"I was having a problem with my air conditioning. The thermostat was blank. I called Ray?s HVAC. They came over and identified the problem. Then they came back two days later and fixed it. Everything is working fine now. I would use them again and recommend them to people I know."

"I hired Air Quality HVAC LLC to replace an old Central Air Conditioning unit that hadn't worked in years. Art the owner, showed up on time for the scheduled appointment. He inspected my old A/C unit, and discussed my options for replacement. Art was professional, knowledgeable and personable. He installed the new A/C unit and replaced the damaged duct work. As requested, he also installed a new thermostat. He cleaned up after the installations, and made sure that both the A/C unit and thermostat were working correctly. I'm completely satisfied with Air Quality HVAC, and highly recommend them."

"A faulty compressor required replacing, but I was informed it was not worth it, and they would only do a complete AC system change, at a price $500 more than any other company in the area. I asked for a repair service, not a replacement service"

"Peter was awesome. He replaced both my heating and cooling components and explained step by step what the work entailed, provided additional details on how the HVAC system works and what to do to take preventative maintenance measures so the system runs more efficiently and lasts longer.. He even corrected errors from the previous contractor at no extra cost and he was the most economical quote I received to begin with. Would absolutely recommend him for any of your HVAC needs."

"we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years. They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr.
We are very happy.

"High quality, responsive, fair, and clean These guys are the best! We worked with them on a water heater replacement and a air conditioner repair/replacement - both in July 2019. When our water heater broke, we called several places. They were the first to respond - Ahmad was able to come out to our house within an hour or so. He answered our questions, let us know why he knew it needed to be replaced (as opposed to repairing a link), and began working. He noted that our previous water heater had been installed incorrectly, and he re-welded a pipe so that the new water heater could be installed on a more level surface. While he was at our house, we asked if he could also install a new kitchen faucet that we had been meaning to replace. He was able to fix it in 20 minutes. For both repairs, he left the worksite clean. I'm glad our water heater broke that day, because we learned they also do air conditioner repair. Dean was much more knowledgeable and provided us with more repair options than any other company we had contacted. We had been under the impression that both our air handler and condenser needed to be replaced, but he let us know that although the condenser needed to be replaced, only one part of the air handler - the coil - needed to be replaced. This saved us thousands of dollars. Dean also patiently answered our questions about other air conditioner options we were considering (e.g., whether to get a a unit with greater capacity). While we were waiting for parts to be available, they did a temporary fix of our old air conditioner so that we didn't melt during the heat wave. On the day of the repair, everything went smoothly - they kept me informed about progress and cleaned up after themselves. I'll definitely call Green Apple the next time I have a plumbing or HVAC issue!"

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.
