"Took three times to get it fixed completely. The first repairman had to replace a part and we thought that was all that was needed. The next day or so, water was on the floor again so I contacted Air Serve again. The next problem was a crack in a pan. One of the repairmen, Cliff, was able to keep water from continually dripping on the floor while we had to wait for a new part to come in. It worked quite well. When the part did come in, he did a lot of work to get the new part in. I would have to rate him excellent. The air conditioner is now working fine. Couldnt put an accurate price, because we pay American Home Shield every month and had to pay $75 for the first trip, $86 for the second and I believe $100 for the last trip. Some was not covered by American Home Shield."

"We found Ozark Heating and Cooling is now renamed Comfort Care Heating and Cooling, same address. We called them and explained the problem. They were at the house 2 days later. Our technician Sam was great. He found the air filter was not properly cleaned and may have added to our A/C problem. He cleaned up the condenser, checked the freon level and our A/C filter. He explained the problem and pointed out possible future problems with our 20 year old unit. Sam was very professional and fixed the problem in an hour. I would highly recommend this company for any A/C and heating problem. We will definitely use this company for our future A/C and heating needs."

"We were impressed they would travel to Lebanon, MO. They did an assessment of the Duct Cleaning and installation of a, iWave-R and gave us fair quote. Arrived promptly on the day of service. Explained what was to be done, approximate amount of time needed and it was all as stated. I was also appreciate of the assistance given to move a two larger items from under the vents. Would resoundingly recommend!"

"Tuesday, February 7, 2023, CW (Charles Waterman) of Commercial Home Services In Camdenton Missouri, installed a new thermostat for the furnace in my house in Eldon Missouri. After he had left the thermostat wasnâ t working correctly, so I called him the next day to see if he could return and take a look at it. Over the next few days I contacted him several times. Apparently he had a very busy week, but first thing Monday morning February 13, 2023 he called me back and said that he would go by the house that morning and take a look at the thermostat. He found the thermostat was working but the furnace had several problems which he informed me would be fairly expensive to repair. I have decided to replace the furnace which is over 30 years old with a heat pump. Charles has been courteous and very helpful. I appreciate what heâ s done for us and would recommend him."

"It ended up in a $500 deal.  They ended up finding mold in the air return so they ended up doing mold remediation and then they found more and I told them to just go ahead and do what needs to be done.  They seemed like they tried to up sell me a little bit. "

FAQs for air conditioning projects in Montreal, 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.
