Deciding between repair and furnace replacement challenges many Calgary homeowners. Purcell Heating and Air Ltd applies the 50% rule: if repair costs exceed half the price of a new system, furnace replacement becomes the smarter investment. For Calgary systems under 15 years old with repair bills below $2,000, repairs often make sense. However, furnaces over 15 years old operating at reduced efficiency typically warrant replacement. Purcell Heating and Air Ltd technicians help Calgary customers evaluate factors like repair frequency—three major fixes in three years signals it's time for furnace replacement. Energy bills provide another clue; rising costs despite regular maintenance indicate declining efficiency that furnace replacement resolves immediately. Safety concerns like cracked heat exchangers make furnace replacement the only responsible choice, regardless of age. Purcell Heating and Air Ltd offers honest assessments, recommending repairs when appropriate but explaining long-term benefits of furnace replacement for aging Calgary systems. The company provides free estimates for both options, helping homeowners make informed decisions. With financing available and energy savings of 25-40%, furnace replacement often costs less over time than continuing repairs.
