"John and Daryl came on April 30th and did everything I had requested to repair my AC unit. We had a refrigerant leak which they searched for and repaired. They pressurized and vacuumed the system and recharged the unit. The return grill (ceiling cover of filter) was replaced and a preventative maintenance was done. A chemical coil cleaning was preformed. The unit is now working well and we are happy with the results. This work was done by Apex Air Solutions (listed as Chelsea Jenkins). "

"I never leave bad reviews but feel compelled to warn people not to use this man's service. The most unprofessional, short tempered and hostile man. I am a young mother with a 3 month old infant, so getting our hvac fixed is crucial. Vinny canceled on us last minute and rescheduled twice, he bad mouthed other companies who had worked on our system previously, he told us to run our own wires, and then called my father in law stupid for doing it wrong. When I interjected saying that that wasn't very nice and asked my father if we should call someone else, he became irate, yelled at me for saying something, said i ?should mind my business? in my own home, raised his voice loud enough to startle my infant and made him cry, said he ?should have pushed us down the stairs?, and stormed out of the house like a disgruntled prima-donna. The whole situation left me and my baby rattled. This man thinks that the demand for his trade entitles him to speak down to and mistreat customers.Go elsewhere."

"We had an ac unit put in two years ago. It never worked quite right. He came to check situation a couple times last summer - being it was a new unit - said to leave on auto/70 and should be fine. Still would not work correctly, hot days wouldn't work at all. This year was not working at all, only HOT air would come out. Once again came this summer, added more freon, stating there must be a leak somewhere. They couldn't find leak, told us we need to replace all the copper piping to fix the not even found leak. Wanted to charge insane amount money to fix a recent unit they installed that never worked in the first place! I tried calling the business a few times with not a single call back to speak with me. Thankfully i was forced to get it checked by someone else - it was an EASY fix! The flares were never tightened and there was a welded area that we were never told was done in first place. Do not trust this place; horrible customer service, unreliable, and afraid i was almost scammed!"

"I recently had the pleasure of working with Roberto and his team for all the plumbing work on my new construction project, and I could not be happier with the results.

"I am not a review writer at all, however, I felt it only fair to write a review for Eric and Just Rite HVAC after a wonderful experience. This company and Eric the owner are, in a word, the BEST! I needed main floorâ s central AC replaced. A friend recommended me to Eric. I texted him and he responded with a few hours. setting up an appointment was fast and easy. Eric was knowledgeable and timely. My job was extremely difficult based on the location of my air handler and there was a high chance the ceiling would need to be opened for access. When Eric arrived for the job he inspected further and said he was going to try not to have to open the ceiling for access. He and his crew went well beyond what anybody else would have done and meticulously dismantled the old air handler piece by piece. It was time consuming, difficult and energy consuming. But they were able to do and saved me from having a gaping hole in my ceiling. They did an excellent job setting up the new air handler in the same location and even fixed errors the previous installer had made! The entire crew were highly professional, courteous and clean. They put down drop cloths everywhere and cleaned up everything when they were done. I highly, highly, and without reservation, recommend Eric and Just Rite HVAC and will tell anybody I know about them."

FAQs for heating and air conditioning service projects in West Islip, 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.
