand why everyone asked how much is this going to cost me? With my company you don't need to ask you will already know. The parts of course are what they are. And there is no upcharge on those parts. So I don't make it back on selling you expensive parts. I know that Appliance companies get a bad rap because of the things that they've done and still do. I have never done that I have been in this business for 48 years and have always charged a flat rate fee. So I just wanted to clarify that issue so that you have a better understanding, so you know what the fees are going to be if there are no parts involved. There is no fine print. This is how I do business. :-)

"Clothes dryer was not heating. Rod recognized the problem and fixed it promptly. He also diagnosed an additional issue, namely that the wheels/rollers that turned the drum were shot and needed replacement. All work was done promptly for a reasonable amount. Very happy with the result and would use him again."

"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day.

Keeping you safe, comfortable, and efficient. We are a family owned and operated business with over 30 years experience in the heating and cooling profession. We are indoor air quality specialists able to meet all of your heating, cooling and air quality needs. Our customer's concerns are highly valued and we look forward to creating a solution that exceeds our customer’s expectations. We are only a phone call away. Additional email - [email protected]. Award winning.

"I'd been a customer of Excellent Air for over 10 years and during that time they had been reasonably priced and competent. However, in 2019 I noticed that the upper level of my home (I have a 3-zone system) was not cooling properly. They refused to address the issue and instead blamed the Nest thermostat I'd installed myself. It seems that if you install anything on your own, they're not interested in addressing issues. This issue went on for a year and when I expressed frustration with the situation, they basically said they didn't want me as a customer any more. I hired another HVAC company (JJB Mechanical) and they were quickly able to determine that the problem was a broken damper on the upstairs zone. What really irks me is that the guy from Excellent Air noticed that the cover for that damper motor was loose, so he just reattached it rather than actually checking the motor itself. So, I chalk it up to either laziness or incompetence. The bottom line is that for over a decade Excellent Air provided me with quality service. But to drop me as a customer over something that they should have been able to easily detect and fix speaks very poorly of either their newer technicians or corporate policy."

When it comes to heating and cooling your home, you’re not just buying a furnace or air conditioning unit; you’re buying a company, a customer service team, the quality and integrity they represent. Whether it’s an emergency repair, an upgrade or replacement, or a brand-new installation, it’s the total experience that counts, and that’s where Isaac excels! Whatever your situation, Isaac’s highly trained professionals will educate you about your options and help you decide which solution is best for your needs and budget. We’ve been part of the local community for more than 70 years. And we’re proud to stand behind our heating and air conditioning products and our work.

"Use literally anyone but Isaacs. They will take $50k+ of your money and leave you with inoperable, disfunctional heating/ac throughout your entire house. Then do absolutely nothing to help you. They will say over and over how they will make it right. When in reality they will do absolutely nothing to fix the problem. It has been nothing but a nightmare trying to work with Isaacs. I could not regret hiring them more. It's been 6 months of pure torture."

FAQs for heating and air conditioning service projects in Clarendon, NY

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
