"Our ac died at about 8pm. We requested quoted online and through home advisor. Joseph called us first thing in the morning and said he could be out in an hour. He was, and he had told me what was needed within a half hour, with options, and then we had a working ac within the hour. Joseph was very prompt, very professional, and I would recommend him to anyone."

"My a/c hadn't worked for two days, it was 90 degrees in the house. our go to hvac company is comfort heating and air, we called them, and a gentlemen named Taylor Burton showed up and promptly got to work. He was able to fix the issue within 10 minutes. He told us what was wrong, and even changed the filter to the unit. I highly recommend this company. I've used them before for my hvac needs, and both times they were able to fix whatever problem I had. 5/5 stars."

FAQs for air conditioning projects in Lancaster, KY

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.
