"Patrick started servicing our Furnace and Central Air conditioning systems a few years ago. He is so efficient, pleasant, and easy to work with that we specifically asked for him now twice a year for our annual Heating system check and also annually for our Air-conditioning system check. This trip he also had a trainee with him, and did a great job of allowing the trainee to do the work, but carefully supervising at the same time. Highly recommend!"

"Found Scott through homesdvisor. We had installed a new Wi-Fi thermostat and it wasnâ t working. We had no heat and the house started to get cold. I called premium heating and cooling. Scott was out within the hour. He was quickly and easily able to fix our thermostat and get everything up and running again."

"Mamayek Heating was very proficient with their installation of whole house central air-conditioning in our 1896 year-old home which never had a unit in place. From start to finish, they accommodated our needs and schedule as well as leaving behind a nicely done project in working order. Thank you to the 3 Bobs for all their help!"

"Swimmingly. I interviewed quite a number of HVAC companies for this job by sending out an RPF (Request for Proposal), and Bob Mamayek was unquestionably the most thorough in his on-site evaluation. Installation crew was fantastic. This is a small shop, and it was a true pleasure to have a team of regular guys just getting the job done. I recommend them without reservation. I almost gave them a B for responsiveness because Bob doesn't do a lot of email, but I realized while typing that this would be completely unfair, for two reasons. A) Bob might not respond to email with email, but he did always respond with a phone call. Frankly, that is better on many counts. B) This ignores the amazing response to my RPF, which was both timely and thorough. So, really, this says more about my email-centric life than Mamayek's responsiveness."

"One Hour Heating & Conditioning was prompt arriving at the scheduled appointment time. My wife and I also appreciated receiving a message that the techs were on their way. Our techs Kyle and Jacob were friendly, professional, and knowledgeable. Arguably one of the most thorough annual checkups I have had since being in the home for 7 years and using some other services in the past. While both furnaces are well beyond their expected life, neither tried to "oversell" me and offered objective pros/cons to some repair options vs. replacement. I would highly recommend One Hour Heating & Conditioning."

"Very pleased with our new air conditioner installation. The salesman was very nice and explained everything to my satisfaction. The installers were efficient and knowledgeable as well. They showed up exactly on time and were finished earlier than I expected. Work areas were cleaned up, inside and out. Not even any metal shavings in the grass where the new ducting was cut. One of the nice gentlemen even explained the new thermostat they installed. I highly recommend Southport Home Services."

FAQs for air conditioning projects in Waukesha, 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.
