temperature controllerAir conditioning systems are a godsend during Niagara Fall’s extreme summers and winters. For your health and comfort, it is important to ensure that your heating and cooling systems must are in good working condition during these extreme seasons.

Fortunately, there are warning signs when something is amiss. Here are some of the common signs of a malfunctioning unit.


If you notice a musty smell when your unit is working, it shows that there might be mold growing in the duct. Mold causes respiratory health problems and has a pungent smell.

On the other hand, if the air smells like something is burning; it shows that a part in the system has burnt out.

Liquid Leaks

If you find liquid around your heating or cooling system, it could be the refrigerant leaking out, a blockage in the drain pipe, or a leak in the heating unit of the furnace. For cases like this, it is best to contact a professional Niagara heating and air conditioning technician immediately. Mackay Heating & Cooling company recommends that when looking for a service provider, one should ask about the business’ license, if they offer warranties and if they are members of trade organizations.

Air gets too hot or too cold

If the air gets too cold or too hot or no air comes out of the vents at all, it could be caused by different problems. Your thermostat might not be working properly and causing the temperature to rise or go down. The air compressor may have failed, and so no air comes out, or the refrigerant may have gone down.

Cranking sounds

Most heating and cooling systems give out a humming sound while operating. However, if you get cranking or banging sound, there is likelihood that there is a problem that needs to be fixed by a professional.

Contact a professional technician once you get signs of a problem. It saves you from sudden breakdown and having to pay more to fix bigger damage. The technician may also find other areas that have a problem but had not been noticed.
