The answer to 'difference between HVAC repair and' is that HVAC repair refers to fixing specific issues with your heating, ventilation, and air conditioning system, while HVAC replacement involves completely replacing the entire HVAC system. HVAC repair is typically a more cost-effective solution when your system has a minor problem, while replacement is necessary when the system is old, inefficient, or has major issues that can't be easily repaired.
HVAC repair is usually faster and less disruptive than a full system replacement, but it may only provide a temporary fix if the underlying problem is not addressed. Replacement, on the other hand, provides a long-term solution by installing a brand new, energy-efficient HVAC system that can improve your home's comfort and lower your energy bills.
