HVAC Company in Los Altos, CA

Furnace replacement in Los Altos is usually a retrofit problem before it’s an equipment problem. Most of this city was built between the 1940s and 1960s, so the houses were designed around a wall or floor furnace with no ductwork sized for modern forced-air equipment. Add warm, dry summers and cold winter mornings and you get a two-season demand load inside a house that never planned for it. We install, repair, and replace furnace and AC systems from nine major brands, and we work with your schedule through fast dispatch from 7am to 7pm. Call (855) 473-9061.

Why Los Altos Homes Are Different

The dominant housing stock in Los Altos is the mid-century California ranch: single-story, wood-frame, usually with a detached garage and a wall or floor furnace that has outlived its design life. Where central air was added, the ductwork is typically original 1960s sheet metal running through the crawlspace, undersized by modern standards and prone to leakage at the joints. Those old connections deserve a careful look before anyone starts cutting into them.

The climate shapes sizing as much as the housing does. Afternoon heat gain through west-facing ranch windows and a shallow attic is the main cooling load driver, while winter mornings still get cold enough that heat output matters. And in downtown-adjacent neighborhoods like Old Los Altos, heritage trees and tight side setbacks often make line set routing and condensing-unit placement the hardest part of the job. We handle installation, repair, and full replacement, so the same conversation covers both halves of the system.

Our Main Los Altos Services

Two jobs come up most often when Los Altos homeowners call us: getting cooling into a house that was built without it, and keeping an aging furnace running safely through the cold months.

AC Installation in Los Altos

Installing central air in a Los Altos ranch house usually starts with a load calculation, because the shallow attic and west-facing glass drive the sizing more than square footage does. In many homes the answer is a ducted system tied into new or upgraded ductwork; in others, the lack of a cavity for ducts pushes the conversation toward a ductless approach. Either way, equipment selection follows the home’s actual load and your budget, not what happens to be sitting in a warehouse. We’re certified to install Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. For the full scope, see AC Installation in Los Altos.

Furnace Repair in Los Altos

An old wall or floor furnace in a Los Altos home tends to fail in predictable ways: a pilot that won’t stay lit, a blower that runs but never warms the room, or a heat exchanger that has quietly aged out. Because we also work on the cooling side, our technicians catch cross-system issues that a heating-only contractor can miss, particularly where original 1960s ductwork is leaking conditioned air into a crawlspace. We service Rheem, York, Daikin, Bryant and the rest of our nine brands. Details are on Furnace Repair in Los Altos. Typical furnace repairs here run $175 – $825, and the written estimate sets the final price.

Furnace Replacement in Los Altos

Furnace replacement in Los Altos is a sizing and routing decision as much as an equipment swap. In a 1950s or 1960s ranch house the old wall or floor furnace rarely has a duct system behind it that meets modern standards, so a straight like-for-like replacement can leave the new unit fighting undersized, leaky sheet metal in the crawlspace. We treat Furnace Replacement as a full project: measure the actual load, inspect the existing distribution, and then recommend the right system for your home from nine major brands rather than the one brand we happen to carry. Our technicians have up to 8 years of experience across both heating and cooling equipment.

Wall and Floor Furnace Changeout

Signs you need it

A wall or floor furnace that’s been in the same spot since the house was built, with visible rust, a cracked heat exchanger, or a repair estimate climbing toward the cost of new equipment.

What it costs in Los Altos

A full furnace replacement in Los Altos typically falls in the $4,130 – $8,850 range depending on equipment and any ductwork the job requires, and the written estimate sets the final price.

How we do it

We calculate the home’s heat load, check the existing duct opening and clearances, pull the old unit, and set and commission the new furnace with the venting and connections brought up to current standards.

Forced-Air System Retrofit

Signs you need it

A ranch house that still heats from one wall furnace and has no central distribution at all, especially where the family has added cooling and now wants heat and air to share the same system.

What it costs in Los Altos

Retrofit work sits at the upper end of the $4,130 – $8,850 replacement range once new duct runs and routing are part of the job, and the written estimate sets the final price.

How we do it

We run a load calculation first, then plan duct routing through the crawlspace and attic around the house’s constraints, install the furnace and distribution, and test airflow room by room before we call it finished.

What Furnace Replacement Costs in Los Altos

These are typical estimated ranges for Los Altos, not a quote. The written estimate you receive after we see the house is the price that applies.

Can you replace my furnace with the same brand that’s already there?

Usually yes. We’re certified on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so if your existing unit is one of those, brand-matching isn’t a problem. If another brand makes more sense for your home’s load, we’ll say so. Call (855) 473-9061 for a free estimate.

Do I need new ductwork when I replace my furnace in Los Altos?

Not always, but it’s the first thing we check. Original 1960s sheet metal in a crawlspace is often undersized and leaking, and putting a new furnace on top of it wastes capacity. We’ll show you what we find and price both paths. Call (855) 473-9061.
