Top 3 Reasons to Choose HVAC Maintenance and Repair in Cornwall Instead of Replacement

Replace your old or broken AC and furnace when necessary, but sometimes it makes more sense to keep your existing HVAC equipment running smoothly and efficiently with regular heating and air conditioning maintenance in Cornwall and timely repair from licensed HVAC technicians near you.

Choose HVAC repair and maintenance if:

1. Your HVAC system is under 10 years old and running well.

Most HVAC systems can be expected to last 10-20 years with regular use. With annual HVAC maintenance in Cornwall, you can keep it that way, ensuring your furnace and AC continue to operate smoothly and efficiently for many years to come.

2. Your HVAC unit shows common signs of wear and tear.

If your furnace or air conditioner is louder than normal, incoming air isn’t warm or cool enough, or the system keeps turning on and off, call for AC or furnace repair in Cornwall and our licensed technicians will investigate. Timely HVAC services in Cornwall can save you money by fixing small problems before they become big ones – and can even extend the life of your equipment.

Leaks or cracks in your gas furnace should be repaired immediately to protect you and your loved ones from potential carbon monoxide poisoning. Contact us immediately if you need emergency furnace repair in Cornwall.

3. Your equipment is under warranty.

Check your warranty whenever a furnace repair or air conditioning repair is needed to confirm how much parts and/or labour warranty coverage your HVAC system has, if any.

If the warranty on your AC unit, furnace, or heat pump has not yet expired, you will likely save more money by opting for furnace or AC repair and putting off a full replacement until necessary.


Frequently Asked Questions

Why isn’t my air conditioner or furnace working?

If your air conditioning unit isn’t working, it could be a refrigerant leak, a broken compressor or coil, or even a broken blower motor in your furnace or air handler preventing cooled air from making it to the rest of your home. If your furnace isn’t working, it could be due to a broken heat exchanger or blower motor, or even a dirty air filter in need or replacement.

A Home Depot Installer, experienced in heating repair and AC repair, can identify the problem and get your HVAC system back up and running – or advise other solutions.

How do I know if my AC needs to be replaced?

If you notice any of the following signs, you should consider replacing your A/C:

  • Your A/C is older than 10 years
  • Poor air flow even at maximum setting
  • A/C blows hot air due to low refrigerant or duct vent issues
  • Unpleasant odors resulting from mould or burning electrical components
  • Loud and noisy when in use
  • Faulty thermostat
  • Leaking refrigerant due to a blocked drain line. This is a serious issue that should be repaired promptly because refrigerant is poisonous.

My air conditioner is 7 years old and runs constantly. Can it be repaired?

HVAC repair should be the first option for a 7-year-old air conditioner or other HVAC system that is not functioning properly.

Most HVAC systems, whether it’s an air conditioner, gas furnace or heat pump, can be expected to last 10-20 years with regular HVAC service. Normally, a 7-year-old air conditioner would only be half-way through its product life cycle. In many cases, it may still be under warranty.

How often should I replace my HVAC system?

Depending on the frequency of use and maintenance, the Natural Resources of Canada recommends replacing your HVAC system every 10 – 15 years.

What is the average lifespan of a HVAC system?

On average, an air conditioner or heat pump should provide 10 – 15 years of service with proper maintenance.

A furnace or boiler for heating an entire home should provide 15 -20 years of service with regular maintenance.

How long do furnaces last on average?

Depending on the humidity level in your home, frequency of use and maintenance, the average gas furnace has a lifespan of 15 – 20 years.

Should I replace or repair my furnace?

The age of your furnace, frequency of use, humidity levels, and level of maintenance are the key factors that impact your furnace’s performance over time. Even the best, most energy efficient brands of furnaces, however, experience wear and tear with increased use.

Here are 3 signs that you need to replace or repair your furnace:

1. If your furnace is 15 years or older, consider replacing your furnace with a new energy-efficient model. Even if your warranty indicates a lifespan of 20 years, the frequency of repairs may increase over that time. Your furnace will also become increasingly less energy efficient and more costly to operate if it is older than 15 years and in need of repair.

2. If your existing furnace is 10 years or older, repairs and regular maintenance can extend the life of your furnace a few more years. Check the warranty to review your coverage before purchasing a new furnace.

3. If your furnace is less than 10 years old and you are experiencing issues, a professional HVAC repair service can likely resolve the issue for less than the cost of a new furnace.

How often should I service my HVAC system?

Scheduling annual or bi-annual HVAC service appointments is one of the best ways to protect your furnace, air conditioner or heat pump.

Booking regular HVAC maintenance appointments helps ensure your HVAC system runs smoothly, identify any problems before they get worse and reduce the likelihood you’ll need any costly HVAC repairs.

How can I avoid repairs to my HVAC system?

You can’t guarantee that your system will never need repairs, but changing out your air filters once every 3-6 months, ensuring that your outside unit is unobstructed, and keeping all vents indoors clear of blockage are good ways to ensure the long-term health of your HVAC unit.
