Packaged systems live outdoors in full Arizona sun, which shortens everything. Call for service if:
Weak airflow or warm air from the vents
Visible rust, corrosion or damaged cabinet panels
Burning smell or no ignition when heating is called
Water staining on the ceiling beneath the unit
The unit is 12-15+ years old and repairs are stacking up
Rising energy bills with no change in usage

Packaged AC, heat pump and gas pack repair
Heat exchanger inspection and combustion testing
Compressor, capacitor and blower motor service
Refrigerant leak detection and charge correction
Rooftop curb, duct and seal repair
Full package unit replacement and crane set
Rooftop work combines gas, high-voltage electrical, refrigerant and height. Here is why professional service is essential:
Gas packs require heat exchanger inspection. A cracked exchanger sends combustion gases into your supply air, which is the main carbon monoxide risk in a gas furnace or gas pack.
Failed curb seals let conditioned air escape and monsoon rain into your ceiling. We inspect the connection, not just the equipment.
Arizona heat punishes an undercharged system. Proper charge is measured, not guessed.
EPA Section 608 certification is legally required to handle refrigerant. Our technicians hold it.
Rooftop service demands proper fall protection and equipment. It is not a homeowner job.
We assess the unit’s age, condition and repair history and give you an honest repair-versus-replace recommendation.
You receive a flat diagnostic fee and a written repair quote before any work begins.
Our technicians complete the repair on the roof, testing combustion, electrical and refrigerant as applicable.
We verify temperature split, static pressure, gas pressure and safety controls before signing off.
We explain what failed, what to watch for, and whether the unit is close enough to end of life to plan for replacement.
Rooftop systems fail in the worst month of the year. Trust APES for package unit repair in Phoenix AZ, with honest repair-or-replace advice and pricing agreed upfront. We handle emergency HVAC repair Phoenix-wide, seven days a week.
Packaged units need more attention than split systems because everything is exposed:
Dust load is higher in Phoenix and a restricted filter is the most common cause of failure.
Maintain clearance around the unit so it can reject heat properly.
Dust and monsoon debris insulate the coil and raise operating pressures.
Deteriorated sealant is how water gets into the ceiling. It belongs on any Arizona monsoon season HVAC checklist.
Cabinet corrosion around the base panel signals a drainage problem worth addressing early.
Gas pack heat exchangers must be inspected before the first cold night.
Packaged systems benefit most from twice-yearly professional maintenance plan visits.

A package unit houses the compressor, coil, blower and heating section in one outdoor cabinet, usually on the roof. Split systems divide those components between an outdoor condenser and an indoor air handler.
A gas pack is a package unit that combines electric air conditioning with a gas furnace section in the same cabinet. It is common on Arizona homes without indoor mechanical space.
Typically 12-15 years. Constant sun exposure and monsoon debris shorten life compared with the same equipment in milder climates, which is also why AC units in Arizona generally last less time than the national average.
If the unit is over 12 years old and the repair approaches a third of replacement cost, replacement is usually the better value. We give you both numbers.
Yes. Our technicians are equipped for rooftop access and carry the fall protection required for safe service.
A brief dust burn-off smell at first heating of the season is normal. A persistent gas or burning odour is not shut it down, leave the house if you smell gas, and call.
Twice a year: cooling in spring, heating in autumn. The combustion side needs its own annual inspection.
Sometimes, but it requires indoor space for an air handler and new line sets and ductwork. We evaluate feasibility and cost during consultation.
