FAQs on Water Heater Services in St. Catharines
What Are the Signs My Water Heater Needs Repair?
Over time, your water heater may show signs of wear, such as inconsistent water temperature, unusual noises, or leaks. If you notice your water heater taking longer to heat water or see discolored water, it's time to contact Mr.Furnace. Our technicians will assess and resolve minor issues before they become major problems, ensuring the smooth operation of your system.
How Can I Improve the Energy Efficiency of My Water Heater?
Energy efficiency is key to reducing utility bills. Routine maintenance is essential for this improvement. Calling our team for regular check-ups can prevent energy-wasting leaks and optimize heater settings. Consider upgrading to a tankless water heater for increased efficiency, as they only heat water on demand and can significantly reduce costs.
How Often Should I Schedule Maintenance for My Water Heater?
We recommend scheduling maintenance at least once a year to keep your water heater in peak condition. Regular inspections by Mr.Furnace include checking for corrosion, sediment build-up, and ensuring safety mechanisms are working correctly. With proactive care, we ensure your water heater remains effective and extends its lifespan.
What Should I Do in a Water Heater Emergency?
In a water heater emergency, prioritize safety by turning off power and water supply to prevent further damage. Contact Mr.Furnace immediately. Our technicians are available 24/7 to provide fast and effective emergency repairs without additional charges, ensuring your comfort and safety are restored promptly.
Are There Any Local Rebates for Energy-Efficient Upgrades?
St. Catharines and the Ontario government occasionally offer rebates for energy-efficient home upgrades. These can significantly offset the cost of replacing an old water heater with a new, energy-efficient model. Our knowledgeable staff at Mr.Furnace can guide you on available rebate programs, helping you take advantage of these incentives.
Upgrading to an energy-efficient water heater not only provides potential cost savings through rebates but also reduces your household's carbon footprint, contributing positively to the environment. Our experts stay informed on the latest programs and can provide the necessary documentation to help streamline your rebate application process.

Is HVAC maintenance required?
Yes, HVAC maintenance is an essential task that is required for all HVAC units, regardless of the type of unit or its age. When your HVAC unit is not functioning correctly due to an undiagnosed problem, your indoor air quality and overall comfort of your home can significantly diminish as minor mechanical problems escalate into more severe and costly issues. As a result, you could risk breathing in dust, dirt, hair, debris, mould, mildew, and other airborne impurities that can end up causing preventable illnesses and allergies.
Furthermore, without consistent maintenance, your heating and cooling units can be more susceptible to complete breakdown. When maintained properly, HVAC units can last anywhere from 10 to 20 years. If not, they can last under 10 years, which will end up costing you more money on replacements. Additionally, regular maintenance helps support energy efficiency to help you save on your monthly utility bills.
With all that said, we understand that HVAC maintenance often takes a backseat when it comes to other responsibilities. This is why Mr.Furnace is happy to offer two maintenance protection plans that can help you have peace of mind knowing your HVAC system is functioning as optimally as possible throughout the year.
