    Our FAQ

    Do you have questions? We are here to help! Read our answer below. If you still have questions or can't find the answer you need, give us a call at (905) 367-0134 today!

    • How much does it cost to replace an air conditioner?

      Because no home is the same, we will need to book a free at-home assessment before we can fully answer this question. During this consultation, our technician will conduct a thorough inspection of your home before providing you with suggestions on how to optimize energy efficiency and possibly decrease installation costs.

      While we are unable to provide you with an exact number before visiting your home, we can give you a list of factors that contribute to the final installation cost so you can have a better idea about what to expect. These factors include:

      • The cost of labour
      • Whether you want to install a duct or ductless air conditioning unit
      • The quality of your air duct system
      • The British thermal units (BTUs) of your AC unit in comparison to your home’s square footage
      • The type, size, and brand of the air conditioning unit you choose
      • The variety of techniques our technicians must employ to install your new unit
      • The SEER rating of your new AC unit
      • The number of air conditioning units you want to install
      • The overall scope and size of the project

      To help with costs, Mr.Furnace also offers financing plans. We want to make the process of choosing and installing a new AC as simple as possible – trust our team to be honest, thorough, and focused on your needs!

    • How much do HVAC service calls cost?

      Much like when you are considering a new installation, all homes are different and costs can vary greatly depending on the scope of the issue. By scheduling a free initial estimate, our technicians can come to your home, inspect your equipment, and get to the bottom of the problem to provide you with an honest and accurate cost breakdown.

      There are some common factors, however, that can affect the overall cost. These include:

      • The cost of labour
      • The scope of maintenance or repair required
      • The size of your HVAC unit
      • The age and current condition of your home’s HVAC unit
      • The complexity of your home’s HVAC unit
      • The urgency of the problem at hand
      • Whether spare parts will be needed to fix a mechanical problem
      • The accessibility of your home’s HVAC unit

      Is there something wrong with your HVAC unit? If the answer is yes, call the team at Mr.Furnace today. We’ll promptly send a technician to your home to ensure you can get back to your regular schedule with as little disruption as possible.

    • How often should AC units be serviced?

      As a rule of thumb, homeowners should have their HVAC system serviced at least once a year. For heating units, we recommend booking an appointment in the early fall. This will ensure that we are able to catch and repair potential problems before the cold sets in. Additionally, regular service can maximize your home’s energy efficiency and provide you with peace of mind during the winter.

      For air conditioning units, we recommend scheduling a service in the early spring. This will provide you ample time to fix any required repairs to help ensure that your AC unit is prepared to function as the weather begins to heat up during the summer.

      Proactive HVAC services help homeowners diagnose potential problems before they become more costly and severe. Regular maintenance can also save your unit’s warranty for more expensive repairs that were otherwise not preventable.

      During a service visit, our team can also clean your air ducts to help ensure that accumulated dust, hair, dirt, and other debris does not circulate throughout your home. These particulates can affect your home’s energy efficiency and make you and your family vulnerable to persistent discomfort from allergies and cold-like systems.

    • What does HVAC service include?

      When you partner with Mr.Furnace, you can rest easier knowing that our technicians will work efficiently and thoroughly. Our services include:

      • Checking refrigerant levels
      • Finding leaks in your HVAC system
      • Applying lubricant to any mechanical components to ensure they function correctly
      • Thoroughly inspecting your HVAC unit to ensure all parts are functioning correctly
      • Diagnosing potential problems before they become more severe and costly
      • Ensuring safety controls are functioning correctly
      • Drain cleaning to remove any clogs
      • Cleaning or replacing your HVAC unit’s air filter to remove built-up dirt, dust, hair, and other debris that may be preventing the unit from functioning correctly
      • Checking your home’s thermostat to ensure all settings are functioning correctly and the temperature reading is accurate
      • Cleaning the indoor and outdoor HVAC compartments of split systems to remove dirt, dust, and other debris
      • Inspecting all electrical components
      • Cleaning ductwork
      • Inspecting any odors or sounds that may indicate there is something wrong with your HVAC unit

      We know that it can be challenging to determine when there is something wrong until it is too late. However, contacting us as soon as possible if you notice any of the following signs can help prevent bigger issues:

      • There are odd odours or sounds coming from your HVAC unit
      • You notice an increase in your monthly energy bill without a corresponding uptick in usage
      • You find it difficult to heat or cool your home evenly
      • Your thermostat will not turn on or the reading is inaccurate
      • You can’t remember the last time you serviced your HVAC unit
      • You and your family are experiencing unexplained allergy symptoms
      • There is poor airflow coming through your vents in each room
      • You discover a pest infestation in your air ducts
      • You notice the presence of mould and mildew in and around your HVAC unit

      Do any of these signs seem familiar to you? If the answer is yes, then it’s time to call Mr.Furnace. Our professionals take pride in our prompt response and thorough approach to keep you comfortable year-round.

    • 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.

      Our Just Right! Protection Plan provides:

      • A 21-point inspection of your HVAC unit
      • A guaranteed appointment within 24 hours of your call
      • An annual efficiency inspection and tune-up that includes a comprehensive safety check
      • A discounted diagnostic fee
      • 20% off all repairs that are not covered under warranty
      • 20% off indoor air quality products and duct cleaning
      • 100% guarantee on all repairs within one year

      We also offer our Just Right! Protection Plan+, which includes:

      • A 21-point inspection of your HVAC unit
      • Front-of-the-line HVAC services within a 24-hour period of you calling one of our team members
      • 10% off the purchase of parts and mechanisms should there be something wrong with your HVAC unit
      • 10% diagnostic fees
      • 10% off all indoor air quality products and duct cleaning services
