Back to School With HVAC Basics


Now is the time to get back some freedom as the kids head off to school once again. In the spirit of the back to school season, we want to spread some knowledge on a very underrated piece of equipment in our households. That piece of equipment is out HVAC systems.

Without our HVAC systems, we would not have any heat in the winter nor any cool air in the summer. Knowing how to maintain your HVAC, and know when to call for repairs can help you keep your system running at top-notch.

Below, we are going to give you the basics on your heating and air conditioning, how it works, and what to do in an emergency.

How Your HVAC Works

In general terms, an HVAC system works by either heating or cooling the air around you using the energy source that you choose (gas, oil, electric). There are three different types of HVAC systems that we are going to look at.

  • hvacsystemForced Air Systems- A forces air system works by using a network of ducts to circulate the cool or hot air throughout your home. With a furnace, the air is brought to the heating device and heated, it is then pushed through the ducts to where it’s needed. There are two separate duct systems; one for cool air and one for hot.
  • Gravity Systems- A gravity system works on the principle that hot air rises. So when you turn your thermostat up, the air is heated which then rises through the floor to heat your home. Gravity systems are always located on the lowest floor (usually the basement), and can not be used with an AC system.
  • Radiant Systems- Radiant systems, like gravity systems, cannot be used with an AC unit. Radiant systems use heat in the floor or walls to heat the room by “radiating” the heat. Though newer technology uses heated coils in the floor and walls to heat a space, a room radiator works on the same principle.

How To Maintain Your HVAC System


A properly working HVAC system is only going to benefit from regular maintenance. Maintenance should be performed by a professional annually, but there are a few things you can do yourself to make sure your HVAC performs properly.

  • Replace your air filters regularly.
  • Clear any debris away from outside AC units
  • Do a visual inspection to check for leaks, rust, and damage.
  • Check to make sure your pilot light is blue.

All of these things will help extend the life of your HVAC and help you reduce the number of repairs.

HVAC Repairs And How To Spot The Signs

With every HVAC system, there will come a time when you need repairs. These repairs can be minor, and they can be costly. The quicker you are able to spot signs of trouble, the quicker you can have a service technician on-site so the problem does not get worse.

Keep an eye out for these signs of repairs:

    I liked that you said that one reason to consider having air conditioning and heating units installed in your home is to make sure that your home will be a comfortable temperature during extreme weather. I have been thinking about having air conditioning and heating units installed in my home but I have been worried that it would cost a lot of money in repairs. I will be sure to hire a professional for routine maintenance in order to avoid major damage and repair costs.

    I think my air conditioning needs repair. It isn’t cooling my home as well anymore. There are some odd noises so I’ll get those looked at.

  3. Access Doors and Panels

    Maintenance is key indeed! Also, I would like to add how HVAC access panels help when it comes to repair and other fixtures, it provides convenient access to them. Thanks for the post!
