"Our house is 60 years old. We have lived her 42 years, this the first time we have had the ducts cleaned. The air in the house just seems lighter, the biggest thing is we have a black glass top entertainment center in the den. U could clean and 2 days later it was dirty again. We had this done2 weeks ago, it just now needs cleaning. We are very happy with the results. Would highly recomd it. Also vent centers is a filter company with wonderful filters for your air ducts. Ventcenters.com we put them in all our registers"

"Excellent service.  Oscar and his crew go far and above what is necessary to fix or replace plumbing.  They are very conscientious, courteous and respectful.  They are also very considerate of your property, taking measures to insure that floors are kept clean and all debris is removed when they leave.  I will hire Rardin Plumbing and Heating again, and I highly recommend them.

"Almost immediately upon my request for service (via the website) I received a response, and I got excellent service from that point forward through completion of the project. Each individual I spoke with and met face-to-face was a professional and expressed their desire to expedite my order even during a time when it was very hot here, and I knew their workload was heavy. I'm extremely satisfied with the new A/C and expect to be happy with the new furnace when it gets cold here. Thanks for your diligence and an overall excellent job! David Cantrall"

Air Conditioning questions, answered by experts

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it.
