Number 1

How does my heating and air conditioning system move air throughout my home?

A fan draws indoor air in through vents called return grills, which are located throughout your home. The air travels through ducts that run to your system’s air handler, where it’s returned into the conditioned space through supply vents or registers in your wall, ceilings or floors.

Number 2

How often should I replace the filter?

There’s no one-size-fits-all answer. The frequency of filter changes is driven by how much your heating and air conditioning system operates, which is also driven by your individual climate. 

Start by checking the system’s filters at least once a month. Hold the used filter up to the light and compare it to a clean ‘spare’. When light is obscured by captured dust and dirt particles, the old filter should be changed. Keep a record for one year and then replace the filter on that basis.

At a minimum, it’s always a good idea to change filters at the start of the heating and cooling seasons and then in between, according to your needs. It’s also a good idea to have your heating and air system checked at the beginning of the heating and cooling seasons to ensure proper operation. 

Number 3

Why should I replace my working furnace or air conditioner?

Although your current furnace or air conditioner might be working, if it’s more than 12 years old, you should consider replacing it with a new high-efficiency system. A new heating and air conditioning system could save up to 50 percent on energy costs, and save you money in the long run on heating repairs. While these products save you money on your utility bills, they also offer a better degree of comfort within your home.

Number 4

We’re replacing our AC unit this season, what advice can you give me?

Replacing your system is one of the biggest financial decisions you will make. The reason for this is that the life expectancy of a system is around 12 years. When choosing a contractor, pick a company to install the unit based on quality and customer service, not solely on price. The name brand of the equipment is not as important as the installing contractor.

Another thing to keep in mind when replacing a system is that the duct system you’re connecting to is sealed tight with the proper amount of return air. With the new higher efficiency units, you also have to be careful that you replace your system with the right-sized unit, so you don't end up with a house that’s cool but has high humidity.

Do some homework, pick quality contractors, and find someone you trust and you’ll have a successful installation that will bring you years of comfort and the least amount of overall cost.

Number 5

What size system should I have installed?

The size of your system is paramount in your home. Too large and your system will short cycle and not control humidity correctly. Too small and it will run continuously. Please contact us for your free analysis today. We will be happy to configure just the right system for your needs.
