"After a nightmare trying to get 2-10 Home Warranty to get their "qualified" contractor out with a week of mid 80's temps, I gave up and called Pro Heating & Cooling. This is the busiest time of the year, yet Cody called me back ASAP, and showed up the next morning early! He even called to tell me his ETA. A quick assessment and 4 lbs of freon later, we are cooling again. Great, professional services, and we will continue to utilize them in the future. ***I've also left reviews on AL for Rapps Heating and Air, as well as 2-10 Home Warranty as if you hear either of those two names, expect a hassle/scam and run the other way."

"Air today got me fixed up after my AC unit stopped working 18 months after install. When contacting the company that installed the unit, they openly admitted that the unit was installed incorrectly which caused the failure. After quoting us a seemingly high price to fix it, we looked at other options. We contacted Air Today and they got us fixed up quickly for a fraction of the cost! Not only was the cost better, the techs that came on site were knowledgeable and kind. Mark and Keith were thorough in explaining the issues and patient in helping us understand the needs. They recommended several different options to fix the issue at varying price points. The techs were respectful of our home and were careful not to make a mess or track dirt inside. We work with contractors frequently. Mark and Keith were top tier. All four Air Today employees we talked with through the process were helpful and easy to talk to. Would highly recommend Air Today to family and friends!"

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.
