"I had my 27-year-old furnace and a/c replaced by them. The entire process was effortless. Joe and John were great to deal with. The 2 techs that came out were very friendly and efficient. They had the whole project done in less than a day. The clean-up and explanation of the new system met and exceeded my expectations. The new furnace works great and is much quieter than the old one. We only had a chance to run the air for one day, and it also worked very well. I would highly recommend Air Comfort Heating and Air Conditioning for furnace and a/c replacement"

"The entire team at Air Pro was fantastic to work with. Matt called and updated me with any new information. My original project of converting my furnace from LP to natural gas was delayed due to some of their staff being sick, and Air Pro called me first thing in the morning to provide and update. They also rescheduled everything within the same week! I would recommend Air Pro to anyone! They did a great job!"

"Riley was the technician who serviced my air conditioner yesterday. Riley always kept me informed on the progress of the work he was doing and before leaving THOROUGHLY explained the condition of my air conditioner and what I can do to extend its life. Fortunately my air conditioner, even though it’s 11 years old, is in great condition and I plan on doing things to prolong its life. Overall I would give Riley a rating of 10. He is an exceptional technician, knows his job, explains things well, and personable. The cost today was $17 for a replacement filter."

"I had my air conditioner cleaned and technician Eric B. was excellent! While waiting for my air conditioner to kick in he offered to fill my water softener with salt. I was so appreciative of this kind gesture and it reconfirmed why I chose to buy my new furnace and air conditioner from B&D!"

"I highly recommend Thomas with Prolific Mechanical. Another company came out and told me I needed to replace my HVAC system, but I decided to get a second opinion. Thomas took the time to properly diagnose the issue and was able to repair it instead of pushing for a replacement. He saved me a significant amount of money, was honest, knowledgeable, and professional throughout the entire process. If you?re looking for someone you can trust, Prolific Mechanical is the company to call."

FAQs for air conditioning projects in Saint Michael, MN

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.
