Getting a Deal on a New AC: What to Look Out For

Share This:

If you think that it’s time to change the old HVAC system and get a new model, a sale is most definitely the best time to go forward with that decision. That being said, there are a few important factors which should be considered before making a purchase. After all, it is an essential appliance that should last you for anything between 8 and 15 years. You want to make sure the unit you buy is cost-effective and performs well if you’re going to own it for that long.

Quality Over Discount: Choose a Good Manufacturer

Try to select a renowned name in the HVAC business over manufacturers whose name you are hearing only for the first time. This is important to remember because new entrants they will often offer the biggest discounts during sale, but you will lose money in the long run in repairs, maintenance, and longevity. Trust established HVAC OEMs like Honeywell, Lennox, Trane, Trion and Rheem.


When you’re focused on getting the biggest discount on something expensive upfront, it’s easy to forget to consider how much you may have to pay in the long run. What you pay for the system upfront is not the only cost it incurs. Expenses like utility bills, air filters and maintenance charges add up over time and considering how long the system will last, you need to be particularly mindful about these costs.

If you choose an HVAC system from reputed manufacturers like Lennox, Trane, or Rheem for example, you can easily find aftermarket parts to lessen the cost of maintenance. For example, whenever you need air filters, this provider offers them at a discount compared to buying them from the OEM directly. In addition to saving money upfront, you will be saving money in the long run as well, since they offer heavy discounts on bulk orders.

Capacity and Space: They Must Match

In order for the furnace to effectively heat your home during winter, or the AC to cool it down in the middle of summer, the capacity (BTUs) of the system must be adequate for the space that it will be expected to heat/cool.

  • 25 British Thermal Units (BTUs) can cool/heat about a square foot of enclosed space
  • On multiplying the total square footage of your home with 25, we get the base BTU requirement
  • Any house or apartment with a ceiling higher than 8 feet should multiply the base BTU requirement by 1.25

While there are additional factors that impact performance (location of the furnace, expected temperature range, insulation of the home), we can use the classic BTU method to make a better purchase decision that’s more likely to be sufficient.
