Why HVAC Preventative Maintenance Is Your Best Financial Decision
When it comes to your home’s heating and cooling systems, a vital truth remains constant: HVAC maintenance is crucial for the longevity of your unit. The choice is simple – “Invest in Preventative Maintenance Now… or Pay for Costly Repairs Later!”
Just as the memorable Fram oil filter commercial wisely advised drivers decades ago, our Unionville Heating & Air Conditioning technicians see the consequences of neglected maintenance every day across Markham, Stouffville, and surrounding communities.
The Real-World Cost of Skipping HVAC Preventative Maintenance
Our service records from 2024 reveal these compelling facts:
- Emergency repair calls cost our customers 2-3 times more than scheduled maintenance visits
- Systems with regular maintenance last 5-7 years longer on average (based on our 20+ years of service data)
- Well-maintained HVAC units operate up to 25% more efficiently, directly reducing monthly energy bills
- A dirty, unmaintained system increases energy consumption and drives up utility costs unnecessarily
- 84% of catastrophic system failures we responded to last year showed early warning signs that routine maintenance would have caught
“During last January’s cold snap, we received over 120 emergency calls in a single week,” explains Eric Ranchigoda, Service Manager at Unionville Heating. “Most of these expensive breakdowns could have been prevented with basic maintenance. By the time systems fail completely, simple adjustments become emergency replacements—often at double or triple the cost.”
