"The technician quickly diagnosed the problem. Since my HVAC system is close to 20 years old, he recommended consideration of a new unit rather than a costly repair. As a next step, I have a meeting scheduled with an Irish Air sales rep to discuss options,"

"One Hour Heating & Air Conditioning technician William B responded to our heating outage Saturday, Feb 27. He was very well prepared, knowledgeable, and dedicated to to analyzing the very complex series of problems. He basically disassembled the furnace and reset the air and gas flows. The furnace was still under warranty so there was no cost. We are most appreciative. He was so well trained and skilled. Would highly recommend William and One Hour."

Customers say: Super punctual

"They took out an oil furnace, put in an LP furnace and an air conditioning coil - they did quite a bit of work for the price. They were very responsive and very upfront. I?ve signed up a service agreement with them and they?re very punctual on it. I went with them because cost was a big thing. I would rate them highly and would recommend them to anybody."

"Dustin did an amazing installation of a new whole home heat pump system. The installation had critical attention to detail and Dustin provided a high level of understanding my needs in a system and matching me to the best solution. He was able to explain the reasoning behind the equipment and installation decisions. He cares about your project and went above and beyond making the install look pleasing. I highly recommend him for all HVAC needs in the future! A+"

"My heating/cooling unit was acting up and wouldn’t stop running, I was familiar with the company by seeing them at other homes in my neighborhood so I called and spoke with Ashley M. (They have 2 Ashley’s there) and she was able to get a technician scheduled to my home the next day for my repair. I was happy with the ease of the experience and the friendly demeanor that now I have a annual maintenance plan with them and when they come for my check ups, my dogs absolutely love them just like family and they love them right back."

"Realizing that your central air is continuously running is call for a check up. Service plus was easy to schedule and work with. Joe showed up in the window provided and most importantly he called to inform me of his arrival time. You will not find that with most companies. Joe showed up and discussed not only what all he would be doing but took the time to answer any questions or added advice to any issues or potential problems. Very pleased with both the customer service and with Joe the technician. professionalism and service is not lost with this company nor with Joe! Highly recommend"

FAQs for air conditioning projects in Mccordsville, IN

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.
