Heating Installation
Planning a new furnace or heat pump for an Orange County home starts with the house—not a same-size equipment swap. Hana Hou Home evaluates the heating and cooling load, accessible ductwork, airflow, controls, electrical or gas connections, and installation requirements before providing a written proposal. If you are still comparing options, review heating repair, explore all heating services, or see how annual heating maintenance supports new equipment.
The right size system, installed correctly, is the difference between a house that heats evenly and one with a cold back bedroom every winter.
Once we’ve sized the system, we walk you through equipment options, gas furnace or heat pump, standard or variable-speed, and get a firm number in writing before anyone touches a wrench. Installation day usually runs a full day for a straightforward swap, longer if we’re modifying ductwork, adding venting, or relocating equipment. A good installation means the gas line or electrical connections are verified to code, the venting is correctly sized and sealed, and a startup check confirms the system is actually producing the temperature rise it should. A bad one is equipment that’s connected and left running without anyone confirming those numbers.
When It's Time to Replace Instead of Repair
If any of this sounds like your system, a new install is probably the better math than another repair bill.
- The heat exchanger is cracked, which is a safety issue rather than a repairable one
- You’ve called for repairs two or more times in the past 12 months
- Energy bills have crept up even though you haven’t changed your thermostat habits
- The system is 15 or more years old and the compressor or blower is starting to sound labored
- You’re finishing an attic room, ADU, or addition the current system wasn’t sized for
- You’re considering a heat pump to handle both heating and cooling from one system
If you’re on the fence, we’ll give you an honest read on repair-versus-replace costs before recommending anything. Sometimes the right answer really is one more repair.
A properly sized, correctly installed heating system is one of the few home upgrades that pays you back in lower bills, fewer repair calls, and a system that lasts the 15 to 20 years it’s supposed to. Cutting corners on installation shows up later as a comfort problem, or worse, a safety one, that’s harder to trace back to day one. If you’re comparing a repair against a full new installation, our heating repair team can give you an honest read before you decide.
Why Choose Hana Hou Home
Accurate Load Calculations
We size every system to your actual home, not a same-as-last-time swap.
Licensed Gas & Electrical Connections Verified to Code
Gas lines, venting, and electrical hookups are checked and inspected, not just connected.
30-Day Encore Promise on Every Install

Gas Furnace Installation
Sized to Your Home, Not a Same-Size Swap
A load calculation based on square footage, insulation, and existing ductwork decides the right furnace size, not just matching the old one. See our full heating services overview for everything we cover.
Heat Pump Installation
One System for Heating and Cooling
A heat pump handles both sides of comfort from one system, which is worth considering when you’re replacing an aging furnace and AC at the same time. See our AC installation page for how we size a heat pump for the cooling side too.
Ductwork Evaluation & Sizing
New Equipment Only Performs as Well as the Ducts It Runs Through
We test static pressure on existing ductwork before finalizing any equipment quote, since undersized or leaky ducts can undercut even the best furnace or heat pump.
Frequently Asked Questions
How do I prepare for a heating-installation estimate?
Gather recent utility bills, equipment and thermostat model numbers, repair records, comfort complaints, remodeling plans, and any rooms that run hot or cold. Make the indoor unit, outdoor unit, electrical panel, thermostat, and accessible ductwork available. Check current offers on the coupons page, then request a written, comparable scope.
What warranty coverage comes with a new heating system?
Separate the manufacturer’s parts warranty, any equipment-registration deadline, the contractor’s labor warranty, and Hana Hou Home’s Encore Promise. They may cover different problems for different periods. Get all terms, exclusions, transfer rules, maintenance conditions, and claim procedures in writing before approving the installation.
When is replacement better than another heating repair?
Replacement may be reasonable when a verified safety problem cannot be corrected economically, a major part fails on equipment in poor overall condition, repair history is increasing, comfort remains inadequate, or planned remodeling changes the load. Compare a documented repair diagnosis with an itemized replacement proposal; do not use age alone.
What installation and startup tests should be documented?
Documentation should match the equipment and may include electrical readings, gas pressure and combustion or venting checks, temperature rise, airflow and static pressure, refrigerant charge for a heat pump, thermostat operation, condensate drainage, safety controls, and model and serial numbers. Ask for manuals, warranty registration details, and startup results at handoff.
Does a heating replacement require a permit?
Requirements are set by the city or other authority having jurisdiction and vary with the project. Full system replacements commonly require permits and inspections. The proposal should name the responsible permitting authority, who obtains the permit, included fees, required testing, and who schedules the final inspection.
How long does furnace or heat-pump installation take?
A straightforward replacement may be completed in a day, but conversions, ductwork, electrical upgrades, gas or venting changes, difficult access, permits, or corrections can extend the schedule. Ask for a project-specific timeline, inspection plan, shutdown period, cleanup expectations, and what could cause delays before work starts.stall, we come back and fix it at no charge. Manufacturer warranties on parts apply beyond that window depending on the equipment you chose.
How is a new heating installation different from a heating repair?
Only testing and inspection can answer that. The contractor should evaluate accessible duct condition, leakage, return and supply capacity, filter arrangement, static pressure, and room airflow. Needed duct repairs or resizing should appear in the written proposal. Review related options on the heating-services page.
Should I install a heat pump or a gas furnace in Orange County?
A heat pump provides heating and cooling from one system; a furnace supplies combustion heat. The right choice depends on the home’s load, ductwork, electrical service, existing fuel and equipment, installed cost, energy rates, emissions preferences, and comfort goals. Compare modeled operating costs and complete scopes—not broad claims that one technology is always cheaper or better.
How should a new furnace or heat pump be sized?
A contractor should calculate the home’s heating and cooling loads rather than automatically matching the old unit or relying only on square footage. The evaluation should account for insulation, windows, orientation, infiltration, rooms served, and duct capacity. ENERGY STAR’s installation checklist recommends a Manual J or equivalent calculation.
How much does heating installation cost in Orange County?
Cost depends on the equipment type and efficiency, heating capacity, duct condition, electrical or gas work, access, permits, controls, and warranty. A useful quote should itemize equipment, labor, permit responsibility, duct or electrical changes, startup testing, and exclusions.
