"Woke up around midnight to my HVAC being set to 75°, but all the temperature sensors in my home reporting above 83. So in a panic I reached out to all the AC places in the near area. Novation can in clutch. There were able to come out first thing in the morning after I dropped my kids off and school and their prices were a cheaper than most of the other quotes I received. I really appreciate Jackson. He showed up replaced the capacitor, found and fixed a leak in the copper pipes, and completely recharged the system."

"Marcus is incredibly professional and personable. He fully explained the problem with my furnace in a way that was easily understandable. He located the part he needed, went and got it, and returned here in good time. He fixed my furnace and it is now working like new. Marcus is an asset to ABC. I also, as always, am impressed with and happy with service I received from ABC. They tell you up front what it is going to cost you and there are never any surprise fees. I would never use anyone other than ABC to maintain or repair my furnace, air conditioning, or plumbing."

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.
