HVAC System
October 9, 2020

Everyone has HVAC systems in their homes and offices. While HVAC systems make homes livable and bring a tremendous amount of relief, like all things, they also require maintenance. This is why it’s very important to be aware of when your systems are in need of HVAC repair.

What is HVAC?

Heating, ventilation, and/or air-conditioning systems are any number of things:

  • Air-conditioners
  • Air purifier
  • Dishwashers
  • Freezers
  • Furnaces
  • Induction cookers
  • Laundry dryers
  • Microwave ovens
  • Refrigerators
  • Washing machines
  • Water heaters

Sometimes, these appliances can have glitches, especially when there are power surges during extreme weather conditions. Other times, malfunction can occur from accidents or neglect. Even the best air purifier can suddenly stop working properly out of nowhere.

When Is Time to Call a Professional?

Ideally, your HVAC systems should be checked annually. 

A breaking AC is pretty easy to spot – air isn’t as cold as it usually is, the compressor won’t engage, and the like. A lot of devices actually have warning signs or error messages, or they simply stop working. Still, there are some that don’t tell you something’s wrong until it’s too late.

Here are some signs that it’s time to head to a repair center or make an emergency service call for your HVAC unit:

  • Inadequate or weak power – This is especially applicable for heating or cooling units! Sometimes this could be something small, like a dirty and therefore clogged air filter. That much won’t need intervention, but it’s not always that easy. There could very well be an issue in the wiring, which could be a fire hazard.
  • Nasty smells – While it seems obvious that a burning smell is not good, there are other odours to look out for. Short-circuits in the system will present themselves with an electrical smell. A musty smell coming from vents could already mean a buildup of mildew or mold. 
  • Odd noises – Just like cars or even airplanes, any irregular noises are signs of a bigger issue. While it is possible for it to be a minor issue, like a loose, forgotten toy in a batch of laundry placed in the washing machine, it could be something far more dangerous.
  • Uncomfortable change in temperature – Air-conditioner, electric fans, and heater working, yet it’s very hot or incredibly cold? Something is definitely wrong. Fully functional HVAC systems don’t just have an extreme drop or rise in the temperature they provide.

Conclusion

HVAC systems require regular upkeep, and most of the time, they require an HVAC professional’s expertise. By knowing the signs that signal your HVAC system needs repair or maintenance, you’ll be able to address the issue immediately with the help of an HVAC expert, preventing further damage and minimizing risks.

When you bring your appliance in for basic maintenance, the technician will generally have a checklist of adjustments, areas to clean, inspections and tests depending on the season. Diligent, regular maintenance can prevent damage, but there will always be room for accidents or malfunction. Should that happen, it’s best to get professionals to assist right away.
