Lakeland is the one part of our service area where gas furnaces are genuinely common and winters are genuinely cold. Sun Air Services repairs both gas and electric heat across Polk County.
Lakeland is the exception in this market, and it is worth saying so plainly. Sitting inland in Polk County, well away from the moderating influence of the Gulf and the bay, Lakeland genuinely gets cold — and unlike most of Tampa Bay, a real share of Lakeland homes heat with actual gas furnaces rather than heat pumps. That means when a Lakeland homeowner searches for furnace repair, they frequently do own a furnace, which is not true in most of the areas we serve. It also means the heating equipment here does substantially more work each winter than equipment forty miles west.
Lakeland genuinely has gas furnaces. We diagnose the ignition sequence properly instead of treating every heater as a heat pump.
We test for CO on every gas furnace call as standard, not only when a customer thinks to ask for it.
Flame sensors and igniters account for a large share of Lakeland furnace calls, and both are among our cheapest repairs.
A gas furnace fails differently from a heat pump, and the sequence is what tells you where the problem is. The system calls for heat, the inducer motor starts, the pressure switch confirms draft, the igniter glows, gas opens, and the flame sensor confirms ignition. Any one of those steps failing stops the whole sequence, and the most common culprits by a wide margin are a dirty flame sensor and a failing igniter — both inexpensive parts. Cracked heat exchangers are far rarer but genuinely serious, which is why we test for carbon monoxide on every gas furnace call rather than only when asked.
Lakeland runs all three. Established neighborhoods on natural gas mains commonly have gas furnaces. Newer construction and homes without gas service run heat pumps with electric backup. And a growing number of Lakeland homes use dual fuel — a heat pump that handles mild weather with a gas furnace taking over when it turns genuinely cold. Dual fuel makes more sense in Lakeland than anywhere else we serve, because Lakeland actually spends enough hours below the changeover temperature for the gas side to earn its keep.

(813) 684-9919 Schedule OnlineThis step gets skipped constantly and it matters. Most homes here do not own a furnace — they own a heat pump or an air handler with electric resistance heat. We confirm the equipment before diagnosing it, because the failure modes have almost nothing in common.
On a gas furnace we follow the ignition sequence step by step — inducer, pressure switch, igniter, gas valve, flame sensor — and find exactly where it stops. On a heat pump we check the defrost and reversing valve instead.
You get a firm written price before any repair begins. If the honest answer is that the equipment is not worth the repair, we will tell you that instead of selling you the part.
We verify temperature rise and, on any gas appliance, test for carbon monoxide and confirm the flue draws properly before we leave. That check is standard here, not an extra.
Almost always a dirty flame sensor or a failing igniter. Inexpensive, quick, and the most common gas furnace call we take in Lakeland.
The igniter is attempting to fire and not succeeding. Could be the igniter, the gas valve, or the pressure switch — the sequence tells us which.
Leave the house and call the gas utility first, then call us. Do not run the furnace again until it has been inspected. This is not a wait-and-see situation.
On a Lakeland dual-fuel system, a failed changeover control means one fuel is doing all the work — usually the expensive one.
Flame sensors and igniters are among the least expensive repairs we do, and they account for a large share of Lakeland furnace calls. Gas valves, inducer motors, and control boards cost more. Any suspected heat exchanger issue we assess on safety grounds first and cost second. Call (813) 684-9919 for a free phone estimate.

"Drive from Tampa to Lakeland doesn't deter Sun Air at all. They came out same week, repaired our heat pump, and did a full tune-up. Technician was fantastic — explained everything and didn't try to upsell us anything unnecessary. Great company."
