Common Questions
My furnace in Evanston keeps turning on and off frequently (short cycling). What can Landmark do?
Short cycling is a common issue in our climate, often caused by a dirty air filter, an oversized unit, or a faulty thermostat. Our experienced technicians will perform a thorough inspection of your HVAC system to diagnose the root cause. We can clean components, recalibrate or replace thermostats, and provide honest advice on whether a repair or a system adjustment is the most effective solution to restore consistent, efficient heating to your home.
Do you offer warranties on your plumbing and heating work?
Yes, we stand behind our work. Landmark Plumbing & Heating provides a one-year warranty on all services we perform. This warranty covers both parts and labor, giving Evanston homeowners confidence and protection after any repair, installation, or maintenance job, from a simple faucet fix to a complete furnace replacement.
What are the benefits of installing a tankless water heater?
Tankless water heaters, which we specialize in installing, provide on-demand hot water and can be more energy-efficient than traditional tank models—a plus for any household. They free up space and offer a continuous supply of hot water. Our team can assess your home's needs and plumbing to determine if a tankless system is a good fit for your Evanston home, ensuring proper installation for optimal performance.
