The answer to 'furnace repair vs' is that furnace repair and replacement are both options for homeowners with furnace issues, but the best choice depends on the specific situation. Furnace repair is generally the more cost-effective option if the issue is a relatively minor one, like a faulty thermostat or blower motor. However, if the furnace is old, inefficient, or has multiple major problems, replacement may be the better long-term solution despite the higher upfront cost.
Factors to consider include the age and condition of the furnace, the cost of repairs, and the potential energy savings and improved comfort from a new, more efficient model. It's best to have a qualified HVAC technician assess the situation and provide a recommendation based on your specific needs and budget.
