"The salesman from Extreme One Hour Heating and Air Conditioning, Michael gave me the best price, and I felt he is sincere, so I chose to use this company to replace the Heating & A/C. At 2018-09-06, Michael, Shaun and another guy showed up for the installation. I paid for an XV series Furnace, but the furnace they brought to my home is XR 16. I was told the internal is indeed a XV furnace, but the door is XR 16 door. They already showed up at my door, so I decided to accept it whether it is the wrong furnace or not. Michael, the sales man said that he will replace the wrong furnace door with a right furnace door. But after the installation, he never contacted me again. Shaun and the other guy did the installation, and they had really good attitude, and I appreciate that. Overall, the experience is not too bad. But the wrong door they installed always makes me suspect if they installed the right furnace that I paid for or not."

"This is a follow up to my new heat pump installation in 12/2022. Everything is working great. The variable stage heat pump costs more, but it is much better than my old, basic single stage. The air handler was in my office closet, so I spent the day working from home with them working in the same room. Funny and honest techs...I actually enjoyed seeing the entire install while doing my own work. I highly recommend them!"

"They did a great job, even noticed the original installer if the HVAC (a local company that is not good) basically slapped everything together. We had poor air flow to the second level, humidity issues, he helped us with all of that. He installed the air cleaner as they stated they would - they even took are of some warranty work/ parts when the unit failed. Good experience with a good group of HVAC professionals.

"Mr. DeSoto did an outstanding job replacing two thru the wall air conditioning units at my home. He found two units that were available and had them installed within 24 hours. He is very customer oriented, well organized, prompt and value oriented. I would recommend him for any heating/cooling work you my need."

"Riley did a great job on a new gas furnace and air conditioner install. I was very impressed from start to finish. He was on time, professional and answered every one of my questions. My system was about 15 years old and I have had to put some money into over the years. I used several other companies during that time and none of them, I mean absolutely none of them, compared to the process I just went through with TrueTemp Heating and Cooling. Everything from the service call, to the consultation process and the installation of my new HVAC equipment was top notch. Can?t recommend this experience enough! Thanks TrueTemp!"

FAQs for air conditioning projects in Dayton, OH

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.
