Commonly Asked Questions By People:

What Is The Average Cost To Replace HVAC?

The price of the HVAC system will always depend on the size of the house. That’s right, the best heating, ventilation and AC companies in Fairfax VA will never provide you with an estimate of the HVAC replacement project over the phone because they’ve not seen the size of the house. Other than that, the brand and the rating of the HVAC unit will increase or decrease the cost of the project. What else? The length of the duct, the cost of labor, and add-ons will cost more too. 

On average the cost of HVAC replacement alone will cost a house owner around $4,800 - $9,300. But, if you want to replace the HVAC along with ductwork, the house owner will have to pay the Fairfax HVAC companies more than $6,800 - $12,000, and the time required for this process will be 5 working days. Whereas, if you want to replace the HVAC along with some add-ons, the process can take up to 7 working days and will burn a hole in your pocket, as it will cost $13,000 - $17,000 easily. 

So yes, before finally hiring one of the top local HVAC companies near you, you’ll have to make sure that the experts visit your house and inspect the existing HVAC system, the size of the house, and your budget. Only then the experts will be able to provide you with an estimate for the entire project. Keep in mind that an expert how provides you with an estimate without actually seeing the house will never proffer top-rated services.
