"I'm giving zero stars! I called All Star Heating and Air Conditioning to come out and check my AC. The reason I used them was becuase the sticker on my unit was for Dean Plumbing Heating & Cooling. Apparently, Dean sold to All Star. I told the repair man, Scott Owens when he arrived that the "box" (condensation removal pump) made a terrible noise and then the next morning the unit was no longer working. He was at my house for a total of 30 minutes not counting drive time and the amount of time he sat out in from of my house upon arrival and departure. Anyway, a condensation box was replaced and I was charged $618 WITH a membership discount. I know this part can be purchased for under $80 and it took them 5 minutes to rig it up. This company is abusing the public. DO NOT USE THEM. Please call a locally owned company that will give you an itemized statement upon request. I asked them for an itemized quote and they refused to give that to me. I find it hard to beleive that an hour total of work plus a part would categorize as a $618 bill. I beleive I was ripped off and taken advantage of. Hiller would be a better company to call becuase my neighbor used Hiller just last week for the same issue and they paid $240 for parts and labor. So save your pocket and call Hiller if you want a reputable service tech and reliable, honest company. If you LOVE getting ripped off call ALL STAR HEATING AND AIR CONDITIONING for all your HVAC needs becuase they are dishonest and they do NOT CARE ABOUT THIER CUSTOMERS. I googled the video of the replacement for this and I could have actually done it myself. I mean, I had already diagnosed the issue for the repair man Scott so I made his job easy. Or I guess I made it easier for them to rip me off. Please google and do research before chosing this company. Go to someone else. ***Update to a reply from Sabrina in the office -Question... Misty Pierce do you realize that these are two completely different parts and do different things? Reply... Sabrina Machera Nietzel yes I do. I’m referring to the detail in the invoice. The quality put into the invoice provided by Hiller is much better. And both parts/jobs are equal in time to repair. Just a different part. Google the video for both and you’ll see. Actually, the capacitor is a less expensive part but a little more time consuming/complicated to replace than what u had done and yet Hiller was able to still charge a much less price."

Full plumbing, Septic system service, Roofing and siding company, HVAC 24-7 365

"The company was prompt to respond to my original request for service. I thought that I would just need to have the septic tank emptied. I was told that the field lines needed to be replaced, and that possibly the septic tank would also have to be replaced. They did the work soon after the request. The quality of their work was very low. Here are the problems 1. They did not return the yard to previous state as promised. The original work including reseeding was completed in early March 2019. a month later I called and told them that the grass had not grown and that the area where they had worked was uneven. They then said that this was normal and they would come back and refill in the area. 2. When they refilled in the area they dug up several rocks. They removed some of them and placed them along my fence, near my garden area and other places they did not belong. They did a terrible job of leveling and filling in the area. It was almost worst than when they started. 3. I called several times and talked to Roger. He kept saying that he would come and take a look and get the problem taken care of. Finally he sent another person to report to him what the job looked like. I never heard back from Roger, so I called and left a message. Finally after several calls he returned my call and said that he would come on Thursday around 10:00 AM. He never showed up. I have also tried to get to talk to Jeff about the situation and the office assistant never gave the message to Jeff, or he does not care about the quality of work that his people perform. 4. There was another job that Roger had given me a quote on when he was originally working on the Septic system. He gave me a quoted offer and I said that would be fine. He said he would return next week to do the job and never showed up. 5. The last time I called Roger I told him that the septic tank area near the house had a leak and smelled terrible. He told me that this was normal. He never came to inspect. (I have checked and this is not normal despite what he thinks.) 6. It is going to cost me approximately another $1,200 to get my yard into decent shape thanks to the poor quality of their work. 6.In addition, the man who mows our yard hit a large exposed rock and it broke the mower blade. he has a large, commercial type mower, and had to pay to have the blade replaced. He now refuses to mow that part of the yard because of the rocks which were left on the surface.8.On the second attempt to complete their job they removed my raised garden, and raspberry plants which were in in a different area than the line fields."

FAQs for heating and air conditioning service projects in Oak Ridge, TN

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.
