What Is Furnace Installation?

A furnace installation means replacing your old heating system with a new, more efficient gas furnace. This includes removing the old unit, installing the new furnace, connecting to existing ductwork and gas lines, testing the system, and ensuring it meets current code and safety standards.

When to call EVS:

Your furnace is more than 15-20 years old
Heating bills keep going up despite no change in usage
Your furnace needs frequent repairs
You hear unusual noises or inconsistent heating
You want to upgrade from an old unit to a high-efficiency model (90%+ AFUE)
You're buying a home with an unknown or aging furnace

Frequently Asked Questions

How long does furnace installation take?

Most residential furnace replacements are completed in one day. Complex installations (venting modifications, gas line upgrades, ductwork changes) may take 1-2 days.

Should I replace my furnace or repair it?

A good rule of thumb: if the repair costs more than half the price of a new furnace, or if your furnace is over 15 years old, replacement is usually the better investment. EVS can give you a straight answer — we do both repair and replacement.

What AFUE rating should I get?

AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts gas to heat. For Bay Area homes, 80% AFUE is the minimum. 90-96% AFUE is common for replacements. Higher efficiency means lower gas bills but higher upfront cost.

Does EVS install gas furnaces during a power outage?

We install furnaces year-round. Since gas furnaces don't require electricity to produce heat (just to run the blower fan), they remain a popular choice for Bay Area homes concerned about PG&E power shutoffs. A backup battery or generator can keep the blower running during an outage.

Do I need a permit for furnace replacement in Santa Clara?

Yes. Santa Clara, San Jose, Sunnyvale, and all Bay Area cities require permits for furnace replacement. EVS handles this — we pull the permit, schedule the inspection, and ensure the installation meets current code.

How long does a new gas furnace last?

A properly installed and maintained gas furnace typically lasts 15-20 years. High-efficiency models with variable-speed blowers may last longer. Regular maintenance (annual tune-ups) extends lifespan.

Can EVS install a furnace and AC at the same time?

Yes. If you need both, a combined installation saves on labor and coordination. We can quote the package as one job.

What brands of gas furnaces does EVS install?

EVS Mechanical installs Carrier, Bryant, Goodman, Daikin, and Lennox gas furnaces. We'll recommend the brand that fits your budget and efficiency goals.

Does EVS service the furnaces they install?

Yes. We provide ongoing maintenance and repair for every furnace we install. Local service team — not a warranty call center.

How does a gas furnace work?

A gas furnace burns natural gas in a combustion chamber, creating heat. The heat exchanger transfers this heat to air without mixing combustion gases with your home's air. The blower fan pushes the warmed air through your ductwork to each room. Exhaust gases vent outside through a flue pipe. Modern furnaces use electronic ignition (no pilot light) and modulating burners for efficiency.

Does a gas furnace work without electricity?

No — while gas provides the heat, your furnace needs electricity to run the blower fan, ignition system, and thermostat. During a PG&E power shutoff, the furnace won't operate unless you have a backup generator or battery system. The blower fan is the main power draw — a portable generator (2000-3000 watts) can keep most furnaces running.

How to repair a gas furnace vs. when to replace it?

Repair if: the furnace is under 10 years old, it's a single component (thermostat, flame sensor, blower motor), and repair cost is under $800. Replace if: the furnace is 15+ years old, the heat exchanger is cracked (safety issue), you need frequent repairs, or repair cost exceeds 50% of replacement. EVS gives honest repair-vs-replace advice.

What is a central heating system?

A central heating system heats your entire home from one location (furnace, boiler, or heat pump) and distributes warm air or water through ductwork or pipes. Most Bay Area homes use forced-air central heating — a gas furnace heats air that's pushed through ducts to each room. It's called "central" because one unit serves the whole house.

How do I find furnace repair services in Santa Clara?

Look for California C-20 HVAC contractors with local addresses (not call centers), verified reviews, upfront pricing, and fast response times. Check cslb.ca.gov to verify licenses. Ask about diagnostic fees, warranty on repairs, and if they stock parts locally. EVS offers 1-2 hour callbacks and honest repair-vs-replace guidance.

What are the benefits of changing your old furnace today?

Modern furnaces are 90-96% efficient vs. 60-70% for units from the 1990s. You'll see lower gas bills (20-30% savings), quieter operation, better temperature control, improved safety (no pilot light, sealed combustion), and eligibility for Bay Area energy rebates. Plus, you avoid emergency breakdowns during cold snaps.
