HVAC Company in Cupertino, CA
Dalton Heating & Air handles heating and cooling work across Cupertino, from quick AC repairs in ranch-style homes off De Anza Boulevard to full heat pump installations in newer builds near the hills. Most Cupertino jobs fall into one of three buckets: an air conditioner that quit during a warm spell, an aging furnace making noise, or a homeowner ready to switch to a heat pump. Every job starts the same way: a written price before any work begins, a background-checked technician inside the scheduled window, and a full-year written guarantee on the repair. If you need us now, call (361) 306-9515 and a real person answers, any hour.
Why Cupertino Homes Are Different
Cupertino sits in a climate band where summer afternoons climb into the 80s and low 90s while winter nights dip near freezing. That swing means your AC and your furnace both earn their keep, and a system that limps through one season often fails hard in the next. The housing stock splits roughly into three groups: mid-century ranchers built between the 1950s and 1970s, larger two-story homes from the 1980s and 1990s, and a steady wave of modern builds and remodels. Each one changes the job. A 1960s rancher on a slab often has ductwork that was never sized for today’s high-efficiency equipment, while a 1990s two-story in the Monta Vista area may have separate zones that need load-matching. Hillside lots near Regnart Canyon run hotter in the afternoon and cooler at night than the valley floor, which shifts how we size equipment. Several Cupertino neighborhoods also sit within HOA boundaries or under Santa Clara County permit rules where equipment location, noise limits, and condenser placement are not suggestions – they are checked. We handle the paperwork so the homeowner does not have to chase it.
Our Main Cupertino Services
Cupertino homeowners call us most for cooling failures in summer and heating failures in winter, with heat pump installation closing the gap as more homes move toward electric. Each service has its own Cupertino page below.
AC Repair in Cupertino
When an air conditioner stops cooling in Cupertino, the usual suspects are capacitor failures, refrigerant leaks, contactor wear, and clogged condensate lines, but older homes add their own twist: aged ductwork and mismatched equipment from past repairs. Our technicians diagnose the fault, put the repair price in writing before touching a part, and stock common components on the truck so most fixes happen in one visit. If a repair fails within the guarantee period, we come back at no charge. Read the full breakdown at AC Repair in Cupertino.

Heat Pump Installation in Cupertino
Heat pumps work well in Cupertino because winter temperatures rarely dip far enough to blunt their efficiency, and they eliminate the gas furnace entirely. The key is correct sizing for the home’s heat loss and gain, not a rule-of-thumb swap, and that means a load calculation before any equipment gets ordered. We install heat pumps sized for the home, not the square footage, and provide a fixed written price and a set install date. See Heat Pump Installation in Cupertino for the full detail.

Furnace Repair in Cupertino
A furnace that fails on a cold Cupertino night is a safety issue, not just a comfort problem. Common failures include flame sensors, igniters, gas valves, and blower motors, and older furnaces in mid-century homes often show the first signs of a cracked heat exchanger. We respond fast to no-heat calls, put the repair in writing before starting, and stand behind the work for a full year. Details at Furnace Repair in Cupertino.

Pricing for HVAC Company in Cupertino, CA
| Service | Typical range in Cupertino |
|---|---|
| AC repair | $150 – $650 |
| Furnace repair | $150 – $700 |
| AC installation | $3,500 – $7,500 |
| Tune-up | $80 – $200 |
What moves a Cupertino job toward the top of those ranges is usually age: a 25-year-old furnace needs parts that are scarcer, and a 20-year-old AC may need multiple components replaced in the same visit. Regardless of the number, the price is put in writing before any work begins so the quote at the door is the price on the invoice, full stop.
