Serving the Historic District
HVAC & Plumbing in Historic Downtown McKinney
Our shop sits minutes from the square. Comfort work on century-old homes is different, and it's work we've been doing here since 1958.
The neighborhoods around McKinney's courthouse square hold some of Collin County's oldest housing stock, Victorian, Craftsman, and early-20th-century homes protected by the city's historic districts, which the McKinney City Council established by ordinance in the 1980s. Burnside has been headquartered in McKinney since 1958; these streets are home turf.
Heating and cooling a 100-year-old home is a different job than a 2005 two-story: there may be no ductwork at all, framing cavities are shallow, and exterior changes visible from the street are regulated. We do sensitive retrofits, high-velocity and ductless systems, carefully placed condensers, and plumbing that respects original construction.
What historic McKinney homes are working with
Pier-and-beam foundations, balloon framing, plaster walls, and minimal insulation are the norm. Many homes have been retrofitted over the decades, sometimes well, sometimes with undersized closet air handlers and duct runs that starve the far rooms. Mini-split and small-duct high-velocity systems are often the right modern answer because they condition without tearing up original walls.
Plumbing in these homes can include galvanized supply lines and cast-iron or clay sewer laterals near the end of their life. Camera inspection before buying or remodeling a historic home is some of the cheapest insurance in McKinney.
What we get called out for most in Historic Downtown McKinney
No ducts, shallow walls
Original homes were built for windows and ceiling fans, not central air. Ductless mini-splits and high-velocity systems cool without destroying plaster or trim.
Visible-from-street rules
In the Historic Overlay District, exterior work visible from the public right-of-way needs city review before a permit. Condenser placement and screening matter, we plan for it.
Galvanized supply & old laterals
Low pressure at fixtures and rusty water point to galvanized pipe; frequent backups point to clay or cast-iron laterals. We camera first, then recommend.
Knob-and-tube era load limits
Older electrical services may need evaluation before adding modern high-efficiency equipment, we coordinate so your new system has the power it needs.
Historic district rules for exterior HVAC work
Verified July 2026 against City of McKinney publications
- McKinney established its historic districts by ordinance in the 1980s. Within the Historic Overlay District, a Certificate of Appropriateness (COA) is required before a permit for new construction, alterations, or changes in materials visible from the public right-of-way, reviewed by the city's Historic Preservation Office against the Secretary of the Interior's Standards.
- General maintenance and in-kind repairs typically do not require a COA, but the city recommends consulting the Historic Preservation Office before starting work. Interior changes are not monitored.
- A City of McKinney mechanical permit is still required for HVAC equipment replacement, separate from any COA. Burnside is registered with the city and handles permitting; where equipment placement is visible from the street, we help you confirm COA requirements before installation day.

Historic Downtown McKinney HVAC & plumbing questions we hear a lot
Can I add central air to a historic McKinney home?
Almost always, yes, the question is how. Small-duct high-velocity systems thread through existing cavities; ductless mini-splits condition room by room with no ducts at all. The right answer depends on your floor plan, and placement of outdoor equipment may need city review if it's visible from the street.
Do I need a Certificate of Appropriateness to replace my AC?
A COA applies to exterior work visible from the public right-of-way in the Historic Overlay District. Replacing a condenser in an existing screened side-yard location is usually maintenance; adding new visible equipment can require review. The city's Historic Preservation Office makes the call, we help you check before work begins.
My water pressure is terrible. Is a repipe my only option?
If the home still has galvanized supply lines, pressure loss comes from decades of internal corrosion, and a repipe is the durable fix. We confirm with a pressure test and pipe inspection first, sometimes the culprit is just a failed PRV or a partially closed valve.
How do I know if my sewer lateral needs replacement?
Repeated backups, slow drains throughout the house, or soggy spots in the yard. A camera inspection shows exactly what's down there, bellies, root intrusion, or collapsed clay, before you spend on excavation. We offer a free drain camera inspection where there's an accessible clean-out (verified current offer).
Are high-efficiency systems worth it in an old, leaky house?
Equipment efficiency helps, but in historic homes the bigger wins usually come from air sealing, attic insulation, and duct improvements first. We'll tell you where the next dollar actually goes furthest, that's the honest order of operations.
