Lashbrook Mechanical was built on advanced furnace diagnostics and performance-driven system design throughout the Ann Arbor area. With over 15 years in the HVAC industry — including formal training, NATE certification, heat pump specialization, and Department of Energy–recognized electrification education — our foundation is rooted in understanding how heating systems actually perform in Michigan’s climate.
In Ann Arbor, where efficiency standards, A2Zero initiatives, and rebate qualifications matter, installation is not guesswork. We evaluate total external static pressure, duct design, combustion performance, fuel delivery, load requirements, and system compatibility before recommending any major decision.
We do not treat furnaces and heat pumps as simple equipment swaps. We treat them as engineered systems.
That technical foundation is what separates professional HVAC system design from rushed replacements. It is why our installations are rebate-ready, code-compliant, and performance-tested before we leave your home.
Properly sized and airflow-balanced systems engineered for Michigan winters.
Performance testing that prevents mid-season breakdowns.
Ann Arbor homes range from historic downtown properties to mid-century subdivisions and newer high-performance builds. Many older systems are oversized, poorly balanced, or operating under high static pressure — leading to uneven heat, noise, and unnecessary energy use.
At Lashbrook Mechanical, we approach furnace performance analytically. We evaluate airflow, duct design, static pressure, combustion quality, and system sizing before making recommendations. Our goal isn’t simply replacing equipment — it’s correcting performance issues and delivering stable, efficient heating that holds up through Michigan winters.
When installed and commissioned correctly, a furnace should operate quietly, efficiently, and consistently — not cycle excessively or struggle to maintain temperature.
Whether you need urgent furnace repair, seasonal maintenance, or a complete system replacement, our team is ready to help. Every service call is approached with diagnostics first — not assumptions — so you get clear answers and solutions that make sense.
From older homes near downtown Ann Arbor to newer builds across Washtenaw County, we design heating systems that perform properly, operate efficiently, and hold up through Michigan winters.
No pressure. No guesswork. Just professional furnace service done right.
