AfterHow Much Does HVAC Cost in Baltimore?
In Baltimore, AC repair typically runs $150 – $650 and furnace repair runs $150 – $700, depending on the part and how long the technician is on site. A full AC installation usually lands between $3,500 and $7,500, and a seasonal tune-up is $80 – $200. Those are the working ranges you’ll see across the metro, whether you’re in Canton, Towson, or Glen Burnie.
Dalton Heating & Air puts the price in writing before any work starts. No written number, no work. That’s the whole point of upfront pricing, and it’s built into how we operate on every job. If a company can’t hand you a figure before it opens the panel, that’s your cue to keep looking.
HVAC Cost Breakdown (2026)
Here’s what Baltimore homeowners actually pay for common jobs. These ranges reflect typical single-family homes in the metro, not stripped-down bids from a flyer on your windshield.
| Job | Typical Range | What’s Included |
|---|---|---|
| AC repair | $150 – $650 | Diagnostic, parts, labor, written guarantee |
| Furnace repair | $150 – $700 | Diagnostic, parts, labor, written guarantee |
| AC installation | $3,500 – $7,500 | Unit, line set, labor, permit, haul-away |
| Seasonal tune-up | $80 – $200 | Cleaning, inspection, minor adjustments |
A simple capacitor swap sits at the bottom of the AC repair range. A failed blower motor or a compressor that’s gone bad sits at the top. Where you land depends on the diagnosis, the part, and whether the system is a common brand we stock on the truck or something that needs to be ordered. Furnace repair follows the same logic: a thermocouple or igniter is a small number, an inducer motor or heat exchanger issue is a larger one. The written price covers the whole job, parts and labor, before anyone starts.
Installation pricing swings more than repair pricing because it’s tied to tonnage, efficiency rating, and how much ductwork needs to be modified. Replacing a 2-ton unit in a rowhouse is a different job than sizing a 4-ton system for a larger home out in Perry Hall. The range above assumes a standard changeout. If ductwork needs to be rebuilt or a line set replaced, that’s a separate line item we’ll put in writing too.
What Affects HVAC Pricing in Baltimore
Prices here aren’t random. A few local and system-specific factors move the number more than anything else.
- Age of the equipment. Systems past the 12-to-15-year mark are more likely to need a bigger repair, and parts for older units can be harder to source. A 20-year-old furnace sometimes costs more to fix than it’s worth.
- Brand and part availability. We service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. If your system is one of those nine, we usually have what’s needed without a multi-day wait.
- Season and demand. Baltimore summers push AC calls through the roof, and the first cold snap in January does the same for furnaces. Emergency or after-hours work carries a higher labor rate than a scheduled weekday visit.
- Home age and ductwork. A lot of Baltimore rowhouses and older suburbs have ductwork that was sized for a previous system. If the ducts can’t handle a new unit, that’s extra work, and it needs to be priced honestly.
- Efficiency rating on installs. A 14 SEER unit and an 18 SEER unit don’t cost the same. Higher efficiency costs more up front and less to run each month. That tradeoff is worth talking through before you buy.
- Electrical and access. A system tucked in a tight crawlspace or attic takes longer to reach and work on than one in a clean basement. Access affects labor hours, and labor hours affect the price.
How to Save on HVAC
The cheapest HVAC bill is the one you avoid. Here’s what actually works in this market.
- Get the tune-up before the season, not during it. A $80 – $200 tune-up in April costs far less than a mid-July emergency call. It also catches small problems, a dirty coil or a weak capacitor, before they turn into a $600 repair.
- Change your filter on schedule. A clogged filter makes the system work harder and shortens its life. This is the one piece of maintenance you can do yourself, and it matters.
- Fix small things early. A strange noise or a system that runs nonstop is cheaper to address now than after a full failure. The longer you wait, the bigger the bill.
- Ask for the written price before work starts. Any reputable company will put it in writing. If the number changes at the door, that’s a problem, and you should walk. Dalton Heating & Air prices in writing on every job, no exceptions.
- Weigh repair vs. replace honestly. If a repair is more than a third of the cost of a new system on equipment that’s already near the end of its life, replacement often makes more sense. We’ll tell you straight, even when it means a smaller ticket for us.

FAQs – HVAC Cost
How much does AC repair cost in Baltimore?
AC repair in Baltimore runs $150 – $650 for most jobs, including the diagnostic, parts, and labor. A capacitor or contactor is on the low end; a blower motor or compressor is on the high end. Every repair from Dalton Heating & Air is guaranteed in writing for a full year. If it fails in that time, we come back at no charge. Call (361) 306-9515 for an exact quote, and the estimate is free.
How much does furnace repair cost in Baltimore?
Most furnace repairs land between $150 and $700. A thermocouple or igniter is a small job; an inducer motor or heat exchanger is a larger one. Because it’s a gas appliance, this isn’t a repair to attempt yourself. Any work on the burners, gas valve, or flue needs a trained technician. Call (361) 306-9515 for a written price before any work begins.
How much does a new AC unit cost in Baltimore?
A full AC installation in the Baltimore area typically costs $3,500 – $7,500. That range covers the unit, line set, labor, permit, and haul-away of the old equipment. Tonnage, efficiency rating, and any ductwork changes move the number. We’ll size the system for your home and put the full price in writing before we start. Call (361) 306-9515 for a free estimate.
Is it cheaper to repair or replace my HVAC system?
Repair is usually cheaper if your system is under 10 years old and the fix is a single part. Once a system passes 12 to 15 years, or a repair costs more than about a third of a new install, replacement often wins on total cost. We’ll run both numbers for you and tell you which one makes sense, free of charge.
How much is an HVAC tune-up in Baltimore?
A seasonal tune-up costs $80 – $200 in the Baltimore market. It includes cleaning the coils, checking refrigerant charge and electrical connections, and adjusting anything that’s drifted. Done once a year, it’s the cheapest way to keep repair bills down. Call (361) 306-9515 to schedule one. A real person answers, day or night.
