"This is an excellent company. We have used them for year to service our heating and air conditioning units. It became necessary to think about replacing the units. We have two. Decided to replace both at the same time. They came out on a Monday and gave us an estimate and came out on Thursday and Friday to do the work. They totally cleaned up after themselves and made sure everything was working properly. Then they called a few days later to see that everything was working well. I highly recommend this company. All the technicians are polite and competent. The office staff is nice beyond belief. If you need any heating/AC work done, this is the company to do it."

"Showed up late, didn't install the bathroom fan as the manufacturer recommended (pic, fan5), dented the fan grille (pic, fan1). It was installed without the supplied support rails because he claimed he couldn't get in the attic. Now sure how I got the photos, then... The vent hose was kinked in the attic and hardly any air came out of the soffit, so I had to go into the attic to correct it. That's when I took the photos. Didn't give a price up front because apparently a bath fan with bluetooth speakers isn't in whatever book they price from. Not in the book? Overcharge. Generally very unhappy with the whole experience and will be looking elsewhere in the future. Not sure how when the customer supplies EVERYTHING but a romex clamp someone can charge so much. Absolutely unacceptable. $465 to have someone dent my fan, install it incorrectly, and throw out the parts that weren't used. Like the battery to the manufacturer supplied remote and the joist supports. I'm leaving the cost of service as originally quoted because it was only lowered to $465 after I complained about being ripped off."

"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."

"After several years of shoddy furnace repairs, replacements and guesswork from our propane provider, I decided to find another service. I quickly got a call back and appointment from Tetteris Heating and Air. After a brief diagnostic, Greg Shaeffer almost immediately assessed the problem was a malfunctioning gas valve. After replacing and converting the valve, he discovered that the old valve had not been installed or converted properly by the previous company. Greg was very professional, helpful, friendly and didn't mind answering any questions I had. I couldn't be more satisfied with the work and service that Tetteris provided. Highly recommended!"

"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.
