AfterHVAC Company in Sunnyvale, CA
Meadowsweet Heating & Air is a Sunnyvale HVAC company built around a simple commitment: a written price before work starts, a background-checked crew in shoe covers, and a 365-Day Done Right Promise on every job. Sunnyvale’s housing stock makes our work different from most Bay Area cities. Thousands of 1950s and 1960s ranch homes here were built without any ductwork at all, only a floor furnace or wall heater. That means many Sunnyvale families aren’t replacing an old AC, they’re adding cooling to a house that never had it. Call (747) 966-3037 any hour and a live person answers, not a voicemail tree.
Why Sunnyvale Homes Are Different
Sunnyvale sits in a warm inland pocket of the South Bay, shielded from ocean air by the Santa Cruz Mountains. Summer heat events regularly hit 95 to 100 degrees, while winter lows rarely drop below 35. That asymmetry shapes every load calculation we run here. The bigger issue is what’s behind the walls. The dominant Sunnyvale home is a 1,000 to 1,600 square foot stucco ranch built between 1950 and 1975, slab-on-grade, with low or no attic clearance. Those homes were designed for mild summers. Many never got central forced air.
The practical result shows up constantly in east-side neighborhoods like Ponderosa and Borregas. A homeowner calls us for an AC repair or a quote, and we find the only heat source is an original 1960s floor furnace. No plenum, no ducts, no air handler. The entire system has to be engineered from scratch. Duct runs are tough on slab foundations with tight attics, which is why ductless mini-splits and high-velocity small-duct systems are often the right retrofit path here. That’s the Sunnyvale reality, and we plan for it on every visit.
Our Main Sunnyvale Services
The calls we get most in Sunnyvale split into two patterns: cooling systems failing during heat spikes, and heating systems that were never more than a floor furnace in the first place. Here’s how each plays out in this city.
AC Repair in Sunnyvale
Sunnyvale’s inland heat means AC failures don’t wait for convenient times. When a condenser gives out during a 98-degree stretch in a neighborhood like Raynor or Cherry Chase, the house heats up fast, especially for kids and pets. Our techs arrive with the right parts for the major brands, diagnose the problem, and write a clear price before touching anything. We explain what failed in plain language and what it costs to fix before the work begins. For the full picture on cooling repairs in Sunnyvale, see our AC Repair in Sunnyvale page, which covers pricing, common failures, and same-day response.
Furnace Repair in Sunnyvale
Sunnyvale winters are mild by national standards, but a failed furnace on a 38-degree January morning still makes the house uncomfortable in a hurry. Many of the furnaces we see are original equipment from the 1960s and 1970s, or floor furnaces that haven’t been opened in years. We carry parts locally for brands like Rheem, York, and Daikin, and our techs know the old east-side housing stock well. A written price comes before any work, every time. For details on common Sunnyvale furnace issues and repair costs, visit our Furnace Repair in Sunnyvale page.
AC Installation in Sunnyvale
This is the job that defines Sunnyvale. A large share of our installation work here is a first-time AC retrofit into a home with zero existing ductwork. Those slab-on-grade ranches with tight attics don’t fit a traditional ducted system easily, so we frequently size ductless mini-split systems or high-velocity small-duct options instead. Every installation starts with a load calculation for this specific house, not a rule-of-thumb guess. We handle permits, order the equipment, and set a firm install date with a fixed written price. Read more on our AC Installation in Sunnyvale page, including costs and what a retrofit actually involves.

Pricing for HVAC Company in Sunnyvale, CA
| Service | Typical range in Sunnyvale |
|---|---|
| AC repair | $150-$650 |
| Furnace repair | $150-$700 |
| AC installation | $3,500-$7,500 |
| Tune-up | $80-$200 |
What pushes a Sunnyvale job toward the top of those ranges is usually the house itself. Low attic clearance and slab construction make duct work slower, and a first-time retrofit costs more than a like-for-like swap. That’s exactly why we give every homeowner a written price before any work starts, so there are no surprises after the fact.

What Sunnyvale Customers Say
"Comfortable in every room now, and not a trace that a crew had been here. Booties, drop cloths, the works. They even wiped down the thermostat they'd handled. Really considerate."
- Lamar Finch"New system install. They protected the hallway floor all the way to the attic and vacuumed after. Worked quietly around my work calls. Not a trace left behind."
- Rosalind Okeke"AC repair in July. The tech laid a mat down by the indoor unit and wore booties through the house. Fixed it fast and left zero mess. Quiet and kind, good with our nervous dog too."
