"ok except the shower install. Bad install wrong caulk used around tub, had to come back to replace about three weeks later. 8 months later caulk coming loose from tile around tub and small holes in it in other places. They came back to redo and I thought they had scratched my tub they would not come look at it (turned out I was wrong and apologized for it. Now grout coming out and caulk loose again, after many phone calls (4, we will call you back and 5, we will be there no one shows and no calls to explain why. They send a guy to do the caulk. not grout, more calls more no shows finally they send a person, with no experience to do the job. Was told they were bending over backward to please me when all they were doing was taking care of their mistakes they created. Ever time I question no show and no call was told a emergency came up and I wasn't priority (One bath house). This stuff should last for years and not just months."

"My Thermostat had a error code E1 and nothing worked anymore. I has a few estimates and I was shocked...then I called Chapin's and good that I did. He fixed the problem and everything was up and running for a fraction of all the other estimates. Thanks for that and I can highly recommend this company. I will definitely stay with them."
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.
