"It was fine. We scheduled an agreeable date and the young man came out and ran all the checks that he needed to run on the air conditioning system so I would say that it was a very pleasant experience. It was $49 for each air conditioning unit. We have 2 handlers and it was actually $98. There were no problems. He was very helpful. I thought the price was very reasonable. According to what he said, everything is just fine. It seemed like he checked everything. Their professionalism was good."

"Overall, we were very satisfied with the knowledge and quality of work that Covenant LLC provided. We had Covenant LLC install a radon mitigation system for our basement. Initially my husband and I met with David for the estimate and consultation. David spent the time to explain how radon can get into the basement, what the system would look like, and how he was going to make sure it was working. After meeting with David at Covenant, we met with a competitor who were definitely not as knowledgeable, were not going to seal any of the cracks or holes in the foundation or even follow industry standard by venting through the roof of the house. The day of install the crew was personable and professional and if they had any questions, they asked. The 3" pipe that Covenant had to install to run through a closet and into the attic. In order to do this, they had to drill through the porcelain title floors and run through 3 shelves. They spent extra time to jig-saw cut the shelves around the pipes and they took special care not to crack any of the porcelain tiles and when finished it looked like it was built with the house. After completion, Covenant came back and tested the radon levels which were reduced to below their guarantee, which itself is orders of magnitude below the EPA limit. We were probably not the easiest clients to work with as we had Covenant move the roof penetration several times until the noise was completely unnoticeable. David was always polite and professional and he wouldn't be satisfied with the job until we were satisfied. We highly recommend Covenant Air to anyone who is considering these services."

"I joined Angie's List to find someone that worked on portable air conditioners.  My brother took the unit apart to get to the blower wheel - but he told me that he didn't think that he could get to the damaged part and even if he did, he wasn't sure he could put the unit back together.  My brother can fix anything, so when he gave up,  I knew that I needed a professional. I liked the reports posted for  "On Call Maintenance", so I called (on a  Saturday) & left a brief message about what I needed.   In a very short time, Steve returned my call & he told me he felt confident that he could replace the part & put the unit back together.  I ordered the blower wheel & received it on the following Wednesday.   I called Steve & made an appointment for the next day at 10AM.  Steve had the part replaced and the unit working within an hour.  He was professional, courteous,  punctual, & returned/answered all of my calls.  My unit works great & Steve even installed the hoses & weatherized the windows better than they were before.  I will definitely call on Steve in the future.  In fact, I have a plumbing problem in my kitchen - I think I'll call him now."

Jim was able to stop ComboFix  remotely right away and provide some instructions for returning my computer to its old self. I am really grateful because I thought it was about to crash. There was no charge!

FAQs for air conditioning projects in Flat Rock, AL

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
