"No Frost Air Conditioning and Heat came out right away to evaluate the unit. It turned out to be fine, but I was relieved that they were able to respond quickly. It was a very cold day and if the unit was running on the emergency electric, it would have been very costly. The service man, Clint, was very professional and polite. He did an excellent job of testing the unit to make sure it was running correctly."

"I signed up to have one of my HVAC's covered by Tim Kyle. I used the electrical service for over 20 years and the service is exemplary. This is the first time I used the HVAC service. I was impressed. It was a great job performed by a knowledgeable, pleasant tech who was available to answer any questions I had. Most important the HVAC was up and running before the 100 degree days to come later this week. Thanks guys"

"Dave the Tech was great. He called ahead to let me know he would be here in about 15 minutes and he arrived in the 15 minutes. He was courtesy and helpful and checked the unit inside and out. He explained every thing he was doing and what he found and how it could be fixed. Dave even took the time to talk to my husband over the phone on the issues he was finding. It was quite clear that Dave knew his stuff. I highly recommend Beltway Air Conditioning and Heating, LLC. I am definitely keeping their number by my phone."

"My experience with him was top notch. He was accommodating to my schedule. I work nights and he was willing to come to my home in the early evening instead of normal business hours. He assured me the fix of the leak would hold until the end of summer but there was a chance that I may need a new unit next summer since the unit is over 10 years old and the leak was pretty severe. I had no other trouble with the unit the rest of the summer. His price was reasonable and he was friendly and efficienct. If I need a new unit next summer I will definitely use Tetteris Heating and Air for the replacement."

"I am happy to write this review about JDL HVAC Services LLC. From start to finish; Amber, who setup my initial appointment was very nice & professional. Ire, the technical associate was prompt, very knowledgeable and got my system working again with a temporary fix. I opted for a new heating unit (which was reasonably priced) and all of the technical associates were easy-going and very professional. They were organized, used protective foot coverings and protective coverings for my floors, and cleaned up after the job. Special thanks to the entire team led by Armando; Jerel, Fernando, Michael, & Conrad. NOW, thanks to JDL HVAC, I FINALLY have a properly installed & functioning heating/air conditioning unit. I highly recommend this company!"

"Misunderstanding between Blue Dot and Baltimore County on the inspection.The unit was not installed according to Baltimore county code. Inspection has failed twice. Unit needs to be 3 feet from connection box. They have come out a couple times since the inspection has failed but the issue has not be resolved. It was clearly explained by Baltimore county what needed to be done. I always initiate the calls with them regarding this issue. I did not feel as if they are taking my situation seriously and I would not work them again. I was not advised I was being charged $75 to pay Baltimore County to inspect the Air Condition install. Promised by Jeff, supposedly, a manager a Rep would be at my house in 20 minutes on 12/17/19, no one showed. Jeff acted confused wanted to take a photo so he could figure out what needed to be done to move an Air Conditioning unit 3 ft from connector. Company trades under Blue Dot HVAC. Richard was very friendly and helpful with accommodating the codes for the County."

"We had a leak in the underground water supply line (polyblue) running from the County connection valve in the front yard to our townhouse. When I noticed the problem, the water was going all over the neighbor's yard. I called Heil Plumbing around 5:30PM that day and though their office was closed, I dialed their emergency contact number and reached Tom. He gave me the County utilities emergency number to call to get the service turned off, and that he will call back with a time for someone to come out. He then called back within a half hour to say Mr. Heil would be able to come that evening to give an estimate. Mr. Heil drove up around 7PM and gave me an estimate that was about two-thirds of what my immediate neighbor was quoted for the same issue about 6 months ago - to replace the existing leaking polyblue line with 3/4" copper, which was the best option rather than trying to repair the polyblue, which would only leak again. We had about 25 feet of line to replace, at a depth of about 5-6 feet. He also said at the time that the quote would be $700 more if they had to break/replace the concrete porch. I asked him to go ahead and complete the work as soon as possible since we were without water by then. Mr. Heil stated that they would be able to come out the next morning by 8AM at the latest.
The next morning at 7:45AM a crew of three arrived with a backhoe, dump truck, plumbing truck and air compressor (I assumed for a jack hammer if they had to break up concrete and for tamping soil). They had a contract written up for the exact quote given earlier. Once I had signed, they hand dug two small pits, one by the house foundation, the other by the County meter valve. They used plywood sheets to put the excavated soil on, which saved the rest of the yard grass. Luckily for me they didn't have to break any concrete. They located the two ends of the leaking polyblue line, pulled a steel cable through it, and then using the backhoe bucket and some equipment, pulled through the new copper line while pulling out the old plastic line. Then the new copper line was connected to the copper line coming out of the house and to the meter valve box. They then turned on the water and checked all the inside faucets. The kitchen faucet sprayer head was somehow blown out by the air being forced out when they turned the water on, and they replaced that free of charge. They then filled in the soil, compacting soil lifts with a tamper as they should, seeded and mulched the top of the disturbed area, and cleaned everything up. Took away a little bit of extra soil. Everything was done by 12.30 PM. They charged only what they had estimated, and like I said before, even replaced a faucet piece that came off when the water was turned on, free of charge. I was very impressed with the professionalism, promptness and quality of work shown by Joseph Heil Company, and recommend them very highly. I not only saved almost $1000 because their fee was low, I also saved a few hundred more I would have had to spend on hotel rooms if they had not been so prompt.

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.
