Adding heating and cooling to old homes is a challenge because the structures aren’t designed for modern HVAC systems. In this blog, HVAC and roofing contractor Hader discusses how heating and cooling can be added to old homes.
Air Conditioning
Old homes rely on boilers or fireplaces to provide heating, which means you aren’t likely to find ductwork in them. Unfortunately, installing new ducts may not be the most practical option, as this will require tearing down and rebuilding various parts of the house to accommodate them. There are, however, two ways to add an air conditioning system to an old home:
High-Velocity HVAC Systems — High-velocity HVAC systems feature efficient cooling routed through a compact duct system. Instead of standard metal ductwork, insulated fiberglass and aluminum tubes are routed through the drywall and roofing. To make up for the small duct size, air is pumped through the ducts at a higher velocity.
Ductless Mini-Split HVAC Systems — Ductless mini-split systems are mounted HVAC systems that are split in two. An outdoor enclosure contains the compressor unit, while a wall-mounted indoor enclosure houses the condenser and blower. Compared to a window-mounted air conditioner, a ductless mini-split system requires only a small hole through which to route the supply lines that run between the indoor and outdoor units. Cooling a large house may require several units.Heating
Heat pumps are basically reversible air conditioners, reversing the evaporation-condensation cycle so that warm air is generated instead of cool. A high-velocity HVAC system, therefore, can also function as the home’s heating system if you opt for a heat pump. While this can save you on installation and upkeep costs, you do have to stick to the prescribed maintenance routine. This is because in the event of an HVAC failure, both your heating and cooling systems will be taken out.
Alternatively, consider upgrading existing radiators if the boiler is still at peak efficiency. Certain parts may need to be upgraded or replaced, as well as insulation along the pipes. Modulating-condensing boilers heat water only when it’s needed (as opposed to continuously heating water in a tank), which can help you save on energy costs.Call Hader for Your Heating and Cooling Needs
