"They were able to attend to my air conditioning emergency within 24 hours of me calling which is great, but the service call was a bit high I thought. The technician, I think his name is Jeremy was very polite and seemed very knowledgeable."

"Customer service was excellent. Everyone from the person who first answered the phone to the guys who did the cleaning were friendly, professional, courteous, and thorough. We can tell the difference in the air quality already and our furnace sounds quieter too."

"Absolutely a great company to work with from all aspects. We had a large project to replace both the furnace and central AC systems, and also replace the main ductwork to create separately controlled ‘zones’ for the first and second floors. With the old system the second floor was always too hot in the summer. Through research on my own I had already decided on the highest level Bryant ‘Evolution’ units for both the furnace and AC and for the new zone control. The project was too large for the contractor we had been using to service the old units, so the search was on for a factory authorized Bryant dealer to install the new system. The choice of Square One was easy. Steve the owner came for the estimate, super knowledgeable about everything with the Evolution system including the details of the zone controls, and he prepared the proposal for us on the spot. I had originally intended to go through the usual hassle of getting at least three estimates, but I already had a ball park idea on the cost from my own research and after meeting with Steve there was no need to look any farther. Also we had a special request to relocate the intake/exhaust pipes of the old system to a difficult new location because we didn’t like where they exited on the side of the house, and Steve was happy to accommodate the request. I thought early September would be a good choice for the installation since would we probably would not need either the AC or furnace during the construction, but as bad-luck would have it a hot and humid wave of weather came right at the start date. Since the project was large it ran across four days and our crew of Jeremy and Josh did an outstanding job of minimizing the time that the AC was down, and gave us frequent updates on how things were going. They called every day when they were on the way, always came on time, friendly, knowledgeable, and super neat and orderly with all of the piping, ductwork, wiring and general work area. Co-owner Lee and Shaw came to finish up the intake/exhaust (on a Saturday) and did a fantastic job also. Also they prepared all of the paperwork for the multiple rebates that were included, and Erika and Mary in the office are always friendly and super responsive in answering our questions. The Bryant Evolution system has been great also, the hot and humid week turned out to be a good test for it and it performed excellently. The house has never been so comfortable upstairs prior to this system, and the new ‘dehumidify-only’ mode is great for the humid days without high temperature. Overall working with Square One was fantastic and greatly exceeded our expectations. They have all of our HVAC business from now on and we would highly recommend them to anyone."

FAQs for air conditioning projects in Fontana, 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.
