Furnace Installation
FURNACE INSTALLATION IN PASADENA, CA
A federal efficiency rule finalized by the Department of Energy will require most new residential gas furnaces to reach 95 percent AFUE starting in late 2028, which means condensing furnaces, plastic vent piping, and a condensate drain are becoming the norm. Performance Plumbing, Heating & Air Conditioning, Inc. handles furnace installation in Pasadena, CA and across the San Gabriel Valley, sizing each furnace from your home's heat loss and completing gas, venting, and drain connections carefully. With 40+ years in heating, we explain every efficiency option and price installations upfront before any work begins. The old furnace is removed and hauled away, and the new one is tested before we leave.
FURNACES SHOULD FIT THE HOUSE, NOT THE BROCHURE.
A furnace that is too large heats in short, noisy bursts and wears itself out, while one that is too small runs constantly on the coldest nights. Both mistakes cost money every winter. We calculate your home's actual heat loss based on insulation, windows, and layout before recommending a furnace size or efficiency level.
Correct sizing, careful venting, and a clean gas connection are what make a new furnace quiet, safe, efficient, and long-lasting for years ahead. We handle each one with equal care.
- Heat-loss calculation for proper sizing
- Standard and high-efficiency furnace options

FURNACE INSTALLATION
DEPENDABLE WARMTH FOR PASADENA'S COOL SEASON.
Pasadena winters are mild by national standards, yet December and January nights regularly fall into the 40s, and older homes feel every degree. A new furnace should bring steady, quiet warmth without driving up gas bills. We help you choose between standard 80 percent models and high-efficiency condensing furnaces based on how long your heating season runs, where the furnace sits, and whether new vent routing is practical in your specific home.
CONDENSING UPGRADES CHANGE VENT ROUTES IN OLDER VALLEY HOMES.
Furnaces around the San Gabriel Valley are tucked into attics, hall closets, garages, and crawlspaces, and each location affects venting, combustion air, and service access. Converting to a condensing model may mean new vent routing and a drain path. We evaluate those details during the estimate, confirm clearances and gas line capacity, and plan an installation that fits your house cleanly instead of forcing equipment into a space.
VENTING IS WHERE WE REFUSE TO CUT CORNERS.
Most furnace problems we see from other installations trace back to venting: wrong pipe sizes, poor slope, missing supports, or terminations placed too close to windows. After 40+ years working with gas appliances, we treat venting as a safety system, not an afterthought. Every connection is secured, sloped, and inspected, and combustion is tested once the furnace runs. Ready to plan a safe, efficient furnace replacement for your home?
WHAT A WELL-INSTALLED FURNACE DELIVERS.
Lower Gas Bills
High-efficiency condensing furnaces convert far more fuel into heat, and correct sizing keeps runtimes efficient, so monthly gas bills drop noticeably throughout the heating season.
Quiet, Even Warmth
Modern multi-stage and variable-speed furnaces heat gradually, delivering consistent temperatures across rooms without the blasts of hot air and sudden shutoffs older units produce. Rooms feel calmer.
Safer Operation
Proper venting, secure gas connections, and verified combustion protect your household from the risks that come with aging heat exchangers and poorly installed exhaust piping.
Reliable Cold-Night Starts
A new furnace with fresh ignition components and a matched blower starts dependably, ending the anxiety of wondering whether the heat will come on during the next cold snap.
Better Airflow Throughout
Pairing the furnace blower with your ductwork and filter setup improves circulation, which helps both heating in winter and cooling in summer when the furnace blower moves conditioned air.
Future-Ready Equipment
Choosing a high-efficiency model today prepares your home for upcoming federal standards and positions it well if you later decide to add or upgrade central air conditioning.
our services
OUR FURNACE INSTALLATION WORK.
We install gas furnaces for homes throughout Pasadena and the San Gabriel Valley, handling every connection a safe installation requires, from the gas line and venting to ductwork, drains, and controls.
HIGH EFFICIENCY
Condensing Furnace Installation
Condensing furnaces capture extra heat from exhaust gases, reaching 90 percent AFUE or higher. We install the plastic vent piping, route the condensate drain properly, and configure the furnace for quiet, efficient operation.
STANDARD MODEL
80 Percent Furnace Installation
Where existing metal venting remains suitable and heating seasons are short, a standard-efficiency furnace can be a sensible choice. We confirm venting compatibility, clearances, and gas supply before installing it.
TIGHT SPACES
Attic and Closet Furnace Replacement
Replacing furnaces in attics, hall closets, and crawlspaces requires careful handling and precise fitting. We plan access, protect your home during removal, and position the new unit for easy future service.
GAS CONNECTION
Gas Line and Shutoff Installation
Every new furnace receives a properly sized gas connection with an accessible shutoff valve and sediment trap. We test the connection for leaks before lighting the burners for the first time.
EXHAUST PATH
Venting and Flue Installation
We install or modify vent systems to match the new furnace, maintaining correct pipe size, slope, support, and termination clearances so combustion gases leave your home safely every heating cycle.
MATCHED AIRFLOW
Plenum and Duct Connection
The new furnace must connect cleanly to supply and return ductwork. We fabricate or adjust transitions, seal connections, and verify airflow so warm air reaches every room without losses. Nothing is left unsealed.

FAQ
FREQUENTLY ASKED QUESTIONS.
Replacing a furnace involves decisions about efficiency, sizing, venting, and timing. These answers explain the key choices so you can plan a replacement that fits your home, comfort goals, and budget.
What Does AFUE Mean On A Furnace?
AFUE stands for annual fuel utilization efficiency, the percentage of fuel a furnace turns into usable heat. An 80 percent furnace loses about a fifth of its fuel through the vent, while condensing models reach 95 percent or higher.
Is A High-Efficiency Furnace Worth It In Southern California?
It depends on your heating hours and installation location. Mild winters shorten payback periods, but condensing furnaces also bring quieter operation and future compliance. We compare lifetime operating costs so you can decide whether the upgrade truly makes sense.
How Long Does A New Furnace Typically Last?
Gas furnaces commonly last 15 to 20 years when they receive regular maintenance. Proper sizing, clean filters, correct gas pressure, and good venting all extend that lifespan, while neglect and oversizing shorten it through overheating and constant short cycling.
Does A New Furnace Need Different Venting?
Sometimes. Condensing furnaces use plastic vent pipes and need a drain, while 80 percent models use metal flues. Switching types, or replacing a furnace connected to a shared water heater vent, may require venting changes for safe operation.
What Is The Difference Between Single-Stage And Two-Stage Furnaces?
Single-stage furnaces run at full output every time they turn on. Two-stage and variable-speed models run at lower output most of the time, delivering steadier temperatures, quieter operation, fewer drafts, and better efficiency during Pasadena's mild heating days.
How Long Does Furnace Installation Take?
Most straightforward furnace replacements are finished in 1 day. Projects involving venting changes, relocated equipment, new gas lines, or duct modifications may take a second day. We explain the timeline during the estimate so you can plan accordingly.

HOW WE WORK
FROM HEAT-LOSS MATH TO FIRST WARM NIGHT, HERE IS HOW.
STEP 01
WE INSPECT THE SPACE
We look at your current furnace, its location, venting, gas line, ductwork, and electrical supply. Those details determine which furnace types fit your home and whether any venting or piping changes are required.
STEP 02
WE CALCULATE HEAT LOSS
Using room measurements, insulation levels, and window details, we calculate how much heat your home actually needs. That figure guides furnace sizing and prevents the short cycling that oversized equipment causes. Guesswork has no place here.
STEP 03
WE COMPARE OPTIONS
You review standard and high-efficiency furnaces with upfront prices and expected operating costs. We explain what each upgrade delivers so the final choice matches your comfort priorities and budget comfortably. There is never any pressure to upgrade.
STEP 04
WE REMOVE THE OLD UNIT
Our team shuts off gas and power, disconnects the old furnace safely, and removes it from your home while protecting floors, walls, and belongings along the way. We haul the old equipment away for you.
STEP 05
WE INSTALL AND CONNECT
We set the new furnace, connect gas with a shutoff and sediment trap, install venting and condensate drainage, and attach ductwork transitions. Every connection is checked for leaks and security before startup. Neatness matters too.
STEP 06
WE TEST COMBUSTION
Finally, we light the furnace, measure gas pressure, check the flame and venting, verify temperature rise, and confirm all safety controls work. You receive a walkthrough of the thermostat, filter, and care schedule.
