"We have been waiting for a call back for over 2 weeks. We had a 4k job to ground our above round pool a month ago. We need the inspection certificate to pass the village inspection. It failed after the first try so the company sent someone else to fix the issue in order to be complaint with our village. We waited from 12p-9p for someone to show up. We received a call late that night that they couldn't come and would come the following day. The electrician finally came 7 days ago. He "fixed the issue". He stated we would receive the inspection shortly. The inspection company just "needed a picture" of the change to approve it. My husband has called Universe several times. Left several messages for the DOO with no response. He just got off the phone with a "Chris S" who says he is a project coordinator. He argued with my husband stating, "we are at the mercy of the inspection company". Universe chose this inspection company! We paid for it! Our village inspector is coming tomorrow (appointment made three weeks ago thinking this would be resolved) and we still have no electrical inspection. My husband had surgery Monday and is supposed to be healing. I NEVER write bad reviews..i try to resolve first but I have nowhere else to go. All I need is the inspection certificate! My next step will be to stop payment. UGH..what is so difficult here?"

"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."

"I was overcharged for replacing a shower faucet cartridge. The plumber inspected the leak and ask me to sign a quote for $600 - which he said would cover the labor for the removal of the old cartridge. He said he needs to melt it out with a torch and may take an hour or two to remove the old one. The $600 covers all labor and parts. I signed the quote. He open up the shower, removed the leaking cartridge and replace with a new one in 15 minutes. He stayed in the bathroom answering emails for 10 minutes because he was embarrassed - and when I confronted him - he said it came out easily - but still charged me $600 since I already signed the service agreement."

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.
