Problems with your heating or air conditioning?




Short for Heating, Ventilation, and Air Conditioning, the HVAC system is responsible for heating and cooling a building. Besides providing thermal comfort, it additionally influences indoor air quality at your home by providing ventilation and humidity control.

Did you know that an HVAC system loses about 5% of its original efficiency per year without regular maintenance? Moreover, without proper care, your HVAC unit may be performing as poorly as models that are years older! But there is good news: you can still recover most of that lost efficiency.

HVAC - Maintenance


The goal of preventative maintenance is to keep your HVAC system running at any moment with no surprise breakdowns while working at top efficiency. The same way your car needs regular maintenance, your HVAC needs it too. No matter how expensive your system is or the manufacturer’s promises, the heating and air conditioning systems are complex pieces of equipment subject to breakdowns. Repairs are needed every so often, but you can reduce their severeness and prevent them by keeping on top of annual maintenance.

Some benefits of regular maintenance are evident immediately, while others are noticeable in the long.

  • Lower energy bills. Even though your HVAC is heating or cooling your home without any apparent problems, your energy bills may show higher consumption. A neglected HVAC system gradually loses the level of efficiency it once had. Undoubtedly,¬†professional tuning can help your HVAC consume less energy.

  • Fewer repairs. Regular and thorough inspection of the whole system allows a technician to detect weak spots and replace malfunctioning parts in time before they cause more extensive damages. By preventing problems from developing to future repairs, annual maintenance pays off for itself.

  • Lower chances of a catastrophic breakdowns.¬†Of course, everyone wants an incident-free cooling and heating season. After all, it’s very inconvenient and uncomfortable when equipment breaks down in the middle of hot summer or freezing winter, right when you need your cooling or heating system most. However, the probability of this happening when you have regular maintenance every year are significantly decreased.

  • Longer equipment lifespan. Air conditioners, furnaces and other HVAC equipment function best when regularly serviced and cleaned. One malfunctioning part can cause a domino effect that can break down the entire system. Furthermore, regular maintenance prevents this from happening and adds years to your equipment’s lifespan.

  • Safer equipment operation. A failing HVAC system also can endanger your family. For example, a crack in the furnace’s heat exchanger can cause carbon monoxide gas to escape and poison the air. Also, electric wiring can develop a short circuit, which can be a serious fire hazard if ignored. Your family’s safety is yet another reason to schedule annual HVAC system maintenance.
