"I called Cincinnati Heating and Air Conditioning to give me a second opinion on a cracked heat exchanger reported to me by a tech from Schneller/Knochelman. Cameron came out and thoroughly checked out the unit and informed me it was fine. CO levels normal. Not the 600+ ppm reported to me by the other tech. Even better than finding out I didn't need a new furnace or expensive repair there was NO CHARGE for a second opinion! Cincinnati Heating and Air Conditioning get my business going forward. They rock!"

"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."

"My expectations were exceeded during my furnace tune-up for the winter of 2021. My furnace is running a lot more efficient. The service technician was very professional and knowledgeable. He shared the condition of my system before and after the tune-up. I'm looking forward to lower heating bills as a result of all the adjustment made.

"Professional, prompt and I was very happy to get my repairs done. Tried the name brand SEARS and they could not fix their own appliance."
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.
