We professionally install, service, maintain, and repair heating and air systems. We are a Carrier factory authorized dealer.

"A company with practices I would be cautious of. I am sure this company can provide great service supporting many of their reviews. Unfortunately, I had the experience that reflects another customers not so good service. I would like for potential customers to be made aware of what could happen. My father recommended this company to replace my a/c unit. The company quoted me $500 less than my local HVAC guy and could replace my non-working unit with a shorter wait time. I was very pleased with their quick installation and replacement of my upstairs unit. This service was done in November of 2020. The a/c wasn’t used much until Spring of 2021. At the beginning of August 2021 (roughly 5 months of a/c usage) I noticed a huge water stain on my ceiling. The carpet was soaked and there was a 10” bubble from which water was dripping. It was from my upstair a/c unit installed in my attic. I immediately turned my unit off. In the attic, there was water puddled on the left side under the wooden platform holding the unit. I questioned the water since the emergency pan was not full. Through further investigation, I noticed water dripping outside the emergency pan directly onto the subfloor from the duct coming out of the left side of the air handler. This is what was causing the water in the room below. I documented everything with pictures and video and contacted Premier Comfort Services the next morning. A technician arrived the following day. He was professional and courteous. He assessed the situation, determined the unit was not charged for summer conditions when it was installed last Fall causing the unit to “back pull”. He put refrigerant in the unit and assured me it would not leak anymore. When I asked if their company or Carrier would cover the ceiling damage, he took photos and advised his bosses would determine that. I placed a tube under the leaking duct incase it started leaking again. I received a voicemail from the technician about 30 mins after he left stating he cut the drains outside the house due to mud in them. When I called Premier Comfort Services after not receiving any communication for several days, the lady on the phone advised the damage would not be covered since the drain was clogged causing the pan to overflow. I communicated to the lady the pan had not overflowed as seen in the video I sent. There is a switch in my emergency pan that will shut my unit off if it was close to full which never happened either. I was told the owner would be contacting me to explain. I had not heard from the owner for several days even after leaving a message with them. Eventually he called and explained the emergency pan on the outside was not the overflowing pan. He said the pan on the inside was overflowing causing the unit to leak out of the "plenum" onto the wood and insulation. He said it was my responsibility to have the unit inspected every 6 months to make sure the drain line is not clogged. According to him, his company does not do attic installations where the air handler has to lay down (which is how my unit has to be because of the placement in the attic). I asked why the emergency pan was so small it did not cover this area that could leak. He said the code requirement is that the unit itself has to be covered by the emergency pan. I expressed my concern about the unit and advised this same problem could present itself and damage my house again. He said they were not local so they could not assist but to have a local company inspect the unit every 6 months. We ended the call there. At this point I had no confidence that this company would help with what seemed like a ticking time bomb in my attic, so I called a local company. The technician came the following day and was professional and courteous. He advised the drain coming from the pan inside the unit did not have a "T" on it to allow the line to be flushed. He installed the "T" and said he flushed the line to confirm it was working properly. I asked about my concerns with the same problem and ceiling damage happening in the future. He said they would suggest installing a float switch in the interior pan to kill the power if the interior pan overflows. He also said I could get a larger pan to catch drips outside of the unit. I asked them to do both. My issues with the way Premier Comfort Services handled my situation are as follows: 1. Why was the initial cause of the leaking advised as the unit was not charged for summer, but I was only told of the clogged drain lines by voicemail 30 minutes later after the technician found out there was damage I wanted to claim? 2. The owner advised they do not install air handlers which have to lay down. If that is the case, why did they do it at my house? If that is their policy, it seems they are aware this type of thing could happen. My 15 year old train unit that I had before this never had this type of issue. Why not inform the customer what to look out for if they do have a lay down unit. I only inspected the emergency pan and outside drain lines. The emergency pan was never close to full and the drain lines always expelled water. How would any normal person know to watch for water dripping outside of the emergency pan? Preventing water from dripping onto the subfloor seems to be the job of the emergency pan. 3. When I expressed my concern over this type of thing happening in the future, the only preventative measure offered was to have the unit inspected every 6 months. I don't think that would prevent anything since the a/c had only been used about 5 months since it was installed in the fall. They offered none of the preventative options that the local company offered. I would have definitely wanted an emergency float switch and larger pan if Premier Comfort Services explained why they don't install lay down units and the reasoning behind that policy. For anyone wondering, I also filed a complaint online with Carrier. At this point, four days later, I have heard anything. I will update the post if Carrier does respond. It seems that Premier Comfort Services' knows that Carrier air handling units have an issue if installed laying down. This makes me wary about Carrier products. When I have to replace my downstairs unit, I will be choosing a different manufacturer. I am cautious of a company who does not stand behind their work product. It seems, in my case, Premier Comfort Services did the minimum required. They took a chance and installed my air handler laying down, without any explanation of potential issues to watch out for. They did not offer an installed pan float switch or larger emergency pan when installing the unit. They only had excuses to cast any liability for the damage away from them. Is Premier Comfort Services operating in a manner which would make you comfortable when you have HVAC issues?"

Heating and air conditioning services FAQs

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified 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

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.

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.
