"I can't begin to speak more highly of George and the experience of hiring his company Honest and Fair Heating and Air to replace a full heating and air conditioning unit at my mother in laws house. I called and within a few short days a new system was up and running. The job was completed quickly, at the most reasonable price, and of the highest quality. I never felt oversold or under serviced in anyway. Hiring companies like Honest and Fair Heating and Air inspire me to find additional HVAC projects to have the chance to work with them again. I am sure I will be working with George again to install a zoning system at my place and whatever HVAC related I may need. If George could make copies of himself, the rest of the HVAC industry would be out of business!"

"They installed central heating and air in our home in 2025. They were efficient, did a excellent clean up, and friendly. They checked in a week after to make sure we were satisfied with the system and if we had any questions. We are extremely satisfied with the new system. The controls are easy to work and the system is very quiet and efficient."

"Huge thank you to Chris at Alt AC for getting our air conditioning going again. It was absolutely wonderful walking into our house and feeling a chill after 3 weeks of record heat. We know of at least 5 houses who lost their A/C during these heat waves. If you need A/C service, we recommend Alt AC. Chris is professional, communicates well, and wants to earn your 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.
