"Provider was very professional and very knowledgeable in all aspects of energy efficiency. It seemed that the assessment was honest and professional with no pressure to pursue their product.  He checked the HVAC units, AC registers, attic insulation, exterior walk around and windows.  Provided some simple inexpensive improvements to improve energy.  Details were provided for research for the other more expensive options for energy efficiency and all were reasonably priced.

"Ben at clean air pro services was prompt, professional, and personable. He showed me a before and after of my ducts, then showed me what he retrieved from my ducts. You won’t believe the amount of dust and crud that we breathe in on a daily basis. We also tried them out for our dryer vent cleaning. Again another professional and quality job. I totally recommend this company."

Heating and Air Conditioning FAQs, answered by experts

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.
