"PIC really offers the sort of trades service we used ro find in Wisconsin communities. Scott explained different options with newer technologies before letting me decide what was right for us and our pocket book. We've had him do both AC repair work and installation and we're planning a garage heating system this fall as well. Fast, knowledgeable, and respectful of our circumstances. I highly recommend PIC for any HVAC need, large or small. I've talked to many others who have had the same experience with them as well!"

Heating and Air Conditioning questions, answered by experts

Your air conditioner can temporarily run with a dirty filter, but it won’t work as efficiently. It will need to work harder to blow cool air throughout the room or house, and this can eventually cause the air conditioner to overheat or die prematurely. It’s much more cost-effective to clean or replace filters than to pay higher utility bills each month and replace the entire AC unit more often.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.
