Choosing the right Air Conditioning System in Sudbury
When considering a new AC system for your home it is important to remember that not all air conditioners are created equal. No matter how big or small your space, there’s an air conditioning system that’s just right for you. Choosing the right AC will make it run more efficiently, keep you cool for longer and keep your budget in check.
Before you choose an AC unit, here are some important things to consider:
House Size and Location:
What direction is the house facing? The size of the space and the amount of sun you receive during the day are key when determining the unit size and power.
Insulation:
The insulation make-up of your home’s walls, ceilings, and windows will influence the size and power of the AC unit that you will need.
Energy Efficiency:
The best way to measure the energy efficiency of your Sudbury AC system is to check its seasonal energy efficiency ratio (SEER). The higher the SEER rating, the more energy you could save and the lower your operating costs could be.
There are many things to consider before buying (or renting) the right air conditioning system for your Sudbury home, and we are here to help you choose the best option.
Looking for a Heat Pump in Sudbury?
An electric heat pump is an air conditioner with the bonus that it can run in reverse and bring heat into your home on those cold spring and winter days, saving you from having to turn your furnace on until it’s frigid outside. It’s also an excellent choice for the environment and could help you reduce your carbon footprint! Be sure to check your local area for Government Rebates.

Frequently Asked Questions
SEER stands for Seasonal Energy Efficiency Ratio. This number is a way to measure an air conditioner’s energy efficiency. Most air conditioning units have a SEER rating between 13 and 21. A higher number is better, and may result in a lower utility bill.
No, but we do recommend having your AC inspected by a trained technician once a year. An annual tune-up could help keep your air conditioning system working efficiently and may identify small issues before they become a costly repair.
Ask your Home Comfort Advisor! We’ll let you know if there are any government rebates available for homeowners in Sudbury and will point you towards energy efficient models that may qualify.
