"It cost a lot , it was on a weekend and we did not have a lot of choice. They came out, they were prompt. It was on a weekend and so, I had to pay through the nose for the service call. I had them recharge the system to find out where the leak was. The price was average. They did good work, we didn't have to have them back again. for responsiveness, they were good. They came out within 2 hours from when I called. They were punctual. We don't live there anymore but if we still lived in that area, I would call them back. It was a good experience. It took a couple of hours. the service technician was good. They did a good job, we didn't have to have them back."

"Had an appointment for annual maintenance checkup. The Horizon tech was ontime, neat and polite. He checked all the routine items and resolved all of my concerns. He made a couple of recommendations for cleaner air circulation. All services were performed on my maintenance contract for no charge. This is the second heatpump that I've purchased from Horizon."

FAQs for air conditioning projects in Elk Mills, MD

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.
