"Not only is David highly skilled in resolving HVAC issues, but he was a pleasure to work with and taught me a lot! He was punctual, communicative and patient, taking the time to explain what the issues were (in plain English), and in the end solved my A/C problems much faster AND cheaper than the so called “best in town” HVAC company I was working with. Highly recommend, and will be calling him back again!"

"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

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

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

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.
