Rooftop & Package Unit Repair for San Fernando Valley Homes
A lot of San Fernando Valley homes don’t have a furnace in the garage and an AC unit in the yard. Instead, everything is in one box, called a package unit, sitting on the roof or on a pad beside the house. Valley HVAC Network connects homeowners with independent, licensed local HVAC contractors who repair, service and replace residential rooftop and package units.
Types of Package Units
- Gas pack: air conditioning plus a gas furnace in one cabinet
- Package heat pump: one unit that both heats and cools with electricity
- Package AC with electric heat strips, common in some older homes and additions
Signs Your Package Unit Needs Service
- Warm air in summer or cool air in winter
- Water stains on the ceiling under or near the unit, often from a clogged condensate drain or a leak around the roof curb
- The unit runs nonstop or turns on and off every few minutes
- Loud humming, buzzing or rattling from the roof
- Rust, missing panels or bird nests visible on the cabinet
- Higher electric or gas bills with no change in how you use it
Rooftop Units Need Extra Care
Package units on the roof take the full Valley sun, dust and wind, so coils clog and panels loosen faster. Please don’t climb onto the roof to check yours. A licensed tech has the ladder, safety gear and know-how to work up there safely, and can spot problems with the ductwork connections and the curb the unit sits on.
Leak near the unit? Sometimes the water is coming from the AC’s drain, and sometimes from the roof flashing around the curb. If the roof is the problem, Valley Roofing Network can connect you with a licensed roofer.
Replacing a Package Unit
Replacing a rooftop unit is a bigger job than a split system. The new unit has to fit the existing curb or need an adapter, the ducts have to line up, and some jobs need a crane to lift the old unit off and the new one on. A licensed contractor handles the permit and can tell you whether a like-for-like package unit or a different system makes more sense for your home.
Common Questions
How often should a package unit be serviced?
Once a year is a good rule, and gas packs benefit from a check before heating season. See maintenance and tune-ups.
Do you handle commercial rooftop units?
Yes. For offices, shops and restaurants, see commercial HVAC.
