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:

  • hvacrepairOdd noises and smells.
  • Inconsistent heating or cooling.
  • Pilot light that is not blue.
  • Excess dust around your vents.
  • Your HVAC is 10 years or older.

    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!

    I would never have thought that a large amount of dust that exists near vents is a sign that my air system needs repairs. A couple of days ago, my sister was visiting my home and she mentioned to me that my vents were looking pretty dirty even though I just cleaned them a few days ago. It seems like I need to contact an HVAC technician and have them diagnose my air system for any potential issues.

    I like how you mentioned that part of maintaining your HVAC system is changing out the filters regularly. My sister is thinking about going to an HVAC replacement parts store because her home AC unit is making a weird noise and wants to try and have it repaired. It seems like a good investment to visit a reputable store that has high-quality and a variety of air cooling system parts.

    There are some things you can do to keep your AC system healthy for life of the unit. I like the helpful info you supply for your articles. Thanks for sharing a smart thought.

    Thanks for explaining how it’s important to schedule maintenance once a year to keep your heating system working in the best condition. In order to do this, it would probably be best to find a company that is located near your home and has a good reputation. You could probably talk to neighbors and others in your area to get their recommendations for companies and discuss the type of system they have in order to find one that is experienced with the kind of heating and cooling system you own.

    It’s fascinating to learn that, a gravity system works when hot air rises. My brother is fond of learning more about HVAC, that’s why he’s been telling me how he wanted to enroll in a school that provides courses for HVAC maintenance. I guess it’s best if we’ll start looking for a school that’ll teach him the different types of HVAC repairs that can do.

  9. Derek McDoogle

    I like how you suggest cleaning the outside AC unit to keep it in good condition. My neighbor told me that his HVAC system makes a loud noise when he turns it on. I will recommend him to hire a professional company to do the job for him.

    It’s interesting to know that having a forced-air system will be a sign that you need to call an HVAC contractor. My husband and I are thinking about how to keep our appliances in good shape, and we are looking for advice about what to do. I will let him know about the benefits of calling an HVAC contractor to help us.

    I like what you said about HVAC systems working to heat or cool the air around them. My sister has been telling me about how she wants to make sure that her home is properly cooled in the coming weeks. I’ll share this information with her so that she can look into her options for HVAC systems that can help her with this.
