An outdoor unit encased in ice, auxiliary heat that never shuts off, lukewarm air in both seasons — heat pump problems have their own signatures, and reading them right is the whole repair.
We work out of North Aurora, about 27 minutes from our North Aurora shop, and we handle heat pump calls across Wheaton and the rest of DuPage County.
You get the actual fault, in plain English, with a price before any work starts — and an honest read on whether repair still makes sense for the system's age.
Call 630-486-0401 if your Wheaton heat pump is showing any of these:
Here is how a heat pump repair call runs in Wheaton:
We test the system the way a heat pump actually works — heating, cooling, and defrost — with pressures, temperatures, and electrical readings in each. Reversing valves, defrost sensors, and auxiliary staging get checked specifically, because those are the failures generic AC diagnostics walk right past. No shortcuts on that step — not in Wheaton, not anywhere.
You see what failed, what likely caused it, and what the fix costs — before any work starts. If the system's age makes a major repair questionable, you get the repair-versus-replace math honestly, with the decision left where it belongs: with you. Ask any Wheaton customer who has watched us work.
The fix goes in right — correct parts, correct refrigerant handling, correct control configuration — and then the system proves itself through full cycles in both modes while we verify capacity and operation.
Heat pump components rarely die alone; something usually worked them to death. Before we leave, we check airflow, coil condition, charge, and the auxiliary heat settings, so the repair lasts instead of repeating.
A common DuPage County story: a heat pump limping along on auxiliary heat for months, with the electric bill quietly paying for a failure nobody diagnosed. If your winter bills jumped, that is worth a look before another billing cycle goes by.
Heat pump mistakes Wheaton owners make:
The money side, both seasons of it:
Age math runs faster on heat pumps: year-round duty means a 12-year-old unit has worked like a much older AC, so major component quotes — compressor, reversing valve — on older units get the honest repair-versus-replace treatment automatically. Both totals, side by side, with financing options on the replacement column; the decision stays yours. That policy has never once changed for a Wheaton customer, and it will not start now.
Real customers, real Google reviews
“Jojo and his team did an after-hours service call in a lightning fast manner. They were professional and at a very reasonable price. I highly recommend them to all the people I know.”
“The Apex Climate Control technicians are simply the BEST!”
Good to know
Usually the reversing valve or its solenoid — the component that flips the refrigerant direction and makes a heat pump a heat pump. Sometimes it is a control or thermostat issue instead, which is cheaper. Diagnosis tells us which; both are routine repairs for us.
First, the reassurance: heat pump supply air is naturally milder than furnace air — around body temperature — so it can feel cool even when it is heating fine. Genuinely cool air, though, points to low refrigerant, a failed reversing valve, or the system running in the wrong mode. If the house is losing ground against the thermostat, it is a real problem and worth a call.
It is the setting that runs backup heat alone, bypassing the heat pump. Use it when the heat pump has clearly failed — iced solid, making bad noises, tripping breakers — to stay warm until service. It is expensive to run, so it is a bridge to a repair, not a lifestyle. That has held true on every Wheaton job we have run.
Same honest math as any equipment, adjusted for the fact that heat pumps age in dog years — year-round duty means a 12-year-old heat pump has worked like a 20-year-old AC. Small electrical repairs: fix at nearly any age. Compressor or reversing-valve money on an older unit: you deserve both totals side by side, and you will get them.
Light frost that clears during defrost cycles is completely normal. A unit encased in thick ice that never clears is not — that means a defrost fault, low charge, or an airflow problem, and running it that way strains the compressor. Shut it to emergency heat and call us.
Yes — the major brands and the common failure parts (dual-run capacitors, contactors, defrost controls, fan motors) are familiar territory, and the truck is stocked for them. Who installed it does not matter to us; its condition does.
Ideally twice a year — once before heating season, once before cooling — because it works both. Annual service is the practical minimum. Year-round duty means maintenance matters more for heat pumps than for any other residential HVAC equipment. If you are in Wheaton, we can usually get eyes on it quickly.
