"I contacted Greg after I turned on the heater for the first time and noticed a burning smell coming from the ducts. While they were booked out three days in the future, Greg found a way to work us into the schedule the same day. Within hours, they had the problem diagnosed and had located the parts needed to fix it--all at a fair and reasonable cost. Additionally, they offered advice on how best to maintain our air conditioning unit. I would highly recommend them and will be calling them again with future work."

"We called Jay when our A/C stopped working last spring. He was quick to take a look at our existing unit and give us options for repair or replacement. We chose to replace due to the age of the Air Conditioner. We were able to choose from a variety of brands, and had one installed within a week. We felt he was fairly priced and very knowledgeable, and best of all - we stayed cool all Summer!"

FAQs for air conditioning projects in Rochester Hills, MI

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.
