"Great Experience. I was concerned about the 22 yr age of our air conditioner able to keep working and wonder if a long wait time to get a product shipped like refrigerators last year, I called for a quote and within a week it was installed and working! Installers worked tirelessly until their work was done, clean and neat!"

"Sam was great. Had a extremely dirty system that would not function correctly or blow cold air. Had High Ridge Heating and Cooling here as he has done work before for me and parents. He took one look and stated we needed to replace entire a/c furnace unit for $3100. Told us it would cost about the same to clean. No way I could afford that so went on Angie's List to find someone and read Sam's review's. He came out and told me the cost at $425 to clean. Which was fantastic. He spent about 2 1/2 to 3 hours and did a wonderful job. Ended up paying total $625 once he was done and asked me before doing anything additional that would cost more. Also since our unit didn't have valves on system to reuse our refrigerant he had to put new in which was part of price increase. Sam, thanks so mich for not trying to take advantage."

"Excellent - Darrin was very prompt, courteous, and happy to answer my many questions. He showed and explained to me how to disassemble the the sink stopper hardware, so the sink stoppers could be removed. Also, he disconnected the drain elbow in each sink, and then removed the many years of built-up hair/whiskers/goo that had slowed the drains but couldn't be pushed out or dissolved with chemical drain cleaners without opening up the plumbing under the sinks. He was completely done with all three sinks in under an hour. The two outside freeze-proof faucets needed to be replaced because of their age and poor conditions. But because Darrin didn't have sufficient time reserved on this date to complete that work, he wrote an estimate up for the work and let me use my $50 credit (I had purchased a discounted Plumbing Service deal from Angie's List for $39.00) towards that visit, but he applied the discounted plumbing service call to this visit (as well as credited me the entire service call for the follow-up appointment, too)."

"The repairman came out on time and found the issue immediately. While he was capable of repairing my compressor, he recommended that I contact the manufacturer to take advantage of a warranty repair. His honesty and details for how to quickly engage the warranty service caught me by surprise, and I will not hesitate to call this company anytime I have an issue. I recommend this company."

FAQs for air conditioning projects in West Alton, MO

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.
