Lennox HVAC in Baltimore, CA | Dalton Heating & Air
We provide independent Lennox HVAC service serving Baltimore, MD. The one thing that makes our Lennox work here different: we know Lennox equipment fails in specific, diagnosable ways inside Baltimore’s rowhomes, and we stock the parts to fix those failures on the first visit. Marco Benitez and our technicians have spent years working on G-series furnaces, Signature Collection heat pumps, and 13ACX condensers in homes where space is tight and airflow is everything.

Why Baltimore Residents Choose Us for Lennox Service
We’re not a manufacturer-authorized dealer. We’re an Lennox sales & service provider who fixes what other techs misdiagnose. The difference is specificity. A Lennox G60 furnace tripping its rollout switch is usually a cracked hot surface ignitor or a sooted flame sensor, not a bad control board. A Signature Collection unit locking out on a communication error usually traces to a specific voltage drop on the thermostat wire, not a failed motor. We know these failure signatures because we see them every week.
Marco Benitez learned the trade at Los Angeles Trade-Technical College, where the hands-on lab work covered refrigerant systems, ductwork design, and load calculations; the math behind sizing equipment to a house, not just swapping out whatever was there before. That training is why our Lennox calls in Baltimore start with testing, not guessing.
When a homeowner calls us about a Lennox unit that won’t hold temperature, we check static pressure, heat rise, and gas pressure before we ever order a part. That sequence is what catches the real problem the first time. Our trucks carry Lennox-specific control boards, ignitors, and blower motors, so a repair is rarely a second visit in Baltimore.
Common Lennox HVAC Problems We Solve in Baltimore
- Cracked hot surface ignitors in G60/G61 furnaces. These brittle silicon-carbide elements crack from Baltimore’s humid summer-to-winter swings. When the ignitor can’t glow hot enough, the furnace tries to fire, fails, and trips the rollout switch. We keep OEM ignitors on the truck.
- Cracked secondary heat exchangers in older G24/G26 units. These aren’t always noisy. They get flagged during a tune-up when CO levels start creeping up. If you have a G24 or G26 that’s 15-plus years old, this is the failure to watch for. We’ll show you the crack and give you a straight repair-or-replace number.
- Seized condenser fan motors in 13ACX/14ACX condensers. Baltimore’s winter freeze-thaw cycles and salt air are hard on outside fan motors. The motor bearings wear out, the fan stops, and the compressor overheats and trips its thermal overload. We replace these with OEM-equivalent motors that match the original specs.
- Faulty control boards in Signature and Elite variable-speed systems. The SL280V, EL296V, and EL18XCV run on communicating control boards that can lock out when voltage fluctuates. Wisconsin winters and older electrical panels in Baltimore’s housing stock make this more common than it should be.
- Restricted return air in rowhome closets. Not a parts failure, but a Baltimore-specific one. Lennox furnaces and air handlers tucked into tight, unvented closets run high static pressure, which overheats the heat exchanger and shortens blower motor life. We measure this on nearly every Baltimore call.
Lennox Service in Baltimore: What Local Conditions Mean for Your Equipment
Baltimore’s housing stock includes thousands of rowhomes with Lennox furnaces and air handlers tucked into tight, unvented closets. Return-air restrictions and overheating are chronic in these homes. When we get a no-heat call in Baltimore and the Lennox unit is in a closet with a louvered door that’s been blocked by storage or a return duct that’s been crushed behind drywall, we don’t start with a circuit board replacement. We start with a static-pressure test. A furnace that can’t pull enough air runs hot, trips limits, and cracks heat exchangers years before it should. That’s the difference between a parts-swapper and a technician who understands the house as part of the system. In neighborhoods across Baltimore, this single test explains more intermittent lockouts and short-cycling complaints than any failed component.
A Canton rowhome owner called us when their Lennox G60 furnace kept tripping its rollout switch. Our tech found a cracked hot surface ignitor and a sooted flame sensor, replaced both with OEM parts, and then measured a 0.9-in. w.c. return static that was bogging down the blower. After clearing a crushed return duct in the closet, the system ran a steady 110°F rise and passed a CO safety check. That’s the kind of repair that actually holds.
Lennox Models & Products We Service in Baltimore
We service the full Lennox residential lineup, from older G-series furnaces to current Dave Lennox Signature Collection equipment. That includes the SL280V and SL297NV variable-speed gas furnaces, the Merit Series ML180, ML193, and ML14XC1, the Elite Series EL296V and EL18XCV, and the 13ACX and 14ACX air conditioners.
Parts policy matters on Lennox equipment. We use OEM Lennox parts for all critical ignition, control, and heat-exchanger components. Premium aftermarket equivalents from US Motors and Packard are used only for standard motors and capacitors where the spec is identical. We don’t put a generic part into a safety-critical spot to save a few dollars. Our Baltimore truck stock includes the control boards, ignitors, and blower motors that get Lennox systems running the same day.
Lennox Service Pricing in Baltimore
Here’s what Lennox service costs in Baltimore, based on what we actually see:

FAQs – Lennox HVAC in Baltimore
Usually not. On a Lennox G60 or G61 in Baltimore, a tripping rollout switch is most often a cracked hot surface ignitor or a sooted flame sensor, not a failed heat exchanger. We test the ignitor’s resistance and inspect the heat exchanger for cracks before telling you what’s wrong. If the heat exchanger is cracked, we’ll show you the crack and give you a repair-versus-replace price. Call (361) 306-9515 and we’ll diagnose it the same day.
Yes. Our Baltimore service trucks carry OEM Lennox ignitors for the G60, G61, and Merit Series furnaces, plus control boards for the Signature and Elite variable-speed lines. That’s why most Lennox repairs in Baltimore are completed on the first visit. Call (361) 306-9515 and we’ll tell you what we have before we leave the shop.
Because Heat Pump Installation in Baltimore requires knowing that heat pumps move heat rather than create it, and Baltimore’s winter air holds less heat to move. When outdoor temperatures drop into the teens and single digits, even a well-charged Lennox heat pump loses capacity. Add a restricted return in a rowhome closet, and the system works harder for less output. We check refrigerant charge, defrost operation, and static pressure to find whether the issue is the system or the ductwork. Call (361) 306-9515 for a diagnostic that separates equipment problems from airflow problems.
Yes, as an independent provider we can replace a failed part under the manufacturer’s parts warranty. We’re not a Lennox-authorized dealer, but we work with Lennox warranties every week and we’ll file the claim for you. You cover the labor; the part is covered if it’s within warranty. Call (361) 306-9515 and we’ll verify your warranty status before we order anything.
Every fall. Baltimore’s humid summers and freeze-thaw winters are rough on heat exchangers, ignitors, and burner assemblies. A fall tune-up catches a small crack or a weak ignitor before it becomes a no-heat call in February. Our tune-up runs $80 – $200 and includes a CO check, gas pressure verification, and a written report of what we found. Call (361) 306-9515 to schedule.
