"Wonderful! They responded almost immediately and quickly identified the problem being in my wiring. An electrician had rewired some of the electrical panel and that was what had caused the air conditioner to quit working. I had called the electrician, but he couldn't help me. I was so impressed by McCormick Heating and Air diagnosing the problem and fixing the same day!"

"Quick and very seamless. Rueben was quick to respond, came out same night and gave me several options. Ended up having new heat and air installed. Prices were amazing, furnace and air were in within 2 days and all working well with no problems. Men who installed were professional, left everything clean. Installers were great at reaching out to discuss best location for air conditioning unit install. Prices were great, customer service great, work performed great!!"

"Let me start by saying that this was not an easy experience. Our furnace is not easily accessible in the crawlspace. However, Ernie and his son handled it well. I originally hired Ernie because we wanted a furnace tune-up. Just a simple replace the filter and do a quick cleanup procedure. Well...as it turned out, we ended having to replace almost the entire system as Ernie quickly discovered that the previous install was done in a very shoddy, cheap and even dangerous manner. Ernie worked with us through the purchase and finance process and afterwards, he and his son worked late into the nights to get our furnace up and running. It took a few tries and even some additional visits back, but Ernie was true to his word and the job was done right. Would highly recommend this business. Hard to find people with integrity, knowledge and also hard work ethic. 10/10 would 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.
