"Originally I called for a diagnostic of my AC unit, which was doing a terrible job cooling my house. Nikita did the diagnostic-turns out the coolant was leaking, a coil needed to be replaced, and not to mention the thing was from the 1990's. We decided to replace and upgrade it, as well as our furnace, since we froze last winter (turns out it was badly rusted on the inside and emitting CO into the house, which NO ONE found last winter (had it looked at by 4 different people and everyone said there was nothing wrong except that the BTU's were too small for the size of the house). Roy was so awesome, because even though they couldn't schedule us for the next 3 weeks, he made sure we stayed cool-he filled up the coolant and came over to the house a couple times when the AC stopped working. I will be keeping him as our heating and cooling guy!"

"Chris, the owner, was very knowledgeable about the type of furnace we needed, as well as could afford. He knew how big it should be for the size of the house. We have been using it this winter and even in the coldest period, it kept the temperature perfect. Chris did the install in minimal time and with professionalism. He even put in a flap, so that if we wanted to use our wood furnace it would close off the gas furnace flu, so the electronics would not overheat. We were very comfortable with him in our home."

FAQs for air conditioning projects in Knightstown, 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.
