With that being said, we are able to provide you with a list of considerations your professional technician will factor into your service cost.

How often should HVAC units be serviced?
As a rule of thumb, homeowners in St. Catharines should have their HVAC system installed in their homes serviced at least once a year. For all heating units, we recommend booking an appointment with Mr. Furnace Heating and Air Conditioning in the early Fall. This will ensure that we are able to catch potential problems with your unit and repair them before the weather begins to get colder in the area. In addition, it will also provide you with peace of mind knowing that your heating unit is ready to work optimally so you can maximize your home’s energy efficiency during the winter.
On the other hand, homeowners who also have an air conditioning unit in their home will want to book a service appointment with our professional HVAC contractors in St Catharines in the early Spring. Again, this is going to provide you ample time to fix any repairs that may be required following a diagnosis that we discover while ensuring that your air conditioning unit is prepared to function as optimally as possible as the weather begins to heat up during the summer.
By being proactive with your HVAC services in St Catharines, homeowners can diagnose potential problems with their units should they arise before they become more costly and severe. At the same time, regular maintenance on your HVAC unit can also save your unit’s warranty for more expensive repairs that were otherwise not preventable.
Furthermore, your home’s air ducts, which are also a part of your overall HVAC system, will also need cleaning. Beyond heating and cooling, your HVAC system is also responsible for circulating the air throughout your home. However, over time your air ducts can collect dust, hair, dirt, and other debris that can not only affect your home’s energy efficiency but it can also make you and your family vulnerable to allergy and cold-like systems that are difficult to overcome.
Therefore, when servicing your HVAC unit with Mr. Furnace Heating and Air Conditioning, you may also wish to book a cleaning for your air ducts. That way, you can rest assured knowing that your HVAC unit and air ducts are working optimally while providing you with the convenience and ease of making your home a clean and comfortable living environment for you and your family.

Is HVAC maintenance required?
Yes, HVAC maintenance is an essential task that is required for all HVAC units, regardless of the type of unit you have installed in your home and its age. HVAC systems are a crucial feature that allows homeowners to heat, cool, and ventilate the air throughout the house, regardless of the time of year and what the weather is like outside. Therefore, when your HVAC unit is not functioning correctly due to an undiagnosed problem, your indoor air quality and overall comfort of your home can diminish significantly. As a result, you can put you and your family at risk of breathing in dust, dirt, hair, debris, mold, mildew, and other airborne impurities that can end up causing explained illnesses and allergies that could otherwise be preventable.
On the other hand, when homeowners do not commit to regular HVAC maintenance at least once a year, depending on the HVAC unit they have installed in their home, they also run the risk of having minor problems developing into more severe and costly issues that again, could have otherwise been preventable should they have been discovered earlier.
Furthermore, without consistent maintenance on your HVAC unit, homeowners in St. Catharines can also make their home’s heating and cooling units vulnerable to complete breakage before their approximate lifespan. Generally speaking, HVAC units can last anywhere from 10 to 20 years when maintained properly. However, if not, they can last under 10 years, which will end up costing you more money in the long run.
In addition, HVAC units are not functioning to their fullest efficiency. Therefore, you may be spending more money on your monthly heating and cooling bill than you should be. Ultimately, being proactive in your HVAC maintenance is key to catching problems early, extending your unit’s lifespan, and saving money on repairs and monthly bills.
With that said, we understand that HVAC maintenance often takes a backseat when it comes to other responsibilities you have in your busy schedules. This is why Mr. Furnace Heating and Air Conditioning is happy to offer two maintenance protection plans that can help you have peace of mind throughout the year, knowing your HVAC system is functioning as optimally as possible in your home.

What Homeowners Say About Mr. Furnace’s HVAC Services





“I have had the best quality service, maintenance and assurance of safety and performance of the furnace and humidifier unit! Matt and others have been professional and explained the issues of concern. This was a scheduled annual maintenance and some problems needed tending to proactively rather than waiting for the system to break down. I am so glad I joined the monthly program. A superb company and team!“





“Starting with Salesperson Mike, and ending with tech installation team, Gareth and Lucas, the entire project was seamless. No pressure sale with genuine care and expert advice, offering next day install at a fair price. Promptly on Sunday morning, Gareth and Lucas showed up, and didn’t stop until the install was complete. Friendly, knowledgeable, considerate and professional, all attributes indicative of Mr. Furnace. System works great and I am extremely pleased with the service, price and overall experience.“
