Homes in Union City: what pros run into
Many homes sit on slab foundations. Afternoon breezes off the Bay are common.
Alvarado was home to an early California sugar beet factory. Original ductwork in mid-century houses tends to leak at the joints. Sealing it can make a noticeable difference in comfort. Union City incorporated in 1959, joining Alvarado and Decoto.
Inland heat waves push older AC units past their limits, and wildfire smoke days make better filtration a common request. Most homes were built from the 1960s to the 1980s.
What to have ready
Check and replace the air filter before the visit, since a clogged one causes many problems on its own.

Common questions
Do you cover Dry Creek and Seven Hills?
Our network reaches Dry Creek, Decoto, Alvarado and Station District and the rest of Union City (94587). Tell us about a gate code, a tight driveway or a dog in the yard so the pro can plan. If nobody's available, we'll tell you.
Why does my system short cycle?
Turning on and off quickly can come from a dirty filter, a thermostat problem, low refrigerant or an oversized unit. It wastes energy and wears parts.
Should I repair or replace my system?
It depends on age, repair cost and how well it works. Ask for both options in writing, including efficiency and any rebates, and compare.
Any Union City details worth mentioning when I call?
Dry Creek Pioneer Regional Park is in the hills. The Hayward Fault runs along the base of the hills. The city sits between Hayward and Fremont. It helps to say roughly when your home was built.
Do I need my ducts cleaned?
Not on a fixed schedule. It can help after renovation dust, a pest problem or visible mold, but regular filter changes do most of the work.
