"Boni Ramirez was timely on visiting and providing a price quote. The project start was delayed a few day, which we expected as it was a small hardscape project. Much more timely than any other lower Delaware hardscape contractor we contacted in the past. We would use this firm again."

"I clicked on Major League and they got back to me almost immediately. Mike the owner actually came out and checked my system the next business day. Keep in mind we have had no heat for 6 weeks and we just purchased the home mid June. Yet my electric bill was $1200 last month and on track to be $1500 this month. At its highest this past summer the electric bill was $389…..mind you this is the highest. Come to find out the outside unit was running in air conditioning mode all winter taking the heat from the house. Mike was on tech line for quite some time and when it was said and done we had heat!!!! AMEN!! Tonight has been the best winter night we have had since we bought the house. Thank you Mike for your knowledge and most of all thank you for our heat tonight!! You will be getting referrals from here on out."

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.
