"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!"

"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."

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

"I would highly recommend Droegkamp. I usually shop around for big purchases like this but since it was in the middle a heat wave and the pandemic, Droegkamp was the first company that could come to the house. They were very professional, gave me a few options for a new air conditioner, and filled the freon in my broken air conditioner so that I could have cold air until they could come and replace it. It was a few weeks before they could come and the freon ran out before they were able to replace the air conditioner, so they came and refilled the freon to tide me over. The gentleman who installed my air conditioner worked efficiently and completed the job very neatly. When I called the office on numerous occasions someone always answered. They were always courteous and if they couldn't answer my question, someone always called me back in a timely manner."

FAQs for air conditioning projects in Sussex, 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.
