Just east of Raleigh, Knightdale has boomed with new neighborhoods around Knightdale Station and beyond, most of them filled with high-efficiency furnaces. Even these modern systems can falter when an eastern Wake County cold snap sets in.
Tech-On-Deck Heating, Air & Electric brings certified furnace repair to Knightdale with upfront flat-rate pricing and factory-trained, Trane Comfort Specialist technicians who know new equipment inside and out.
Even a newer furnace signals trouble before it fails. Keep an eye out for these in your Knightdale home.
Addressing any of these early prevents a minor fault from becoming a no-heat night.

Dirty flame sensors and control board faults follow close behind. These systems rely on sensitive electronics, so a single fouled sensor can keep the whole furnace from lighting.
Our certified technicians specialize in the modern systems common throughout Knightdale.
