DUBLIN – When getting an estimate for a new heating, cooling and ventilation system, make sure it addresses the big picture. First of all, the estimate should address all aspects of system operation, not just the HVAC unit itself. The estimate should also present alternative options to replacement, such as repairing the existing system (if viable). Furthermore, if your home contains asbestos or other risk factors, the estimate should address any related safety concerns.
In particular, any HVAC estimate should include information about the home’s air ducts. To ensure proper system performance, a new HVAC unit needs to be properly sized in accordance with the existing ductwork, which requires careful calculation on the part of the estimating contractor. In some cases, a contractor may recommend that the air ducts be replaced as well (depending on their size, age and condition), as leaky or damaged ductwork can substantially hamper system efficiency. Either way, a thorough estimate will ensure this crucial aspect of system installation doesn’t get overlooked.
