Heating System Installation
Bay Area's #1 Choice

Heating system installation covers sizing, permitting, and putting in a new furnace, heat pump – whether that’s a first heating system or a replacement for one that’s stopped keeping up. United HVAC, Plumbing & Electrical installs and matches equipment to the home across San Jose, Santa Clara, and Cupertino, rather than defaulting to whatever unit is easiest to sell.

What Is Professional Heating System Installation and What Does It Cover?

Sizing the equipment correctly, handling whatever electrical or venting work the job calls for, and pulling the required permit before anything goes in – that’s what heating systems installation actually means, done right. Skip the sizing step and that’s usually the difference between a system still running strong past year fifteen and one already struggling by year five.

Types of Heating Systems We Install

The right system depends on what’s already in the home and what the household actually needs:

• Central heating system installation – a gas furnace tied into existing ductwork, still the most common replacement for homes that already have a duct system in place.
• Ductless heating system installation – a variable-speed heat pump with no ductwork required, the practical fix for older San Jose and Santa Clara homes that were never built with ducts.
• Whole-home heat pump installation – a ducted heat pump tied into existing ductwork, an alternative to a gas furnace that performs well given how mild Bay Area winters typically run. 

Signs It’s Time to Replace Your Existing Heating System

A furnace that’s cycling more often without keeping the house as warm, or a sudden jump in the winter gas bill, both point to a system nearing the end of its service life. Rattling, a burning smell on startup, or a system that’s already had multiple repair calls in one season make replacement the more practical option. A heating system installation near me search is worth running once repair costs start approaching what a new system would cost outright.

Heating System Installation: How the Process Works

Every installation starts with sizing the equipment correctly, not quoting whatever unit happens to be on the truck. Most jobs on existing ductwork or venting finish in a day; ductless and radiant installs often move just as fast since there’s no duct work to tie into.

Load Calculation, System Selection, and Permitting

A Manual J load calculation determines the right output size for the home before any equipment gets ordered – undersizing a furnace or heat pump means it runs constantly and still can’t keep the house at temperature. California Title 24 sets minimum efficiency requirements for new heating installations, and the permit covers that compliance along with the inspection that follows. System selection happens at this stage too, weighing a gas furnace against a variable-speed heat pump based on the home’s ductwork and the household’s usage.

What Happens on Installation Day

A furnace install means gas or electrical lines get connected, the ductwork gets tied in, venting gets confirmed – then a full test cycle before anyone calls it done. Ductless heat pumps go differently: indoor units mounted zone by zone, refrigerant lines routed out to the condenser. Either way, nothing gets left running on a hope. Full output gets tested first.

Heating System Installation Cost in the Bay Area

$6,000 to $12,000 covers a gas furnace replacement where the ductwork’s already there. A ducted whole-home heat pump runs higher – $15,000 to $30,000. Ductless mini-splits and radiant floor systems land somewhere in between, depending on zone count and square footage.

Factors That Affect the Final Price

System size and efficiency rating drive most of the cost difference between a base furnace and a high-efficiency heat pump. Ductwork condition matters for central systems – usable existing ducts keep the job toward the lower end, while damaged or undersized ductwork adds labor and material cost. United normally installs Carrier or Bryant furnaces, Mitsubishi, Carrier, Cooper and Hunter heat pumps.
