"I originally had a serviceman from Wooldridge Heating, Air, and Electric to evaluate our noisy, wobbling ceiling fan. It took a 12 ft. step ladder to reach, which I'm not able to do myself, anymore. Once it was determined that the motor was going bad in the fan, I asked them to return and replace it with a new one we bought. They two workers sent were prompt, polite, and very efficient. They had the old fan down and the new one in place in less than an hour. That included transferring a remote control receiver into the new fan canopy. They even took away the old defective fan. Very good service and at a very reasonable cost."

"We wanted the main waterline from house to street, and hot water heater replaced. After reading reviews, we chose Wisler Plumbing and Heating to do this work. Wisler reached out daily in advance to let us know who was coming to perform the work. Each employee we met was very professional, responsive, and diligent with their duties. Davey provided us with a quote for this work. Hats off to Matt for replacing the water heater! The waterline was a difficult project, due to the location. Adam and Wes did an outstanding job, excavating, replacing the water line, and for their work on restoring our yard. We will definitely use Wisler Plumbing and Heating again for any projects we may have in the future!"

I noticed in our mail thing that we are due for service on our system to keep our warranty up; to do so we are actually going to do a maintenance contract with them  it is about $96 yearly, but they come out and do inspections and everything. The owner is the one who came out and gave us a quote. We had them replace another system which was nor working correctly so the first the thing they did was send someone to inspect the old system to see what were the problems. They fixed it on the spot for free and did not even charge us to come out. They were very nice, courteous and stayed in contact with us the entire time. They were very nice, professional and they got the job done in an efficient manner. They did not charge us an insane amount of money for it. We had a name brand system. It was a well worth investment to have it done right.

FAQs for air conditioning projects in Roanoke, VA

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.
