"I was experiencing low water flow to my 3rd floor bedroom. Since the house is 100 years old, I assumed that the only way to repair the problem was to replace the water service lines which would have been very expensive. Brian came to the house and identified the source of the problem as the water pressure regulator. Brian replaced the regulator, drained and refilled the lines to remove air bubbles. The problem was repaired. Given the age of the house and the location of the problem most contractors would have told me I needed to replace the pipes to the 3rd floor. Brian identified the real problem and in the process saved me a lot of money. Great Job."

"Our central air unit quit working late last night. I searched for a repair person, this morning, on Angie's list, selected AJB. They contacted me within minutes, texted back and forth, was told that they could be out this afternoon. They just left here, the unit is working fine. I am very pleased with the service and advice on our very old system. I would definitely use them again."

"Forest Hill Heating and & Air has been instrumental fixing/maintaining our 20+ year old heat pump both in the summer and winter months! We have also been fortunate to have them recently replace our water heater with a greatly improved unit - and have had zero issues with it since the day it was installed several years ago. I am looking forward to having another 20 year old water heater replaced in the near future by this excellent and professional business."

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.
