Not sure if you need a replacement or just repairs? Here are the telltale signs that it's time to invest in a new HVAC installation:
Your System is 10-15 Years Old
Even with regular maintenance, HVAC systems have a lifespan of 15-20 years. If your system is approaching or past this age, replacement is more cost-effective than continuing repairs.
Rising Energy Bills
Older systems lose efficiency over time, working harder and consuming more energy to maintain comfortable temperatures. A new, high-efficiency system can reduce energy costs by 20-40%.
Frequent Repairs
Are you calling for repairs multiple times per year? When repair costs exceed 50% of a new system's value, replacement makes better financial sense.
Uneven Heating or Cooling
If some rooms are too hot while others are freezing, your system may be undersized, failing, or improperly installed. A new system with proper sizing solves these comfort issues.
Strange Noises or Odors
Banging, grinding, or burning smells indicate serious problems. Rather than risk a catastrophic failure, invest in a reliable new system.
Uses R-22 Refrigerant (Freon)
R-22 refrigerant is being phased out and is increasingly expensive. Systems requiring R-22 should be replaced with modern, eco-friendly alternatives.
Indoor Air Quality Issues
Excessive dust, humidity problems, or persistent allergens may indicate your HVAC system isn't properly filtering or ventilating your home..
Don't wait for your HVAC system to fail. Whether you need emergency repairs, routine maintenance, or a free estimate on a new installation, Four Seasons Heating and Air Conditioning is here to help.
