Carrier HVAC in Boston, CA | Dalton Heating & Air
We service Carrier furnaces, ACs, and heat pumps across Boston, and the cost of a Boston AC Repair typically runs $175 – $765 for AC work and $175 – $825 for furnace work. Dalton Heating & Air is an independent Carrier service provider, not a manufacturer-authorized shop, which means our advice never comes with a sales quota attached. Marco Benitez leads our team, and live phone support is answered by a real person around the clock at (361) 306-9515.
Why Boston Residents Choose Us for Carrier Service
Our technicians have been inside Carrier equipment across Boston for over two decades. We know which Infinity series boards fail after voltage spikes in older neighborhoods, which Comfort series capacitors swell in salt air near the water, and which furnace heat exchangers crack after enough cold winters. Being independent matters here. We’re not pushed by Carrier to sell new equipment, so when a repair will hold, we say so in writing. Marco Benitez grew up in East Los Angeles and trained at Los Angeles Trade-Technical College, where he learned refrigerant systems, ductwork design, and load calculations. He drills the same discipline into our Boston techs: diagnose the failure, explain it in plain English, and price it before any work starts. Every Carrier call includes our written 365-Day Done Right Promise and a written guarantee on the repair. If the work doesn’t hold, we return at no charge. For the full range of Carrier sales & service, we bring the same standard to every job.
Common Carrier HVAC Problems We Solve in Boston
- Infinity series control board failures. Boston’s older neighborhoods run on overhead power lines, and voltage spikes there are harder on Infinity boards than on simpler controls. We keep replacement boards on our trucks because we see this often enough to stock for it.
- Heat exchanger cracks in Performance and Comfort furnaces. A Boston winter cycles a furnace hard, and after enough years, the metal fatigues. A cracked heat exchanger can leak carbon monoxide, so we tell homeowners plainly: this one is not a wait-and-see repair.
- Capacitor swelling in AC condensers near the coast. Salt air accelerates capacitor failure in South Boston and East Boston more than inland neighborhoods. The symptom is usually a condenser that hums but won’t spin up. We replace the capacitor, test the compressor, and tighten every connection while we’re there.
- Refrigerant leaks at brazed joints in Carrier coils. Vibration and age loosen those joints over time. A slow leak drops cooling capacity long before the system stops entirely. We find the leak, repair the joint, and recharge to manufacturer spec. That’s a refrigerant recharge, which is topping off the cooling fluid your system needs to reach set temperature.
- Heat pump breaker trips on startup. We recently serviced a Carrier Infinity 24ANB7 heat pump in Brighton that kept tripping its breaker. The culprit was a failing run capacitor and a loose wire in the outdoor unit. OEM capacitor in, connections tightened, and the system has run smooth since. The homeowner was glad to hear the 8-year-old unit had plenty of life left.
Carrier Service in Boston: What Local Conditions Mean for Your Equipment
Boston’s older housing stock often has undersized electrical panels that can’t handle the inrush current of modern high-efficiency Carrier systems without a soft-start kit. Inrush current is the brief surge of electricity when a compressor first kicks on. A high-efficiency Infinity or Performance unit can pull more than a 100-amp panel in an older triple-decker or a two-family on a side street in Jamaica Plain is ready to give. We check the panel rating and the existing wire gauge on every installation estimate, and we quote a soft-start kit as a line item when the math says it’s needed. Skipping that step means a system that trips breakers on the hottest afternoons, and a breaker that trips repeatedly is a fire risk, not a nuisance. It’s the kind of detail a generic Carrier page won’t catch and a generic Boston page won’t connect to the equipment. We catch it because we’ve been reading Boston panels and Carrier nameplates side by side for years. Our coverage spans the full Boston service area, and we treat every street, from Brighton to Dorchester, with the same panel-level attention.
Carrier Models & Products We Service in Boston
We work on the full Carrier residential lineup. That includes Infinity series units like the 24ANB7 and 25HNB6, Performance series models like the 24ACC6 and 25HPA6, and Comfort series equipment such as the 24ABB3 and 24ABC6. Carrier ductless mini-splits, including the 40MBF and 40MAQ, are in our wheelhouse too. When we replace a part, we use OEM Carrier components whenever they’re available. When OEM is backordered, we’ll turn to an aftermarket supplier only if the part meets or exceeds the original spec. Our vans carry the most common Boston failure parts: capacitors, contactors, control boards, and ignitors. That local stock means a Boston Heat Pump Installation or repair that would take a week waiting on a part often gets done the same day.

FAQs – Carrier HVAC in Boston
Error code 42 on a Carrier Infinity system points to an outdoor unit communication fault between the system’s control board and the outdoor equipment. It’s often a wiring or voltage issue rather than a dead board. We diagnose it by checking line voltage, low-voltage signal wiring, and the board itself, then repair the actual cause. Call (361) 306-9515 and we’ll schedule a diagnosis.
Once a year, before the heating season, is right for Boston. The cold months are long enough that a furnace running with a dirty flame sensor or a weak ignitor will fail at the worst possible time. A tune-up runs $95 – $235 and includes a written report of what we found.
Yes. Our phones are answered by a live person 24/7, and we run weekend service calls across Boston. A failed AC in a Boston summer is a health risk, especially for elderly residents and young children, so we treat it that way. Call (361) 306-9515 any hour and you won’t get a voicemail queue.
In most cases a cracked heat exchanger means a new furnace is the honest recommendation. The part is expensive, and the labor to access it is extensive. If your Carrier furnace is under 10 years old and the heat exchanger is still under warranty, replacement can make sense. If it’s older, that repair money is better spent toward a new system with a full manufacturer warranty.
Sizing depends on square footage, insulation, window exposure, and the building’s electrical panel capacity. Triple-deckers often have older panels and separate living spaces, so the answer is rarely one size fits all. We run a load calculation on every installation estimate, because sizing equipment to a house means doing the math, not just swapping in whatever was there before. Call (361) 306-9515 for a written estimate.
