"THIS COMPANY IS SCAMMING PEOPLE!!! -On 6/24/21, Farnen and Dermer installed a brand new YORK HVAC system in my home. Everything appeared to be fine, and there were no issues for 2 years. -On 8/28/23, I noticed an extremely loud buzzing coming from my outside unit, so I called them to come check on the problem. My unit was still cooling, but extremely loud. Glen A. showed up to diagnose the problem and seemed like a nice enough guy. After about an hour, he informed me that my entire indoor and outdoor unit need full replacement for a total of $10,900. (I paid $7,500 just 2 years earlier). I said, surely this was covered under warranty because the unit was only 2 years old? He then informed me that it was not because it was â struck by lightning and the warranty does not cover an act of god. -At this point in my head things were not adding up, especially since the unit was still cooling, both of my neighbors units were fine (townhouse) and he did not even check the inside unit. I told Glen I need to think about the replacement because that is a lot of money that I do not have at the time. Glen disconnected my outside unit completely before he left with the hottest week of the summer upcoming (95F-98F) and charged me $189 for the visit. -I am lucky enough to have a Fire Marshall as a good friend to ask him about the situation. This guy sees lightning strikes pretty frequently. He told me there is no way that my unit was struck by lightning based off of what I was seeing and also because it would have gotten to all of my neighbors units (townhouse). He informed me it is literally impossible. THE UNIT WAS STILL COOLING! -I decided to get a 2nd opinion from another company. The other company came out and told me that my compressor was bad and that there was no lightning strike to speak of. They also informed me that it was covered under the warranty and they could fix it. The technician said that he noticed the wiring on the outside unit was incorrect. There was a red wire crossed with a black wire. He said that is exactly why my 2 year old compressor went out. This company even put their findings in writing for me. They replaced my parts and got me up and running for 82% LESS THAN F and D! -I am not the only person this has happened to. It appears to be standard practice. You can see the attached pictures of reviews from other people in the same boat on the Better Business Bureau website. I will be submitting a complaint through BBB and demanding a full refund. This is pure predatory behavior and it is unacceptable!"

"poor customer service. service manager insulted me, called me derogatory names while defaming my character. when all I was looking for was for someone to right a wrong. I was actually looking forward to them coming to look at my furnace and was hoping to find a trusted company but was given the complete opposite of what I expected. first no one called me with an update, I had to call, then no one showed by 5pm after I waited patiently all day during their 8-5 window. finally at 5:10 i reached out again only to be met with an after hours line that couldn't help me at all. once I spoke to SM, he insulted me, called me derogatory names and defamed my character all because I was understandably upset for being "brushed off" by everyone I had come into contact the entire day and given excuse after excuse with no solution that was going to benefit me. Customer service and professionalism are lacking 100%"

Heating and air conditioning services FAQs
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.
