"Mike and his team did a great job with installation of a complete new HVAC system involving a ducted system on the 1st floor and mini splits on the 2nd floor (this set up best accommodated our house for function and zoning). Their experience and knowledge was demonstrated by their well planned work and installation, including working around existing conditions such as tight crawl spaces, as well as coordination with existing plumbing, electrical, structural components, etc. They coordinated and were accommodating of requests for equipment and vent locations. And they started and completed the work as promised. I would highly recommend them."

"Promptly returned email regarding service request, on Saturday. Responded same day to repair 2Ton Geo unit (Waterfurnace). Extremely knowable on geo-thermal systems, the repairs were made in timely manner at a fair price, my only regret on this geo unit is I should have had Continental install the system in the first place, it’s seems very likely I would not be haveing the maintenance issues."

FAQs for air conditioning projects in Cambridge, 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.
