"This was my first time using Cardinal Heating & Air Conditioning, and it was a fantastic experience. I received a phone call asking me if I wanted to schedule my annual air conditioning check, and when I said yes, the scheduler informed me that she could have a technician come out that day. The technician arrived within a couple of hours and did a thorough check. Everything checked out, and I am ready for the hot summer months."

"I had a very dirty a/c unit, and didn't want to clean it myself. Was afraid of damaging the fins, plus it hadn't been serviced for years prior to us purchasing this duplex. The gentleman arrived exactly on time. He cleaned it very well, then check the furnace filter which was also very dirty, replaced it. Also checked the R22 level, had to put a lb in and then checked the output of cold air. It was perfect. Told me the approximate age of unit and what to look for in the future. Highly recommended."

"We called Eli when our old humidifier started leaking. He came out that day to take a look and recommended a new unit to replace it since it was 22 years old. He returned a few days later and installed the Aprilaire unit and it works like a dream. I would recommend Eli for all of your heating and air repairs."

"Jonathan was great! My problem was misdiagnosed by a Sears technician assigned by Choice Home Warranty who could not figure out the problem for almost a month. I decided to look into Angi and found HERE HVAC with Jonathan and it was the best choice! Jonathan diagnosed and found the problem and fix my furnace in 3 hrs (got all the necessary parts and all) . He is also very nice and kind and someone I feel I can trust! The price was also really good and most important, he resolved the problem and explained everything to me in detail. Thank you Jonathan! My family is ready for the winter now :)"

FAQs for air conditioning projects in Poynette, WI

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.
