"Home AC went out when it was 90 degrees outside. BESCO Air came out the next day and Voila! Problem found and fixed. I've used these guys for years for both heating and AC. When other companies don't have the resources to respond promptly, BESCO comes through for me. With them, loyalty still matters."

"Home Comfort Systems replaced my old air conditioner with a new American Standard air conditioner. The day it was going to be installed, one of the owners, Steve, stopped by to look at the old air conditioner, and explain what was going to be done. The installers arrived an hour later, explained to me exactly what they were going to do, and all the specs of the new air conditioner. Roughly 2 hours later, they were finished. They explained the warranty, and cleaned up. The only evidence that they were there was the new air conditioner, no debris left behind. They were very professional, and I would gladly use them again!"

John and his assistent scheduled an installation time, showed up with the new, removed and disposed of the old unit, and were very professional (finished within the time the said, cleaned up any mess they made, and were happy to explain what they were doing) about the installation of the new unit.

"The man that came out was prompt . He fixed the problem for a fair price.i had a guy come out before him and he told me I needed a new system. It didnâ t make sense because my air system was just installed in 2018. I appreciate his accuracy identifying the problem. I have already reffered him to others"

From the moment I called, they showed complete respect for my time and scheduled the appointment at my convenience. They arrived right on time, and their team was not only professional but also incredibly courteous and clean, leaving no mess behind. What impressed me the most was their communication. They kept me informed every step of the way, providing updates on the progress and making sure I understood what was being done. Their honesty and transparency were refreshing—they honored every coupon without hesitation and offered fair pricing for top-notch service. It’s rare to find a company that combines timeliness, cleanliness, and a genuine commitment to customer satisfaction so seamlessly. I will definitely be calling Hot Cold Air again for any HVAC needs. Highly recommend!"

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.
