"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,"

"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!"

Customers say: Super punctual

"They did a great job! Everyone that I contacted with the company during my experience was helpful and polite. They installed a new HVAC (furnace downstairs and a/c outside) and a hot water heater in a 135 year old house which is a challenge, but faced it no problem. When they offered suggestions to make the system run better by adding additional cold air returns, they really worked with me to make sure that I was happy with placement and the finished product.....I mean who wants extra unattractive vents in the floor?? but they really made it look great! They were my lowest bid of 6 others selected from Angie's List/Lowe's and Home Depot and when the work was done it was right on bid not a cent more! I would definitely do business with them again my new systems are running great and the house feels very comfortable now. Thanks guys!! "

FAQs for air conditioning projects in Carmel, 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.
