Determining whether you need an HVAC repair or replacement depends on several factors. If your system is relatively new and experiencing minor issues, a repair may suffice, saving you money. However, if your HVAC is over a decade old and frequently breaking down, a replacement might be more cost-effective in the long run, as older units tend to become inefficient and costly to maintain. Consider the repair costs and the frequency of breakdowns compared to the potential energy savings and improved performance of a new system. Consulting a licensed HVAC professional is essential to assess the system's condition and provide expert advice tailored to your specific needs.
