CM Heating - Choosing the Right AC Unit for Your Home: Factors to Consider

If you’re a homeowner, you will likely need a new AC unit for your home at some point.  Choosing a new air conditioning unit isn’t easy, but with the direction from the experts at CM Heating, you can upgrade your home with a system that fits your home perfectly. As Bellingham‘s AC replacement expert, we are here to share the top factors to consider as you make your purchasing decisions.

How to Choose a New AC Unit

Air conditioning units are expensive and are often seen as an investment that homeowners must make to achieve the desired temperatures in their homes. Choosing the right air conditioning unit for your home can make a big difference on the comfort of your home and your energy bill. Choosing the correct AC unit for your home is essential for several reasons:

  • Maximum efficiency
  • Comfort
  • Indoor air quality concerns
  • Longevity of the unit
  • Energy savings

All of these reasons are worth trying to choose the right unit. Below are some key factors a homeowner must consider when looking at all the available options for their heating and cooling needs.


One of the most important considerations when choosing your air conditioning unit is the size required to cool and heat your home efficiently. The AC unit size should be appropriate for the size of your home. If it is too small, it will not be able to cool the home adequately. On the other hand, a unit that is too large will waste energy and may not remove humidity effectively. An inappropriately sized unit tends to wear out quickly as it will struggle to serve the home adequately. A Bellingham AC replacement tech will enure the proper size unit. 


The seasonal energy efficiency ratio, or SEER, rates the efficiency of an air conditioning unit. The higher the SEER rating, the higher the efficiency of the unit. In the long run, homeowners who want to save money on energy costs will be especially interested in choosing a unit with the highest SEER rating. Such units are also better for the environment.

By the way, have you heard of the tax credits being made available through the Inflation Reduction Act of 2022? Read our blog for more information about how you can take advantage of the tax credits being offered to those who upgrade their HVAC products to high-tier efficiency units.


Not every air conditioning unit is the same. Currently, the most common types of HVAC units on the market include heat pumps, central air conditioners, or ductless multi-split units. The type of unit you choose will depend upon your budget, what system your home is set up for, and your household’s needs. Each type of unit comes with its own features, price points, and advantages that you will want to discuss with a Bellingham AC replacement technician. 

Noise Level

Are you okay with some noise from your AC, or do you not want to hear it at all? The answer to this question will help you understand the type of unit that will suit your home best. Heat pumps are primarily underground and, as such, are the quietest. 

An AC unit in good, maintained condition shouldn’t be loud, regardless of its type. We recommend checking its compressor for defects or malfunctions if the AC seems noisy. 

Brand and Reliability

Another key consideration for choosing the proper AC for your home is the brand of the unit. There are many brands to choose from, but we recommend keeping the following manufacturers at the top of your list: 

  • Carrier
  • Daikin
  • Mitsubishi Electric 
  • Rheem
