Buying a new HVAC system will require you to conduct some in-depth analysis to make sure you get the best available heating, ventilation and air conditioning for your home or business.

Make it easy on yourself and require the contractors to give you in-depth quotes. This will allow you to compare them apples to apples and understand any differences.

Itemize
You want an itemized list from each bidder. The list should include individual costs for the new unit, materials, permits, labor and installation. The details include the system’s Seasonal Energy Efficiency Ratio, the Energy Efficiency Ratio (EER), projected fuel efficiency and other data issued by the federal government.

Warranties
The contractor should spell out warranties and put in writing the charges for add-ons such as duct cleaning or upgrades to the thermostat.

How long?
Make sure you get a timeline, stating when the work will begin and when it will end. Otherwise a distracted contractor may leave your new system half-done.

With these factors printed in black and white, you can more easily see which contractor is making the offer that is best for your property and your budget.
