Why is my AC running but not cooling?
Common causes include incorrect thermostat settings, a dirty filter, restricted airflow, drainage problems, or a refrigerant issue. Checking the thermostat and filter can rule out simple problems. A technician can diagnose the rest without guesswork.
Should I repair or replace my HVAC system?
Age alone does not make the decision. Repair history, current condition, comfort problems, operating costs, and the cost of the repair all matter. A diagnosis lets you compare the immediate repair with the longer-term value of replacement.
Why are some rooms hotter or colder than others?
Restricted registers, dirty filters, duct leakage, insulation, direct sunlight, or equipment sizing can all contribute. The pattern between rooms helps narrow down where the comfort problem begins.
How often should heating and cooling equipment be serviced?
ENERGY STAR recommends annual pre-season checkups, with cooling equipment checked in spring and heating equipment checked in fall. Filters should be checked monthly during heavy-use seasons and cleaned or replaced as needed.
What should I share when requesting an estimate?
Share the service address, the best phone number, what the system is doing, when the problem started, and any model information you can easily find. You do not need to diagnose the system yourself.
Does D&A work outside the three-county area?
Wayne, Duplin, and Sampson counties are D&A's primary service area, but work outside those counties may be considered. Call with the location and project details to ask.
