Not All HVAC Tune-Ups Are Equal

Research proves that a properly applied heating system tune-up will put money back into your pocket while simultaneously helping the environment; it’s as simple as that. How? By improving the system’s energy efficiency and performance, meaning greater comfort and reduced utility bills. Plus, you won’t have to run your furnace as often, leading to greater cost-savings and eco-friendliness.

However, you should be aware—some St. Louis HVAC companies offer low-cost, so-called “tune-ups” that, in reality, are glorified visual inspections designed to get the company’s foot in the door and up-sell an overpriced actual tune-up.

At Dunn Plumbing, Heating & Air Conditioning, LLC, we take great pride in providing high-quality furnace maintenance services in St. Louis and the surrounding areas, as well as furnace installations and repairs, all at a fair price. Never assume your heating system is working as efficiently as it could be until a Dunn Plumbing, Heating & Air Conditioning, LLC technician verifies it.
