Heating & air conditioning in Sherman, TX

Your local team in Sherman

Sherman sits at the top of the US-75 corridor, about an hour north of our Lewisville headquarters, and it's one of the fastest-changing cities we serve. The semiconductor boom on the north side has brought a wave of brand-new subdivisions, but most of Sherman's housing tells an older story: early-1900s homes around the Grayson County Courthouse square and Austin College, and mid-century ranch houses spread across the neighborhoods inside the FM 1417 loop.

Older Sherman homes commonly need their retrofit air conditioning reworked rather than simply replaced — returns that were never sized correctly, duct run through unconditioned space, and equipment decades past its prime. Newer builds out toward Sherman Town Center and US-82 need warranty-smart service and honest maintenance. Graco Heating & Air covers all of it — diagnosis, duct work, and replacement — with flat-rate pricing, a 2-year labor warranty on installs, and 24/7 emergency response to Sherman.

What Sherman's climate does to your home

Sherman summers regularly run past 100 degrees for weeks, so air conditioners work near their limits from June through September. Blue-northers can drop temperatures 30-plus degrees in hours, shocking heating systems awake, and spring brings hail and severe storms that damage condensers and knock out power. Grayson County's expansive clay soil swells and shrinks with moisture, and houses that move with it tend to pull their duct joints apart. Occasional ice storms round out a climate that punishes heating and cooling equipment from both directions.
