"We had been going with the guys who installed our new furnace, but they weren't returning our calls and giving us the run around. I researched different places online and Aire Serv had the best reviews. The reviews weren't wrong. They got back to me promptly, worked around our schedule. Called if/when they were running late. The guy who came to check our furnace out was very nice and descriptive. Just all around great service, I would recommend them to anyone."

Hello, My Name is Johnathan Steele, Owner Operator of Show-Me Comfort Heating and Air Conditioning.

"When our heat pump went out I did, like the majority of owners would do to secure HVAC bids is google the local listings. I did and one of the bids secured came from Hansman Heating and Cooling. During the process of securing bids the owner came in not as the lowest but one that was associated with the Ameren rebate program. As a result with the rebate, the effective cost was lower than the other bidders plus the company was recommended by Ameren. In an area of unpredictable labor service and summer time weather(it seems that everyone needs cooling service), I was very pleased with his professionalism in his work ethic and by showing up as slated. I was impressed that they took time to explain everything, the quality of workmanship and the way they cleaned up after themselves. I would recommend them to anyone in the lake area."

FAQs for air conditioning projects in Jefferson City, 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.
