HVAC in Charlotte is a long wet cooling season on two-story houses, with a heat system that sleeps until ice week. Attic handlers over Ballantyne and Huntersville ranches, and over older bungalows, clog condensate lines and stain ceilings that everyone calls a roof leak. Pollen packs filters. West sun on a tall facade cooks the upstairs while the thermostat downstairs looks fine. Lake humidity does not help. This city is not the High Country and not the ocean. The equipment is here to dry the air and survive hail season outdoors.
When the cool air quits, say if the outdoor unit is silent, cycling, or frozen over at the lines. A crushed return or a missing upstairs return can imitate a dead compressor in these two-story plans. Ask what gets ruled out. If heat will not run on the cold snap, say so, and say if you smell burning or gas. That week is when ignored furnaces and heat strips announce themselves. Skip the daisy chain of portable heaters as a strategy. Hail can also bend the outdoor fins. Mention it if the yard is full of granules.
A new system should be sized for this floor plan, not copied from the old tag. Leaky ducts in the attic are common in both the older neighborhoods and the big subdivisions. Ask if they will be sealed. Upper-floor misery is often airflow. Specify indoor and outdoor sections together. A new outdoor unit on an old coil should be described as its own compromise. Clammy rooms mean humidity was left out of the goal. That is a Charlotte summer failure even when the thermometer moved.
Ask about the pan, the float switch, and the drain line that clogs in July. Many so-called roof leaks in this city are that pan. On a maintenance visit, ask for a list, including the filter size and the outdoor unit after hail. Houses facing Norman or Wylie may see more wind-driven rain into a tired cabinet. Sheltered lots can skip the lake speech. If the bungalow never had a real return upstairs, say the comfort complaint is old.
Say cool or heat, dead or weak, and say Charlotte. HVAC here is upstairs heat, attic water, and a short rude winter. Call the number on this page.
