If you want to further improve the air quality in your home, the HVAC contractor can also advise on whether your home would do well with a humidifier or dehumidifier, as well as install them if you decide you do need one.
How Do They Fit in With the Larger Project?
Any full capacity home remodel will require you to visit or revisit your home’s air conditioning system, and an HVAC contractor will usually come in to do just that before the drywall goes up and after the main structure has been built. Even if you’re just looking to install a new system, an HVAC contractor will be there to help work out all the technical details. By considering your homes’ dimensions, the HVAC technician will determine the layout of your system as well as the type of heating and cooling system needed, and how much refrigerant will be required. HVAC contractors might also coordinate with electricians, mechanical contractors, and even plumbers to ensure that work is done correctly. For example, an HVAC contractor can collaborate with a plumber to ensure that a water boiler is correctly integrated into the HVAC.
A good HVAC contractor should be thorough, spending a lot of time evaluating a home, its insulation, and size before completing major work.
How Much Do HVAC Contractors Charge?
Some HVAC contractors will offer you free on-site estimates, but this is not always the case. Typically, they charge a minimum service call fee which can range from $75 to $200 per hour. How much an HVAC contractor costs will vary depending on your location, what size of home you live in, and what kind of work you need to be done. For routine maintenance and/or repairs, expect to pay from $75 to $150 per hour. However, more complex repairs can range anywhere from $300 to more than $2,000. For a complete HVAC replacement - meaning both furnace and AC unit - you can pay from $5,500 to nearly $12,000.
On average, cleaning your HVAC system can cost from $300 to $1,000, which figures to around $35 per air duct.
