"We had Chris replace a decades-old gas furnace and electric water heater, as well as install central air conditioning. We talked to a few professionals in HVAC, and Chris seemed to have encyclopedic knowledge of it all. At a very fair price, Chris spent two days having the old stuff professionally removed, getting the new stuff (AC) wired up, and all the new equipment installed. This was a problem-free project from start to finish, and we would strongly recommend Chris to anyone with similar needs."

"Majic Air did a great job of listening to our desires. We wanted to install central air conditioning in our two story home. We did not want ductless wall units. Shawn, the salesman, was able to come up with a plan that combined traditional ducted AC for the first floor of our home with ductless ceiling cassettes for the second floor of our home, completed with one wall unit for our finished third floor office. We have the air conditioning we wanted and the look we desired. The installers were professional, hard-working, and incredibly neat - leaving us with a tidy home each day. This was a complex job, and Majic Air got it done."

"H L Bowman is by far one of the best service companies that I have dealt with. I got a call that the technician was on the way to my house. George showed up and got right to work. Found my problem and explained to me the best way to fix my issue. They did not try to sell me on any pricier fixes. George showed me what he could offer and explained what would be my best option. He was knowledgeable, informative, and explained everything so that I would understand what was going on. I am definitely going to be using them for all my heating and air conditioning needs. Top notch company. Would recommend to anyone needing this kind of help."

"My AC wasn't blowing cold air. Bernard & his assistant came within a couple hours, diagnosed the problem and had my AC back to normal by the middle of the afternoon. It's been working great since then. Both men were very polite, patient and helpful. Would definitely use them again."

""I recently had my HVAC system serviced, and I couldn't be more impressed. Michael McGinn was extremely knowledgeable and skilled, diagnosing and fixing the issues quickly. He explained the process clearly, provided helpful advice, and ensured everything was working perfectly before leaving. His professionalism, attention to detail, and friendly approach made the experience stress-free and reassuring. I highly recommend their services to anyone looking for reliable and expert HVAC care.""
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.
