Largo sits in coastal Pinellas, where salt reaches the outdoor unit that also carries your heat. Sun Air Services repairs heating systems across Largo and the surrounding Pinellas communities.
Largo's position in coastal Pinellas produces the most aggressive equipment environment in our entire service area. Salt-laden air moves across the peninsula from both the Gulf and the bay, and it attacks outdoor HVAC equipment continuously. Homeowners here generally understand what that does to their air conditioning. The part that gets overlooked is that on a heat pump, the corroding outdoor unit is also the heater — so salt exposure quietly takes out your heating capability alongside your cooling, and you typically discover it in December rather than July.
If your Largo system cools fine but will not heat, corroded valve and defrost components are the first thing we check.
Healthy compressor, corroded heating parts — that is usually well worth fixing, and we will tell you when it is not.
Many Largo properties sit under association rules or building-wide contracts. We check that before scheduling work.
The components that make a heat pump heat rather than cool — the reversing valve and its solenoid, the defrost control board, and the sensors mounted on the outdoor coil — all live outdoors in that salt air. In coastal Largo we find them corroded well before the compressor itself has any real problem. The frustrating version of this is a system whose expensive parts are entirely sound but whose heating function has failed on relatively inexpensive corroded components. That is usually a very worthwhile repair, and it is the first thing we check on a Largo heat pump that cools well but will not heat.
Largo has an unusually varied housing stock — single-family homes, a large number of condominium and villa units, and a substantial share of properties built for seasonal residents. That variety produces heating setups we do not see as often elsewhere, including electric-resistance-only systems with no heat pump at all, and packaged units serving condo buildings under association control. If you are in a condo or villa, check whether your association or a building-wide contract governs the equipment before scheduling anything — it occasionally does, and it is better to know first.

(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.
We inspect the outdoor unit for salt corrosion on the reversing valve, solenoid, and defrost components — on a Largo heat pump that cools well but will not heat, that is nearly always where the fault is.
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 heating output and give you an honest assessment of corrosion elsewhere on the unit, because that determines whether this repair buys you years or months.
The signature coastal Largo failure. Corroded reversing valve or defrost components while the rest of the system is genuinely healthy.
Rust streaks, white powdery deposits, or crumbling fins mean the electrical components inside that cabinet are in a similar state.
Failed defrost control. The coil ices, the system cannot clear it, and heating output disappears at the worst moment.
Some Largo properties heat purely on electric resistance. That is not a fault, but it is expensive, and it is worth knowing that is what you own.
Defrost boards, sensors, and solenoids are affordable repairs, and on a Largo system with a healthy compressor they are frequently well worth making. Full reversing valve replacement costs more. We will tell you honestly how much corrosion we find elsewhere on the unit, because that affects whether the repair is a good investment. Call (813) 684-9919.

"Had Sun Air replace our entire system here in Largo last year. They recommended a coil coat treatment I hadn't heard of before — makes sense given how close we are to the water. System looks and works great a year later. Very impressed."
