HVAC Company in Overlea, MD
Dalton Heating & Air handles HVAC repair and installation across Overlea, MD, with written pricing before any work starts and a full-year written guarantee on every repair.

Call (361) 306-9515 and a live person answers, 24/7.
Why Overlea Homes Are Different
Overlea sits in northeast Baltimore County, where the terrain rolls enough to matter for airflow and drainage around outdoor units. Many homes here were built from the 1940s through the 1980s, so we see a real mix of ductwork: some original galvanized, some flex duct retrofitted, some rooms with registers that were never quite balanced. That means a simple repair often requires checking static pressure and airflow before we quote a part, because the right fix in one Overlea house can be the wrong fix in the one next door.
Summers in Overlea are the kind that make a failed AC a genuine health concern – upper-floor bedrooms in brick homes can run 10 to 15 degrees hotter than the rest of the house. Winters bring stretches where a furnace that hiccups at 4 a.m. leaves a family without heat by morning. On top of that, many Overlea streets sit close enough to full-grown trees that condenser coils collect cottonwood and leaf debris faster than homeowners expect. We account for all of that on the first visit, not the third.
Permits here follow Baltimore County rules, and most repair work doesn’t require one – but any time we touch gas piping or a heat pump’s refrigerant lines, we do the job by the book and can pull the paperwork if the township asks. The Garrison Code is our operating standard: arrive inside the window, price in writing before starting, do the job right, leave the site clean, and stand behind the work for a full year.
Our Main Overlea Services
Three services account for nearly every call we run in Overlea: AC repair through the summer months, furnace repair when the temperature drops, and heat pump installation when a system has finally had enough. Each has its own page here, with the prices Overlea homeowners actually pay.
AC Repair in Overlea
Most AC repairs in Overlea run $150 to $650, depending on what’s failed. A blown capacitor or a clogged condensate line is quick work; a leaking evaporator coil is a bigger job. Maryland’s humidity makes a properly charged system critical – a unit that’s low on refrigerant will struggle to pull moisture out of the air even when it blows cold. We service all nine major brands and keep common Carrier, Trane, and Lennox parts on our trucks. Read more at AC Repair in Overlea.

Heat Pump Installation in Overlea
Heat pumps are a strong fit for Overlea homes because they handle both cooling and heating, and Baltimore County’s winter temperatures rarely drop below what a modern heat pump can handle efficiently. A full installation runs $3,500 to $7,500, and we write that price down before any work begins – no surprises at the door. Load calculation matters here: we size the system to the house, not to a rule of thumb. See Heat Pump Installation in Overlea.

Furnace Repair in Overlea
Furnace repair in Overlea runs $150 to $700 for most jobs. The common failures we see in this area are ignitors, flame sensors, draft inducer motors, and gas valves – parts that fail without much warning. If your furnace is short-cycling or the burners won’t stay lit, we’ll diagnose it in one visit and put the repair price in writing before turning a wrench. Details at Furnace Repair in Overlea.
