"We had Chris replace a decades-old gas furnace and electric water heater, as well as install central air conditioning. We talked to a few professionals in HVAC, and Chris seemed to have encyclopedic knowledge of it all. At a very fair price, Chris spent two days having the old stuff professionally removed, getting the new stuff (AC) wired up, and all the new equipment installed. This was a problem-free project from start to finish, and we would strongly recommend Chris to anyone with similar needs."

"I HAVE A VERY OLD DRYER FROM 1975. I HAVE BEEN TOLD FROM OTHER "SO-CALLED" GREAT REPAIR COMPANIES THAT THEY ARE NOT ABLE TO FIX IT BECAUSE IT IS TOO OLD AND THOSE PARTS ARE NOT MADE ANYMORE. I AM SO GLAD I FOUND BERNARD AT BK APPLIANCES !! HE IS THE ONLY REPAIR MAN I NEED! HE FIXED MY VERY OLD DRYER AND KEEPS IT IN TOP RUNNING SHAPE !! NO NEED TO GET ALL STRESSED OUT WHEN YOUR APPLIANCES STOP WORKING, BECAUSE EVERYTHING IS GOING TO BE OK IN NO TIME, WHEN BERNARD GETS THERE TO TAKE CARE OF THE PROBLEM !"
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.
