"We had a great experience with Four Seasons Heating & Air Conditioning during our recent replacement of our furnace and AC unit. They were very professional and completed the job on time and answered all of my questions. Would recommend them for our Heating, Air Conditioning, Plumbing and Electrical needs."

"It had been gradually getting warmer and this was one of the first days we wanted to use our AC unit this year. When I returned home from work it was very warm in our home. I called Craig with C2 Heating & Cooling who said he could be over in roughly 15 minutes. Craig worked for around an hour and half to find and diagnose the issue. Then went about fixing out AC unit to blow the coolest of air into our home.
Can not be more grateful for the speed and service offered by C2 Heating & Cooling. Will DEFINITELY use again should another issue arise.

"I recently purchased a home with an AC/Furnace that was not in working condition. As the summer months continued I needed air in my home to make it comfortable. I found Champion via Angis List and from the moment I spoke with David he not only kept his word but went over and beyond to ensure I was satisfied. If he said him or his team would show up at a certain time they showed up 15 minutes ahead of schedule. I never had to call or wonder where they were. They were also exceptionally fast. He came to my home on Wednesday for the consultation and my Friday my new AC & Furnace were installed. Outstanding service and a great team of folks. If you want quality service at an unbeatable price this is your team!"

"Regional Plumbing, heating and cooling came out and inspected my duct work, furnace/AC, my very hot upstairs and my thermostat. He gave me advice on how to cool the upstairs and several suggestions. He was very helpful and courteous. I could not afford any of their services and resorted to getting a window air conditioner installed. If I ever can afford them in the future I will gladly call them again."

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.
