Q: What are the best air duct cleaning methods?

• <div><p>The best air duct cleaning methods involve removing the debris or dust in the ductwork through the use of a vacuum. Air duct pros refer to this method as negative pressure cleaning. To knock debris loose inside the ductwork, you may need to use a hand-operated brush or a rotary brush. You then can use the vacuum to suck up the loose debris and remove them from the ducts. If mold is present, pros may use a chemical spray to try to kill any bacteria or mold inside the system.</p></div>

Q: Why does my house smell like dog?

• <div><p>We love our pets, but a dog's fur, gums, teeth, and butt can all be sources of lingering smells that affect your home. If your dog is wet or dirty from playing outside, they can easily bring these scents into your house as well.</p></div>

Well, A/C is 10 years old, they did an inspection and evaluation. The capacitor was in need of replacement and was probably costing us in higher electric bills. Also they installed a programmable thermostat for us. We were very pleased.

Air Duct Cleaning questions, answered by experts

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation.

During your HVAC preseason maintenance call, your contractor will inspect the system for any problems and make small adjustments for better efficiency. Tasks include, though are not limited to:

Changing filters
Checking the thermostat
Clearing away dust and debris
Checking for mold
Inspecting electrical elements
Inspecting condensate lines and drain
Cleaning evaporator coils
Ensuring ignition function

While you can do some of these services yourself, hiring a professional to keep HVAC equipment running can be helpful. These experts know what to look for and may be able to spot potential issues before they become problems. Many HVAC companies offer annual maintenance plans.
