"In a word "Great". Even though the temperature was comfortable, the Krane representatives made a point of servicing our A/C system before this weekend....which is forecasting 80+ degrees. Daryl, our serviceman, contacted us to advise that he could arrive 11/2 hours early; which worked for us. He reviewed the compressor, check voltage levels and identified a problem with the low-voltage circuit; very professional and methodical. We then reviewed the furnace and upon removing the service panels he noticed a loose wire; a low voltage wire. Daryl reinstalled the wire and all systems were go. I forgot to mention, that he removed his shoes before entering our house; very considerate. He also checked the temperature differential between the air return and plenum ducts to verify the temperatures met average or better....AOK. Before closing the panels, Daryl reviewed interior of furnace to verify we had no additional service needs and gave us some recommendations on filters and settings. Overall, Daryl was very professional, systematic and friendly. We are very satisfied with Krane Heating and Cooling.

"As female investor seeking to hiring contractors that are transparent and have high integrity. I hit the jackpot with MIDPOINT COOL TEMP. Robert is passionate and genuine in his assessment and recommends "options to repair" vs immediately replacing a unit. Provided him a key to the vacant home, he got the heating system functioning, cleaned his area, and updated us promptly. FIVE STAR SERVICE all around!!"
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.
