Call came in from a homeowner on Knowles Drive reporting the system wasn't keeping up — running constantly but never hitting the set temperature. Tech pulled the filter, which was completely clogged, then found the evaporator coil partially iced over on a 2014 Carrier air handler. Refrigerant charge was also low, reading about 4 PSI under spec on the high side. Coil was allowed to thaw, system was recharged to manufacturer spec, and a new high-MERV filter was installed before leaving. Customer confirmed the house reached setpoint within a couple hours of the tech wrapping up.

We start every HVAC service call by checking the system's airflow and measuring temperature differentials at multiple points, which often takes 20-30 minutes before we even touch any components. The older ranch homes and colonials near Knowles Drive require extra attention to ductwork transitions and return air paths that weren't designed for modern efficiency standards. Our technicians spend the most time diagnosing these airflow issues because they're the root cause of most comfort complaints we see in this area.

Spring weather in Warwick means we're switching systems from heating mode to cooling preparation, which involves cleaning condensate drains, checking refrigerant levels, and testing electrical connections that may have loosened over the winter months. The established neighborhoods around Knowles Drive have mature landscaping that can interfere with outdoor unit airflow, so we always clear debris and trim back vegetation that's grown too close to equipment. Our master-level technicians know these older systems well and can spot potential problems before they become expensive repairs during summer's peak demand.

We've built our reputation over 16 years by maintaining the same installation and service standards that our grandfather established when he worked on the local school systems. Five of our seven technicians hold their own licenses, and both John and Joe personally inspect work to ensure it meets our family's standards rather than just industry minimums. Our escalation process means management stays directly involved when issues arise, which is why we've earned recognition from both Angie's List and the Better Business Bureau.
