Four causes behind most hot and cold spots.
Airflow
Long runs, kinks, closed doors and missing returns leave rooms starved or stuffy.
Attic and roof
Upstairs rooms under hot or poorly insulated attics gain heat all afternoon.
Windows and sun
West-facing glass can turn one room into an oven at five o'clock.
Duct leaks
Air lost in the attic or crawl space never reaches the rooms at the end of the line.

Why are some rooms too hot or too cold?
The usual causes are duct leaks, long or undersized runs, missing return air, a hot attic and sun on big windows. A technician can measure airflow and pressure to find the cause. Our Comfort Map shows how these issues change the rooms in a house.
Should I repair or replace my system?
A repair makes sense when the system is in its middle years and the fix is small compared with a new one. A big repair on an old or failing system is usually money better spent on replacement. We show you both options in writing, and our Life Clock shows where your equipment sits in its typical life.
What size system does my house need?
Size depends on far more than square footage: insulation, windows, sun, ducts and how people use the house. An oversized system cools fast, shuts off early and leaves the air humid. We calculate the load instead of copying the old unit, and our Tonnage Finder gives you a starting range.
