"I am very happy with the high quality work and professionalism of Opach's A/C & Heating. Opach's installed my new unit and they did a wonderful job. Opach's HVAC crew was very professional and as soon as they arrived they started working immediately. These guys are no nonsense and they appear to be experts at what they do. I really appreciate the fact that throughout the install they asked if we had questions. They also thoroughly inspected my entire unit. They replaced both the outdoor and indoor unit components. Opach's A/C also installed a new wireless thermostat. This thermostat allows us to check the temperature of the home when we are away and to adjust it while away as well. It also checks the weather. Opach's A/C & Heating staff and crew were very professional, and their services were competitively priced and they did a great job. I've had my unit for several days now and it's still working wonderfully. I will definately use Opach's A/C & Heating again."

"Another service came out and said I needed an $800+ fix. I called Aire Serv to get a second opinion and they not only stuck with it until they fixed my AC, (it took a couple Of visits but they only charged me for one) they did it without needing the expensive part the other one tried to sell me. They were very responsive, helpful and educational"

"I couldn't decide between a liquid cooled or air cooled generator at first. I decided on the liquid cooled so hopefully, there will be a lot less maintenance on it. It took about 2 weeks for the equipment to arrive, but it was installed and running quickly when it got here. The sales appointment was about as easy and low pressure as it gets. I'd call ATS again."

"Very pleased with the job done. Called up for a quote on a furnace and air conditioner replacement and sent a representative out very next day. Quote was exact price I paid and they didn't try selling me anything I didn't need. They were in and out in one day and everything has worked great. Would highly recommend."

"It went well. Removal and replacement of old, malfunctioning knob assemblies was fast and smooth, and sweep installation has eliminated a major draft. A second phase is planned because I could not acquire a storm door and some other parts in time to be installed with the new knobs, but Handymane is my first choice."

"We called JR HVAC Services to get a second opinion on our A/C unit not cooling. Brenton let me know when he was on the way to my house and also when he arrived. He was very respectful, which can be very rare nowadays, friendly, and knowledgeable. He looked at our A/C unit and found the problem and before he did anything, he went over what he found wrong with my husband and I and let us know how much it would cost before doing the work. Brenton was able to replace a part and get our unit cooling for less then $200 and the other company wanted to replace our unit and charge over $7000.00!! We are very pleased with this company and the service technician and the honesty."
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.
