"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. I ended up having to create THREE different accounts because every time I went to place a new order, it would not let me login and it would not send a password reset email. DON'T GET RIPPED OFF."

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."

"Dale was very thorough in his examination of my situation and gave me clear explanations of what was going on. Other firms that quoted the work insisted that the entire basement needed to be done. Dale said that we only need to fix what is leaking. Cost to do that was one third that of other bids. Crew was on time, prompt and thorough. I would definitely use this firm again."

"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."

Additional DBAs - Action Electric of Dane County, Action Plumbing, Action Plumbing and Air, Action Plumbing Heating Air Conditioning & Electrical Co, Action Plumbing Heating Air & Electric. Award winning. See website for additional service areas.

"Great communication with the office staff. Both a plumber and electrician came out last week. Garrett was the electrician who installed 3 ceiling fans where there were no ceiling fans previously. I ordered the fans on-line and they came un-assembled. He had no problem figuring out how to assemble and install the fans. He made sure I was completely satisfied before he left. The plumber just had to cap off a gas stove that was no longer going to be used. When he turned the gas back on, he made sure the seal with tight and that my gas fireplace was still working properly. Could not be more pleased with the office staff and professionals who worked on my issues. Will definitely use them again."

Heating and Air Conditioning questions, answered by experts

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

Usually, ductwork is not included when you purchase a new HVAC system; it needs to be purchased separately. As far as installation, you’d need to speak with your local duct installer or HVAC technician directly to learn what their services include, but having your entire ductwork system replaced is likely to be more expensive than simply having your new AC unit installed without ductwork replacement.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

A new HVAC unit typically adds about $2,500 to $3,000 to the value of your home or about 5% to 7% of your home’s value. Since a new unit can cost up to or more than $10,000 to install, it’s up to you to decide if the upfront cost is worth the added value. Consult a local AC installer to determine next steps.

You can buy a new AC capacitor through most big-box home improvement stores, from an HVAC contractor, or from the manufacturer. Use the model number of your air conditioning unit to make sure you purchase the right part for your unit. Also, keep in mind that the cost of this type of part can vary significantly depending on who you purchase it from, so shop around to get the best price.
