Approving a new heating system installation is the easy part. What comes next (the timeline, the paperwork, the permit process, what your house will look and smell like afterward) is where most homeowners find themselves searching for answers. If you’re in Tulare or anywhere in the surrounding valley, this post walks you through the full process from first visit to first cycle, including the California-specific steps that most generic HVAC guides skip entirely.
At Central Heating and Cooling, we’ve been providing heating system installation and heater service in Tulare and across the Central Valley since 2018. Every project starts with a free estimate, and every homeowner we work with gets the same direct answers we’re about to give you here.
Step One: The Free Estimate & System Selection
Before any equipment is ordered, a technician visits your home to perform a load calculation. This isn’t a quick eyeball of your square footage. A proper load calculation, following the Manual J method required under California Title 24, accounts for insulation levels, window placement, ceiling height, duct condition, and how your home is oriented on the lot. The goal is to size the system for your actual house, not a house like yours.
Tulare County’s valley floor winters average around 44.7°F. That’s a damp, penetrating chill rather than severe cold. That climate profile matters for system selection. You don’t need the heating capacity a home in a colder northern climate would require, and oversizing a system here leads to short-cycling, where the unit runs in brief bursts rather than full heating cycles, reducing efficiency and shortening equipment life. The estimate visit is also when we compare your options: a gas furnace, a heat pump, or a ductless mini-split system. Each has tradeoffs in upfront cost, operating cost, and compatibility with your existing ductwork. We factor in your budget and efficiency goals before making a recommendation.
What Homeowners Should Do Before Installation Day
A little preparation on your end makes the installation go smoother and faster. None of it is complicated.
- Clear the work area. Provide at least three feet of clear access around the installation site, whether that’s your utility room, attic, or garage. Move stored items out of the path the crew will use to bring equipment in and out.
- Secure pets. Keep dogs, cats, and other animals in a separate room or away from the property for the day. Open doors and unfamiliar people are stressful for animals and can slow down the crew.
- Confirm the permit plan. Ask at the estimate stage whether your project requires a permit. In California, permits are required for virtually all HVAC replacements and new installations. A reputable contractor pulls the permits on your behalf. You shouldn’t have to handle this yourself. Confirm that before work begins.
- Assess your electrical panel early. If you’re switching from a gas furnace to a heat pump, the heat pump requires a 240V dedicated circuit. Your panel may need an upgrade, and that requires a separate electrical permit. Catching this at the estimate stage prevents a delay on installation day.
What Happens on Installation Day
The crew arrives with floor and surface coverings to protect your home during the job. After setting up, they disconnect and carefully remove the old system. Old refrigerant, if applicable, is recovered according to EPA regulations before any equipment is disconnected.
Once the old unit is out, the new system is installed to the manufacturer’s specifications and California building code requirements. Connections to ductwork, the gas line or electrical supply, and the condensate drain are made and checked for tight seals. California Title 24 generally requires a programmable or smart thermostat with residential heating installations. For heat pump systems specifically, a smart thermostat that limits supplementary electric resistance heating is required. That thermostat is wired and configured as part of the installation, not added as an afterthought.
After connections are complete, the system is started up and tested. The technician checks airflow at registers throughout the home, verifies that temperature rise across the heat exchanger falls within the manufacturer’s specified range, confirms thermostat communication, and tests safety controls including limit switches and pressure switches. The system doesn’t get signed off until it’s running correctly.
California Permits & the ECC Verification Step
California requires Title 24 compliance documentation (called the CF1R form) to be submitted with every permit application for a heating installation. For permits applied for on or after January 1, 2026, field verification is handled through the Energy Code Compliance (ECC) program. As the California Energy Commission confirms, the ECC program replaced the earlier HERS Rater process by name, but the function is the same: an independent, state-certified tester visits the home after installation to verify that the system meets California energy standards. This isn’t something we can verify on your behalf. It requires a separate third-party visit.
When ductwork is modified or replaced during the installation, duct leakage testing is also required in all California climate zones. The ducts must pass this test before the final building inspection can be signed off. We coordinate ECC scheduling and permit management on your behalf so you don’t have to navigate these requirements on your own.
What to Expect After the System Starts Running
A few things during the first hours of operation can catch a homeowner off guard. A new furnace often emits a brief odor or light haze when first started. That’s manufacturing oil burning off the heat exchanger. It’s non-toxic, it’s normal, and it clears within a few minutes. If the smell persists beyond the first few heating cycles, or if you notice anything that smells like gas rather than a faint burning odor, that warrants a call.
Before the crew leaves, your technician will walk you through the thermostat controls and settings, explain the filter replacement schedule for your specific system, and describe what normal operating sounds like. Modern systems (especially variable-speed furnaces and heat pumps) run quieter and longer per cycle than older equipment, so the sound profile may be different from what you’re used to.
For Daikin, Carrier, and Lennox equipment where we’re the original installer, our work is backed by a 1-year labor warranty. That coverage gives you a defined period after installation to address anything related to the installation itself, separate from the manufacturer’s equipment warranty.
If you’re ready to get started or just want to understand your options, Central Heating and Cooling offers free estimates with same-day scheduling whenever we can accommodate. Our bilingual team is available in both English and Spanish. Give us a call at (559) 414-8571.
