"My chest freezer broke down and I did not want to buy a new one since I could not afford the same size. I reached out to appliance parts pro and they were confident that what I ordered would fix my problem. $200 in parts later and I now have a broken freezer on my porch and am still paying the loan to this terrible company. They just want you to order parts and try them because they know you can't return them. I hate this company with every fiber of my being and will make sure that anyone that has a broken appliance will not use them. To top it off, their site is so screwed up that it give you an error trying to log back in.

Duct cleaning isn’t something that people think about often. Usually, duct cleaning specialists are called after something bad has been found; in most cases, the Dirty Ducts Cleaning experts are called because we are needed for asbestos removal, mold removal, or lead paint removal. Duct cleaning requires special equipment and training and when you call Dirty Ducts, you are getting the duct cleaning specialists known throughout Dane County, Wisconsin and the entire Midwest! Dirty Ducts Cleaning offers exceptional quality and value with our expertise. It doesn’t matter if you need duct cleaning for your home, your business or a large industrial area; Dirty Ducts Cleaning is here for you.

"Very well. The process was smooth, 50% down for the cost. A bit of a wide gap between order and performance of work, but that is a sign of a busy and healthy company. In the house, while wrangling my Cats, they worked with me to distance in one room until the first area was cleared, knock, vacate, and allow me to move to the completed area before resuming work. Wore a mask, wore house shoes, described the process and when it would be most stressful for the cats, was very respectful in completing work, held great conversation, and did a wonderful job as proven by before and after photos. Would certainly recommend."

"Great !! One service tech gave me phone assistance on Memorial Day. Then a second tech came out the next day to fully diagnose the problems and started the A/C again, in a temporary mode. He and the salesman (on the phone) then gave us a quote for all of the work and equipment. Later that week two more techs came and installed a new Carrier 2.5 Ton system. They were all very knowledgeable and professional. The total cost of the diagnostic work, the new system and the installation was very competitive. We were very pleased with RA Heating & Air Conditioning Inc. They are a quality company."

Trane Comfort Specialist. We have been in business since 1974 and offer 24/7/365 emergency service on all makes and models of HVAC equipment. We have Financing Available to qualified applicants. Award winning.

"We've used RG multiple times and have had nothing but the best service possible. Professional, courteous, knowledgeable, and the pricing is all exceptional. Most visits have been diagnosed and repaired in under 30 minutes. Our most recent event was when our A/C went out (19-yo house) on a Sunday morning. I scheduled service online and received a text within minutes that they had emergency openings if needed. I texted back that we could wait until Monday morning, and they were here at 8 am. As soon as the tech opened the A/C panel, he knew it was the capacitor. Replaced in about 5 minutes, and he stayed about another 15 minutes to make sure things were cooling. The job was completed, paid for, and he was gone by 8:30."

Heating and Air Conditioning questions, answered by experts

You should service your AC at least once per year, in the spring, and twice per year if your unit is 10 years or older. As your unit ages, more maintenance can catch problems early and help the system reach its full lifespan potential, usually 15 years.

Get on your HVAC technician’s schedule in early spring so your unit is ready to go for the season. If you’re doing two inspections per year, aim for one in the spring and one in the fall. You should also service your furnace once per year in the fall.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.
