The answer to 'which is better furnace repair or' is that furnace repair is generally better than furnace replacement, unless the furnace is very old or severely damaged. Furnace repair is typically more cost-effective and can extend the life of your existing furnace, while replacement can be a more significant investment.
When considering furnace repair, the key benefits are that it is usually faster, less disruptive, and more affordable than a full replacement. A skilled HVAC technician can often diagnose and fix common furnace issues, such as a malfunctioning thermostat, clogged air filters, or a faulty ignitor, without the need for a complete system overhaul. This allows you to get your heating system back up and running quickly and with minimal disruption to your home.
