"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."

"Barry from Hubbs Heating & Air performed an AC Tune Up. He was friendly and professional, checked the unit, it's connections and drainage, the coolant pressures and gave me some tips for keeping it maintained. Scheduling the appointment with Keri in the office was easy and they were responsive and right on time. It "feels" like a great company and I would recommend them."

"Previously I had used Rod Poppe for our HVAC needs, however, when he retired he sold his business to Watkins.  When our air conditioning unit stopped running on Friday evening, I gave Watkins a call.  Since it was fairly late, their answering machine gave an option of leaving an emergency breakdown message or a regular message (which I chose due to the late hour).  On Saturday morning I gave them another call about 8:00 AM and left an emergency message since it was going to be a hot, muggy day and I needed the unit fixed ASAP.  I received a call back from Michael House, the on-call tech very quickly and by 9:30 he was at our house.  After doing a thorough analysis, he found a blown capacitor and low Freon level, but otherwise the 24+ year old unit was in good shape.  Michael was VERY professional, courteous, and thorough.  I would HIGHLY recommend Watkins for any HVAC work."

"Hauserâ s sales manager and the field tech were both Very polite, knowledgeable and clearly communicated in as much technical detail as I wanted the repairs they recommended and why. Our previous HVAC service provider had diagnosed loss of AC cooling as a compressor failure and had quoted compressor replacement at over $3500 or even recommended replacing the matched AC & Evap Coil unit costing $5-$7K depending on the efficiency chosen. I approached Hauser for a second opinion diagnosis for loss of AC cooling and they diagnosed it as a deteriorating but not failed compressor and had it running in half an hour with a new replacement run capacitor and an add-on electrical gizmo â compressor saverâ at total cost of under $400."

"Mr. DeSoto came and diagnosed the condition of my furnace and told me exactly what was wrong that needed to be fix. He provided me with a fairly priced estimate. He returned in a timely manner and completed the work. I couldn't have been more satisfied."

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.
