Heating and Air Conditioning questions, answered by experts

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.
