We’re Crestview Heating & Air California, and our Heating & Furnace team knows Norwalk’s neighborhoods well. From the post-war ranches near Norwalk Square to the tract homes off Studebaker Road and the residential pockets around Alondra Boulevard, we’ve spent nearly two decades working on the exact heating systems found here. Norwalk sits 15–18 miles inland in the LA Basin, far enough from the Pacific that summer afternoons routinely hit 92–96°F while Long Beach stays 8–12°F cooler. That inland heat, combined with a housing stock dominated by 1950s–1970s construction originally built with wall furnaces or minimal ductwork, creates heating and cooling challenges you won’t find in coastal cities. We don’t dispatch anonymous technicians. Owner Marcus Feldman serves as our Service Manager, which means ownership-level accountability shapes every job we run in the 90650, 90651, 90652, and 90659 ZIP codes.
Why Crestview Heating & Air California Is Norwalk’s Preferred Heating & Furnace Company
Norwalk customers have left us enough reviews to build a 4.8-star average across 250+ total ratings, and we hear the same feedback repeatedly: they want someone who understands older systems, not just salespeople pushing equipment swaps. Marcus Feldman still manages jobs in the field, so when you call Crestview, you’re getting an owner-operated company where the person answering technical questions has 19 years of hands-on HVAC experience.
Our familiarity with Norwalk’s specific housing stock saves customers time and money. We know which streets still run original 1960s single-wall galvanized ductwork, which neighborhoods were built with wall furnaces that now need full retrofits, and how the diesel particulate from I-605, I-5, and SR-91 affects filter loading in local homes. That local knowledge means fewer return trips, faster diagnostics, and solutions that actually fit your house rather than a generic playbook.
Emergency HVAC service is available for Norwalk customers when systems fail outside normal hours. We also handle commercial heating calls for small-to-mid-size properties throughout the city.
Our Heating & Furnace Services in Norwalk
Furnace Repair
Furnace repair in Norwalk typically costs $150–$700. We service gas valves, ignitors, blower motors, and control boards across all major brands. Many Norwalk homes still run original equipment from the 1970s or 1980s, and our factory training across nine brands means we don’t tell you “we don’t work on that” when we arrive. The inland heat and dust from nearby freeways can strain blower motors and flame sensors, so we check those components first on older systems.
Furnace Replacement
This is where Norwalk’s housing stock gets interesting. A typical furnace replacement here runs $3,500–$7,500, but that range assumes your home already has adequate ductwork. In Norwalk’s post-WWII tract neighborhoods, it often doesn’t. We recently replaced an aging wall furnace in a 1955 ranch home on Pioneer Boulevard with a modern Carrier split system. The original 1960s single-wall galvanized ducts were so leaky that we had to install entirely new attic ductwork to prevent comfort and efficiency issues, a common scenario in Norwalk’s older tract neighborhoods. Your system, our specialty — we’ll tell you upfront if your job requires duct retrofit, not surprise you mid-project.
Furnace Tune-Up
A furnace tune-up in Norwalk costs $80–$200 and should happen annually before heating season. Given the particulate load from I-605 and SR-91 traffic, we pay extra attention to filter condition and blower cleanliness during Norwalk tune-ups. We also test heat exchangers carefully on older furnaces, since cracked exchangers in 40-plus-year-old units are more common here than in newer construction markets.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a safety issue we take seriously. In Norwalk’s 1960s and 1970s homes, original furnaces often outlast their exchangers by decades. We inspect with visual tools and combustion analysis, and if replacement makes more sense than repair, we’ll explain why in plain terms. No scare tactics. Just facts about CO risk and repair cost versus replacement value.
Gas Valve Repair
Gas valve failure on older furnaces is common in Norwalk. Valves from the 1970s and 1980s corrode, stick, or fail to open fully, causing intermittent heat or dangerous gas flow issues. We carry compatible valves for Rheem, Goodman, Lennox, and other major brands, and we test gas pressure and manifold operation before calling the job complete. This isn’t a guess-and-replace operation — we verify combustion safety every time.

Trusted Brands We Service in Norwalk
Your system, our specialty. We maintain factory-trained compatibility across Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — nine major brands that cover virtually every furnace installed in Norwalk over the past 50 years. For common failures like gas valves, ignitors, and control boards, we stock parts locally to cut wait times. That matters in Norwalk, where a January cold snap or a 95°F October afternoon can turn a one-day repair into an emergency if you’re waiting on a back-ordered component. Owner-managed, not outsourced: Marcus Feldman oversees parts inventory and vendor relationships personally, so we’re not at the mercy of a distant dispatch center.
Common Heating & Furnace Problems We See in Norwalk Homes
- Original wall furnaces failing silently in 1950s–1960s homes. These units often have no blower, just convection heat, and when the heat exchanger cracks or the gas valve fails, the only symptom is a cold house. We find these regularly in the ranch homes near Norwalk’s historic core, and upgrading to central heat typically requires complete duct retrofit.
- Leaky 1960s single-wall galvanized ducts undermining new equipment. On older residential streets, we frequently uncover original duct runs so leaky at the seams that installing a new high-efficiency air handler without duct sealing or replacement actually worsens room-to-room comfort and spikes energy bills. It’s a costly mistake for crews unfamiliar with this specific era of LA Basin tract construction.
- Inconsistent marine layer leaving systems undersized for real heat loads. Norwalk’s inland position means the Pacific cooling that moderates Long Beach and Seal Beach often misses this city entirely. Wall furnaces and early central systems sized for milder assumptions struggle with 92–96°F summer highs, and we’ve replaced many undersized units that were never adequate for the actual microclimate.
- Accelerated filter loading from freeway particulate. Boxed in by I-605, I-5, and SR-91, Norwalk sees elevated diesel particulate levels that clog standard 1-inch filters faster than in coastal areas. We regularly find blower motors laboring against restricted airflow, especially in homes without upgraded filtration.
Pricing for Heating & Furnace in Norwalk, CA
Here’s what heating and furnace work costs in Norwalk’s market:
| Service | Price Range |
|---|---|
| Furnace Repair | $150–$700 |
| Furnace Replacement | $3,500–$7,500 |
| Furnace Tune-Up | $80–$200 |
What moves you within these ranges? For repairs, it’s part availability and accessibility — a gas valve on a 1980s Rheem in an open garage is straightforward; the same valve on a wall furnace buried in a tight closet takes longer. For replacement, duct condition is the big variable. Homes with existing, sealed ductwork land at the lower end. Homes needing complete attic duct retrofits, common in Norwalk’s 1950s–1970s tracts, run higher. We inspect ductwork during every free estimate and show you photos of what we find. No surprises, no pressure. Call (844) 560-6978 to schedule.

FAQs — Heating & Furnace in Norwalk
Yes. We route new ductwork through the attic and install a central air handler there, leaving walls intact. This is standard practice in Norwalk’s post-WWII tract neighborhoods where wall furnaces were originally installed. We recently completed this exact retrofit on Pioneer Boulevard, running all-new insulated flex duct through the attic after discovering the original 1960s galvanized ducts were too leaky to reuse. Call (844) 560-6978 and we’ll assess your specific layout during a free estimate.
Your old wall furnace heated one room directly by convection, which felt intense because you stood next to it. A new central system distributes heat evenly, which feels different — gentler, but actually more efficient and safer. If rooms feel cold or bills seem high, the issue is usually leaky ducts, not the furnace itself. In Norwalk’s older homes, original ductwork often sabotages new equipment performance. We can test duct leakage and show you the numbers.
Adding central heating to a wall-furnace home in Norwalk typically runs $4,500–$8,500, including the furnace and complete attic ductwork. The wall furnace itself is removed and the opening sealed. This is higher than a simple equipment swap because your home was never designed for ducts. We price these jobs after a full attic inspection, and estimates are free. Call (844) 560-6978 to schedule.
Yes. We service and replace gas valves on 1970s Rheem furnaces, and we carry compatible valves for this era of equipment. Rheem was commonly installed in Norwalk tract homes of that period, so this is a familiar repair for our team. We also test manifold pressure and combustion safety before finishing. If your furnace has other age-related issues, we’ll explain whether valve replacement or full replacement makes more financial sense.
Yes, short-cycling near Norwalk Square often traces back to undersized or leaky original ductwork. The 1950s–1960s homes in this area frequently have 1960s single-wall galvanized ducts that restrict airflow and cause the furnace to overheat and shut down prematurely. We measure static pressure and inspect duct runs to confirm. Sometimes duct sealing or partial replacement solves it; other times the duct system is too far gone to support a modern furnace properly. We’ll show you exactly what we find and give you options.
