Gas Furnace Repair, Maintenance, and Installation
Freedom Heating Inc. repairs, replaces, installs, and maintains gas furnaces for homes across Watsonville, Santa Cruz, and the Central Coast — from ignition problems and cold-air complaints to a full system replacement.
Not sure whether it is a repair or a replacement? Request service or an installation estimate and we will explain what we find.
If you smell gas or a carbon-monoxide alarm activates, leave the affected area immediately and contact the appropriate emergency or utility service from a safe location. Do not keep operating equipment you suspect is unsafe, and do not attempt to repair gas piping, burners, or venting yourself.
- Carbon monoxide is odorless and can be produced by incomplete combustion, a cracked heat exchanger, or a blocked flue. Working carbon-monoxide alarms on each level of the home are the reliable safeguard — not a smell test.
- Keep the furnace area clear and the flue, venting, and combustion-air openings unobstructed. Stored items against the cabinet or blocked vents can affect how the system runs.
- Gas piping, burner adjustments, and venting belong with a licensed technician. If you are unsure whether the furnace is operating safely, the right step is to turn the thermostat off and request service.
Gas furnace service covers four different kinds of work: diagnosing a problem, repairing a failed component, replacing or newly installing a furnace, and maintaining a system that is still running. Each one is quoted and scheduled differently, and we explain which one applies before any work begins.
We evaluate the furnace before recommending anything. A service call is the diagnosis and tells us what is actually wrong. A repair fixes a specific component. Maintenance is preventive inspection of accessible parts. A replacement or new installation is a larger project with equipment, ductwork, permit, and scheduling considerations.
Combustion safety comes first. Gas piping, burner components, and venting are not do-it-yourself work — if anything about the furnace or flue looks or smells wrong, stop using it and have it looked at by a qualified technician. If you smell gas or a carbon-monoxide alarm activates, leave the affected area and contact the appropriate emergency or utility service from a safe location.
Furnace Services We Provide
Furnace Repair
Diagnosis of a specific fault — no heat, cold air from the vents, ignition failure, blower or control problems — followed by repair of the component that has actually failed. We explain what we found and what the repair involves before starting.
Furnace Replacement
When repair is no longer the practical choice, we evaluate the existing furnace, the ductwork, and your comfort goals, then present equipment options for you to choose from. Replacement is quoted before it is scheduled.
New Furnace Installation
For new construction, additions, and first-time gas furnace installation, including equipment sizing and coordination with the ductwork it connects to.
Furnace Maintenance
Seasonal inspection of accessible components to identify visible wear or developing problems before they turn into a no-heat call. Maintenance lowers the risk of a surprise failure; it does not guarantee that a furnace will never break down.
What This Service Includes
- Furnace diagnosis and performance evaluation
- Ignition system inspection
- Burner and flame evaluation
- Heat exchanger visual inspection when accessible
- Thermostat and control checks
- Airflow evaluation at supply and return vents
- Gas valve and safety control inspection
- Furnace repair for identified component failures
- New furnace installation and replacement
- Preventive maintenance recommendations
Signs You May Need This Service
Common Furnace Problems We Diagnose
These are the calls we get most often. Each one has several possible causes, and the only way to know which applies is to test the system rather than replace parts on assumption.
Furnace not heating
The blower may run while the burner never lights, or the system may sit idle. Common causes include thermostat settings or mode, an ignition or pilot fault, a gas supply interruption, a safety switch that has locked out, or a control board problem. We work through the sequence of operation to find where it stops.
Furnace blowing cold air
A furnace that runs but delivers cool air is usually a combustion or control issue rather than airflow alone: the blower can start before the burner lights, the flame sensor can shut the burner down mid-cycle, or the thermostat may be set to run the fan continuously. We check ignition, flame sensing, and airflow together.

No response at all usually points to power or a safety control: a tripped breaker, the blower-door switch, thermostat batteries or wiring, a pressure switch that is not proving draft, or a board fault. Testing the startup sequence shows where the circuit stops.
Unusual noises
Rattling panels, a squealing blower, a rumbling or booming start, and a scraping sound each point somewhere different — loose access panels, blower bearings, delayed ignition, or the inducer assembly. Describing the sound and when it happens shortens the diagnosis.
Uneven heating
Some rooms warm while others stay cool when airflow is out of balance. Restricted or leaking ductwork, closed or misadjusted dampers and registers, a loaded filter, and equipment that does not match the layout of the home all produce this. We look at supply and return airflow, not only the furnace.
Signs your ductwork may be leakingFrequent cycling
A furnace that starts and stops every few minutes may be reacting to a restricted filter, a thermostat sitting in a spot that reads temperature poorly, equipment sized larger than the ductwork can handle, or a limit or pressure switch opening. Short cycling is worth diagnosing because it puts extra wear on the equipment.
Not Sure Whether It Is a Repair or a Replacement?
Tell us what the furnace is doing — no heat, cold air, noise, or short cycling — and we will help you sort out the next step. If you are planning a replacement or a new installation, ask for an estimate instead.
What to Expect
You request service or an estimate, and we confirm an appointment window.
A technician evaluates the furnace and documents the findings.
We explain what we found and present repair or replacement options.
For a replacement or new installation, we evaluate the site and provide an estimate before any work is scheduled.
Any repair, replacement, or installation work is approved by you before proceeding.
We do not promise same-day completion or immediate parts availability.
Repair or Replacement?
When evaluating your system, we consider a range of factors before recommending repair or replacement. No single factor decides on its own — we explain our findings and let you choose the option that fits your situation.
- Age and overall condition of the furnace
- Cost of the repair relative to replacement
- Repair history and frequency of breakdowns
- Heat exchanger condition and safety
- Parts availability for the existing equipment
- System efficiency and operating costs
- Comfort and heating performance
- Your plans for the property
When repair is usually the right call
- The failure is an isolated component — a flame sensor, igniter, blower motor, or control board — and the rest of the system is sound.
- The furnace is within its expected service life and parts for it are readily available.
- The heat exchanger is serviceable and the system operates within the range it should.
When replacement is worth evaluating
- The same furnace has needed repairs across consecutive heating seasons rather than once.
- Parts for the existing equipment are discontinued or hard to source, leaving you waiting on availability.
- The heat exchanger or venting raises a safety concern that repair cannot resolve.
- Heating performance or comfort no longer meets the home's needs, and a repair would not change that.
We document what we find, explain the trade-offs in plain language, and give you an estimate. We do not recommend replacement when a repair is the sound choice, and we do not ask for a decision before you have the findings.

Furnace Service Around Watsonville and Santa Cruz County
Our shop is in Watsonville, and most of our furnace work happens within a short drive of it — Freedom, Aptos, La Selva Beach, Corralitos, Soquel, Capitola, and Santa Cruz. For larger projects we also work in Salinas, Monterey, and Hollister.
Homes here ask different things of a heating system. Coastal humidity works on furnace cabinets, venting, and the connections around them. Many older houses still have their original ductwork, which affects how evenly a replacement performs. Inland evenings run colder than the coast, so short cycling and uneven heat are easy to notice quickly.
If your project involves a replacement or a new installation, we can tell you what the permit and verification requirements look like for your city before you commit to anything.
