Keller Plumbing & Heating in Baltimore: Same-Day Service and Heating Repair
Keller Plumbing & Heating is a licensed, full-service plumbing and HVAC contractor operating in Baltimore, handling both emergency calls and scheduled maintenance for residential customers across the city and surrounding counties.
What Keller Plumbing & Heating actually is
Keller operates as a dual-trade shop: plumbing and heating work under one roof, which means a homeowner dealing with a burst pipe or a failing water heater can call one number instead of juggling two contractors. The company is Maryland-licensed and insured, required credentials for any plumbing work that touches water supply lines or drainage systems in Baltimore. They field routine repairs, replacements, and new installations, and they take emergency calls outside standard business hours.
Services and pricing
Keller handles common plumbing jobs: leak repair, drain cleaning, water heater replacement, fixture installation, and toilet repair. Heating services include furnace repair, boiler maintenance, and system replacement. The company offers both emergency (24/7 availability) and scheduled service.
Pricing structure: a service call carries a diagnostic fee (typically $75–$100 for plumbing, though this amount is verified best by phone call given seasonal and market variation), and labor runs roughly $85–$125 per hour depending on job complexity and time of day. Water heater replacement ranges from $1,200 to $2,500 installed, depending on tank size and fuel type (gas vs. electric). Drain cleaning by machine costs $150–$300 for a single line. Many Baltimore plumbers charge a premium for evening or weekend calls; Keller's emergency surcharge applies after hours.
The company offers maintenance contracts for heating systems, typically annual tune-ups in fall before the season starts. Annual HVAC maintenance runs $150–$250 and usually includes filter change, safety inspection, and efficiency check.
How Keller compares to other Baltimore plumbing options
Baltimore has independent plumbers scattered across neighborhoods (Fells Point, Canton, Federal Hill, and the outer counties each have local operators) and larger regional chains like Mr. Rooter and Roto-Rooter, which operate citywide and tend toward higher service call fees ($100–$150) but offer stronger guarantees. Keller's dual-trade model differs from single-trade shops: if your heating fails in January and your basement line backs up the same week, a combined plumber-HVAC contractor handles both under one service relationship, avoiding coordination friction. However, large chains often staff more trucks for faster response times in emergencies.
For routine maintenance and minor repairs, independent plumbers in your neighborhood may charge less per hour. For guaranteed same-day emergency response and a broader service menu (plumbing plus heating), Keller and comparable dual-trade shops justify a slightly higher rate.
Who Keller suits and who it does not
Keller is right for homeowners who want a single point of contact for plumbing and heating issues, particularly those in older Baltimore rowhouses where water lines and heating systems are equally aged and failure-prone. Households that value not having to vet and schedule two separate contractors benefit most. The 24/7 emergency availability works well for anyone dealing with a burst pipe or dead furnace in winter.
Keller is less ideal for very budget-conscious customers seeking the lowest hourly rate, or for new construction and large commercial projects, where Keller typically does not operate.
What the first visit involves
A technician arrives at the scheduled time (or within the emergency window for after-hours calls), diagnoses the problem, and provides a written estimate before starting work. For water heater replacement or major repairs, this diagnostic step is separate from the repair itself, so the customer has a clear picture of costs upfront. For emergency calls, the technician explains the situation on-site and answers questions before committing to the full job.
Hours, location, and logistics
Keller operates Monday through Friday, 7 a.m. to 4:30 p.m. for scheduled service. Emergency calls are available 24/7, including weekends, with an after-hours surcharge. The company is based in Baltimore County, but services Baltimore City proper; confirm service area boundaries for your specific address before calling.
Keller Plumbing & Heating serves the Baltimore plumbing market by combining two essential home systems under licensed, insured management, a practical choice for a city where aging infrastructure makes both plumbing and heating failures routine.
