Just like roof, siding and window replacements, HVAC replacement costs vary depending on many factors. If you’re wondering how HVAC contractors come up with their estimates, read on as air conditioning repair company AAA Air Conditioning, Inc. shares a look at the factors that affect HVAC replacement costs.
The Local Climate
Heating and cooling requirements vary depending on where you are in the country. Homes here in the South require high-capacity air conditioners to allow enough headroom while providing sufficient cooling. Comparatively, a similarly-built house located up north would require a medium-capacity air conditioner paired with a high-capacity heating system.
The ductwork delivers conditioned air throughout your home and is as much a part of the HVAC system as the air conditioner, the blowers and the registers. Ductwork may have minimal moving parts, but they can develop problems such as leaks at the joints. If you’ve been keeping up with your air conditioning and heating repair contractor with regards to ductwork cleaning—which should be done every three to five years—chances are, your ductwork won’t require replacement.
Air conditioner performance depends on how well insulated your home is, due to a phenomenon known as thermal transfer. On hot days, a house with poor insulation will absorb heat from the sun and air, which can result in higher indoor cooling requirements, therefore a more expensive air conditioning unit may be required. On the other hand, a house with a properly-insulated attic, exterior walls and fenestrations (entry doors, skylights and windows) won’t need as much cooling. This gives the homeowner a better selection of air conditioners to choose from.
HVAC Make & Model
Prices vary between air conditioner makes and models, which affects the HVAC replacement cost. Don’t make the mistake of simply choosing the most affordable model: take the time to compare specifications such as the Seasonal Energy Efficiency Ratio (SEER) rating, ENERGY STAR® certification and expected lifespans. Some models might cost slightly more, but may also have extended warranties, rebates from the manufacturer or updated technology.
