Why Dalton Heating & Air Long Beach Is La Mirada’s Preferred Furnace Repair Company
Dalton Heating & Air operates under The Garrison Standard, the same code we’ve followed since 2003. That means every tech arrives inside the stated window, puts the price in writing before touching a tool, and leaves your floor cleaner than they found it. We’re a Furnace Repair company that serves La Mirada homes with the same discipline on a $200 ignitor swap as on a full system replacement.
When a furnace fails in La Mirada, the problem usually isn’t just the furnace. This city’s 1950s and 60s housing stock brings its own set of issues: original galvanized ducts that leak, tight utility closets, and panels that weren’t sized for modern blower motors. Our techs know what they’re walking into before they ring the bell, because they’ve worked these streets and these floor plans hundreds of times.
Every Dalton tech is background-checked and uniformed. Owner Marco Benitez holds the team to the same standard on every dispatch to La Mirada, from the first call to the written guarantee you get when the job is done. Dispatch is coordinated from our Los Angeles office, and the crews serving La Mirada live and work in this part of the county.
Styles & brands we work with







Heating Repair in La Mirada
Heating Repair in La Mirada is what we do most often from late October through early spring, when nights drop into the 40s and a dead furnace turns a tract home cold fast. The job means diagnosing why the system isn’t making heat, replacing or repairing the failed part, and confirming the whole system runs safely before we leave. Costs run $150 to $700, and the exact figure goes in writing before we start.
Limit Switch and Overheating Faults
A furnace that fires and shuts down on repeat often has a tripping limit switch. On older La Mirada systems, the underlying cause is frequently blocked return air, a dirty blower wheel, or ducts that have collapsed in a low-slope attic.
Ignitor and Burner Service
Hot surface ignitors wear out. It’s a simple mechanical fact. On a cold morning in La Mirada, a cracked ignitor means no heat, and it’s a repair we typically complete in one visit with parts on the truck.
Boiler Repair in La Mirada
Boiler Repair in La Mirada is a less common call than furnace work, but the homes that have boilers tend to be the older ones here, and the issues are always urgent when the system quits. A boiler that won’t fire or won’t circulate leaves a house cold in a hurry. Repairs run $150 to $700, with the same written price and one-year written guarantee as every other Dalton job.
Circulator Pump and Zone Valve Work
When a boiler runs but radiators stay cold, the circulator pump or a stuck zone valve is usually the culprit. These are straightforward repairs on most La Mirada boiler setups, and we carry common replacement parts on the truck.
Pressure and Expansion Tank Checks
Low system pressure or a waterlogged expansion tank will shut a boiler down or make it surge. We test both during any boiler call in La Mirada, because fixing the symptom without checking the tank means a callback waiting to happen.
Trusted Brands We Service in La Mirada
Our techs are factory-trained on all nine major residential HVAC brands, including Carrier, Trane, Lennox, and American Standard. That means when a Lennox furnace off Santa Gertrudes Avenue throws a fault code, we read it correctly and fix it the first time. We keep common parts stocked for La Mirada dispatches, so most repairs don’t wait on a parts run. If your furnace is a Carrier, a Trane, or any other major name, we can service it.

AfterCommon Furnace Repair Problems We See in La Mirada Homes
- Cracked heat exchangers in original floor furnaces. These 1960s units crack as the metal fatigues, and carbon monoxide can enter a closed-up home before a detector trips. If we find a crack, we red-tag the unit and walk you through replacement options.
- Corroded galvanized ducts in low-slope attics. A La Mirada attic hits 140°F in July, and that heat makes old ductwork sweat, rust, and separate at the seams. A furnace can run perfectly and still leave rooms cold because the ducts are bleeding air.
- Undersized 100-amp panels tripping control boards. Modern ECM blower motors draw differently than old PSC motors did, and a 1950s panel sometimes can’t deliver clean startup current. Symptom: intermittent shutdowns, fault codes that don’t repeat.
- Burnt-dust smell at first firing each fall. Summer dust settles on the heat exchanger, and the first long run of the season burns it off. One cycle is normal. A persistent smell means deeper buildup and needs attention.

FAQs About Furnace Repair in La Mirada
Because the furnace was fixed but the ductwork wasn’t. In La Mirada’s 1950s and 60s tract homes, original galvanized ducts in a 140°F attic sweat, corrode, and separate at the joints. A repaired furnace can produce all the heat it’s rated for and still lose half of it before it reaches the back bedrooms. The fix is duct sealing and insulation, not another furnace repair. Call (562) 512-7423 and we’ll test your system’s static pressure before recommending anything.
Usually not worth repairing. A 40-year-old floor furnace has already outlived its design life, and the heat exchanger cracks that come with age are a carbon monoxide risk in a closed-up winter home. Replacing it with a central system costs more up front, but you get even heat distribution and a system sized to your house. The written price we give you includes all the load calculation work. Estimates are free at (562) 512-7423.
Yes. We use a combustion analyzer and a visual inspection camera to check for cracks and CO leakage without pulling the whole exchanger out of a cramped closet. If we can’t get a clear read, we’ll tell you that and explain what a full inspection involves before any work begins.
The dust that settled on the heat exchanger over the summer burns off during the first long heating cycle. That’s normal for the first run of the season. If the smell persists past a cycle or two, or smells more like plastic or electrical, shut the system down and call (562) 512-7423. That’s a different problem.
Sometimes, but not always cleanly. The ducts are usually the bigger issue. Original galvanized ducts in a low-slope attic lose enough conditioned air that a new high-efficiency furnace can’t overcome the static pressure imbalance. The 100-amp panel can also matter, since a modern ECM blower motor’s startup draw may trip an undersized circuit. A proper assessment tells you what needs to be done, and what can wait. Call (562) 512-7423 for a written assessment.
