Our AC quit on the first really hot day of the year. I called in the morning and Precision had someone out the same afternoon — found the problem fast and had us cool again before dinner. Honest people doing honest work, exactly what you want from a local HVAC company.

Our older home needed a full system replacement and we were nervous about it. The team walked us through the options in plain English, worked clean, and finished in a day. Best HVAC experience we've had in Sunnyvale by a mile.

Heat went out over a cold weekend and I expected to wait until Monday. Called Precision on a Sunday and they talked me through it on the phone, then had a tech out fast. Couldn't ask for better neighbors in this business.

Local roots

Trusted by Homeowners in Sunnyvale

We're an HVAC company built around Sunnyvale and the nearby areas — the same neighborhoods, the same hot inland summers and cooler, damp stretches. Comfort here depends on a system that's matched to the local climate and kept in good shape, whether that's an older home or a newer build.

That local knowledge matters. We know the homes around Sunnyvale Heights, North Sunnyvale, and South Sunnyvale, and we plan every job around what your system actually is — not a one-size-fits-all template.

What sets us apart

Our Name on Every System We Service in Sunnyvale

When our name is on the work, it's the same name people in Sunnyvale pass on to a neighbour. We started this company because the people we'd be working for are our neighbours — the kind of accountability you don't get from an out-of-town crew passing through after the first heat wave.

That's why we run small, why we show up when we say we will, and why the person who assesses your system is on the job watching the work get done. It's a slower way to build a business — and the only way we'd want to.

Common questions

HVAC FAQs

Quick answers to the questions Sunnyvale homeowners ask us most.

How do I know if my system needs repair or replacement?

If most of the system is sound and the issue is isolated, a repair is usually the right call. Widespread wear, an aging unit, or repeated breakdowns generally point toward replacement. Either way, we'll give you a straight read on what you're actually looking at — no pressure either way.

How quickly can you respond to HVAC issues?

We aim to respond quickly, especially for urgent no-cooling or no-heating calls. Because our team is based around Sunnyvale, drive times are short and same-day help is realistic for most of the area.

Do you service all HVAC brands?

Yes — we service and repair a wide range of heating and cooling systems, from older equipment to the latest high-efficiency units.

Do you handle emergency HVAC services?

Yes. If your system has stopped, is blowing warm air, or you've lost heat, call +1 408-705-2526 and we'll get someone out as quickly as we can.

How long does an AC or system replacement take?

Most residential installations are completed within a day, depending on the property and setup. Larger or more complex Sunnyvale homes can take a little longer, and we'll give you an honest timeline before we start.

Do you work throughout the Sunnyvale area?

Yes — we serve Sunnyvale and nearby areas including Sunnyvale Heights, Sunnyvale Park, North Sunnyvale, South Sunnyvale and more. We know the homes and the systems common to the area.

Are you actually a local team?

Yes. We're a family-run team with deep local roots based around Sunnyvale — the same people answer the phone, assess the work, and are on-site while it gets done. We're not a national outfit passing your job to whoever's free that week.
