AfterHVAC Company in Baltimore, MD
Dalton Heating & Air is an HVAC company serving Baltimore, MD with repair and installation work priced in writing before any job begins. Baltimore’s mix of 1920s row homes, mid-century split levels, and newer suburban builds means we see different equipment, ductwork, and venting challenges from one street to the next. Most repair calls in Baltimore run $150 to $650 for AC work and $150 to $700 for furnace repair, depending on the part and the system. Call (361) 306-9515 and a live person answers, 24/7.
Why Baltimore Homes Are Different
Baltimore housing stock runs old in the center and newer at the edges, and the age of the structure changes what we find inside. The brick row homes in neighborhoods like Canton, Fells Point, and Federal Hill were built before central air was standard, so many run on later add-on systems with ductwork routed through closets, dropped ceilings, and old chimneys. Those systems work, but the duct runs are often undersized for the square footage, which pushes static pressure higher and shortens blower motor life. In the postwar neighborhoods like Hamilton, Lauraville, and Parkville, we see more conventional split systems, but many are past their fifteenth year and running on original evaporator coils.
Climate matters too. Baltimore summers are humid, and humidity loads make an undersized AC work harder than the thermostat suggests. A system that cools to 74 degrees but leaves the air damp is often short-cycling or low on charge. Winter swings between mild and bitter, so furnaces need to light reliably in shoulder season and hold up through single-digit stretches. The freeze-thaw cycle also moves pad-mounted condensers in the county neighborhoods, and we check level and line-set chafing on every AC call. Baltimore permits are generally straightforward for like-for-like equipment swaps, but ductwork changes or heat pump retrofits can require a mechanical permit. We handle the paperwork and confirm what’s needed before we start.
Our Main Baltimore Services
Baltimore homeowners call us most often for three things: an AC that stopped cooling, a furnace that will not stay lit, and a plan to replace an aging system with a heat pump. Each has its own Baltimore page with full pricing, common failures, and what to expect on the day of the job.
AC Repair in Baltimore
When a Baltimore AC quits in July, the first thing most homeowners want is a real diagnosis, not a sales pitch for a new unit. Our technicians arrive with common parts for the major brands on the truck, test the capacitor, contactor, refrigerant charge, and airflow before recommending any repair, and put the price in writing before touching the system. Humidity makes Baltimore AC failures worse: a coil that is icing at 10 PM was often low on charge or starved for airflow all afternoon. Every repair carries a written guarantee for a full year, and if it fails in that time, we return at no charge. Read the full breakdown at AC Repair in Baltimore.
Heat Pump Installation in Baltimore
Baltimore’s winters are cold enough that heat pump sizing matters, and the older housing stock often needs an honest look at the existing ductwork before we quote a system. A heat pump replaces both a furnace and an AC in one unit, which appeals to Baltimore homeowners who have a single aging gas furnace paired with an older condenser. We calculate load, check the electrical panel capacity, and write the installation price before the job is scheduled. Installations include a full-year written guarantee and our 365-Day Done Right Promise. Details on equipment options and Baltimore rebates are on Heat Pump Installation in Baltimore.
Furnace Repair in Baltimore
Baltimore furnaces tend to fail when the first real cold front hits, and the most common call we take is a furnace that lights and then shuts off inside a minute. That is usually a dirty flame sensor – a quick fix – but it can also be a failing inducer motor or a cracked heat exchanger, which is a different conversation. Our technicians carry igniters, flame sensors, pressure switches, and control boards for the brands we service, so a diagnosis and repair often happen on the first visit. The price is in writing before any work starts, and the repair is guaranteed in writing for a full year. See Furnace Repair in Baltimore for the full guide.

What pushes a Baltimore repair toward the top of the range is usually part availability and system age. Some original parts for 20-year-old furnaces in row homes are no longer made, so the repair may require a universal part and added labor. Regardless of what we find, you get a written price before any work begins, and that price does not change at the door.
