AC repair costs $150 to $650 on average, depending on the issue and the AC unit's age and warranty status. Major air conditioner repairs cost $650 to $2,500+ if the unit is out of warranty.
Common AC repairs and maintenance services include:
Air conditioning companies typically don't give free estimates for repairs. A service call for a heating and cooling system costs $75 to $200 to diagnose the problem.
Central heating and cooling replacement costs $5,000 to $11,000, including a new furnace and central AC unit. Total costs depend on the house size and the HVAC system size, type, SEER rating, and brand. Installing a new system with new ductwork costs $7,000 to $16,000 on average.
Installing optional features like an HVAC zoning system or new smart thermostat will increase your total upfront costs but may reduce energy costs in the long-term.
Heating and cooling companies typically offer these services:
Installing new central air conditioning increases a home's resale value by 2% to 10%, depending on your location. Central air is a good investment in warm climates but provides less value in regions with mild summer weather.
Replacing an existing central air system maintains but doesn't increase the home's value. However, upgrading to a more efficient system with a higher SEER rating may appeal to home buyers.
Look for these signs your HVAC system needs repairs or replacing:
Installing or replacing a central AC or HVAC system takes 1 to 2 days if using the existing ductwork or 3 to 5+ days if replacing old ductwork.
Contact an AC repair company immediately if your air conditioner is leaking refrigerant. Inhaling refrigerant gas can be fatal.
It's normal for an AC unit to leak a small amount of water due to condensation. Flush the drain line monthly with a 50/50 mix of distilled white vinegar and warm water to prevent blockages that could cause the drain pan to overflow.
