"We were Purl's customers for years for both our residence and business, including getting regular A/C and heater maintenance and replacing our units. In our home, they missed a leaking condensation line during the service that eventually led to water damage in two neighboring rooms (the water went into the walls and underneath the floors) and thousands of dollars in damage. In our business, they keep changing what is wrong with the unit and coming up with temporary fixes, all the while charging us more and more."

Heating and Air Conditioning questions, answered by experts

If you run an AC with a dirty filter, it could allow dust and dirt to build up in your ductwork, which could make you sick. At the same time, your air conditioner won’t work as efficiently as it would with a clean filter, likely resulting in less airflow, more wear and tear on your HVAC system, and higher energy bills.

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

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.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Mini-split air conditioners are less expensive to run than central air and are considerably more energy efficient. You can run the heating or cooling units in individual rooms and turn off the units in the rooms you aren’t using. This method allows you to save about 30% off your energy bill compared to a ducted system.
