Grandy Plumbing & HVAC Company | T M Johnson Bros Since 1964

Aging HVAC equipment is common in our area. We start with a thorough inspection of your entire system, including combustion analysis and airflow testing, to pinpoint inefficiencies or wear. Often, a professional tune-up or a targeted repair can restore performance. If replacement is the better long-term value, we'll explain your options, from high-efficiency furnaces to heat pumps, focusing on solutions that improve comfort and reduce operating costs for your home.

We provide comprehensive plumbing inspections and maintenance to help prevent emergencies. This includes checking for leaks, assessing water pressure, inspecting water heaters, and ensuring drains are clear. As a Master Plumber-led company, we focus on identifying small issues before they become major problems, helping you maintain a reliable and efficient plumbing system throughout your home.

Over time, dust, allergens, and debris accumulate in ductwork, which can reduce your HVAC system's efficiency and impact indoor air quality. Our duct cleaning service helps your system move air more freely, which can improve heating and cooling performance and contribute to a cleaner home environment. It's a valuable part of overall system maintenance, especially after renovations or for households with allergy concerns.
