"Prompt, efficient, friendly service. It was a weekend - naturally, that's when things break down - and they were available to work on the HVAC the next morning. Appreciated the good communication and service. Good to know that I have them for future needs."

"Queen City Heating & Cooling was very informative from start to finish. Cole, the project manager, took his time and explained everything involved with new installation of Rheem Central Air System. Ben & Vincent worked from start to finish, keeping us informed and performed their work in the hottest of days of August. Richard arrived, got system up and going. Queen City is very professional, polite and answered all questions & concerns. I will defiantly use them for all my Heating & Cooling needs."

"Called them late last summer when my 19 year old condenser quit. They quickly gave me a quote for an whole new heat pump system. They were out the very next day and installed it very quickly. Had to remove the attic ladder to get the bigger unit in, but they left zero trace that anything had been done. I called them for a concern when it was below zero in the winter. Got an immediate response. (Turned out to not be a system issue at all) I can't recommend these folks enough. Price was fair, service was awesome. He even took the time to teach me about the new smart thermostat. It was just an all around great experience. Thank you!"

"Reed's was very prompt with their service and I am very pleased with the results. The trench at the deepest point was nearly 10 feet deep. When they filled the trench the result was very rocky and not smooth at all. The backhoe driver said to give it a couple of weeks to settle and then request they come back out to compact and smooth the area plus reinstall my clothesline pole that had to be removed to install the line. I requested yesterday afternoon for them to come out and finalize the job. They were here at 8:30 this morning. The site looks great, my clothesline pole is installed. In addition, Reed's hauled off a brush pile from my yard without my asking."

FAQs for air conditioning projects in Republic, 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.
