what to know about your heating and cooling system

10 Things You Didn’t Know About Your HVAC

Air conditioning keeps us relaxed, keeps us healthy, comfortable, and cools us down. It’s even been shown to make us more productive!

It’s important that you’re knowledgeable about your heating and cooling system, no matter the time of year. You might think that you know all there is to know about your HVAC system, but there’s probably a few things you don’t know.

We’ll clue you in on some key info info…with a few fun facts sprinkled in, of course.

1. The Very First AC System Was Used in 1902

AC hasn’t been around forever, although people in the olden times probably wish it would’ve been! The very first air conditioner was put to use at a publishing company in New York. Due to the high humidity in the summertime, the ink in their books would dry unevenly. To prevent this, they installed the very first air conditioner (1).

2. Regularly Changing Your Air Filter Is a Must

Neglecting to regularly switch out your air filter will cause you trouble in the long run. In fact, clogged air filters are the leading cause of HVAC failures. You should be changing your air filter every month or two, especially if you own pets (2, 3).

3. Air Conditioners Are Getting Larger (Yes, Larger!)

If you’ve gotten an air conditioner replaced recently, you might’ve noticed that it’s larger than the one being tossed out. This is because energy regulations have demanded an increase in the minimum efficiency rating over the past few years, which calls for larger units (3).

4. People Used to Go to The Movies to Cool Off

In the 1930s, it wasn’t typical for homes or business to have AC. However, movie theaters did. This made the movies a very appealing attraction, especially in the summertime. It made for a cheap, fun way to stay cool (1).

5. Closing Your Vents Can Harm Your HVAC System

Sure, it’s a great way to cut down on your cooling bill costs, but closing your vents can actually put a strain on your HVAC system. Although it will cut off air flow to that particular room, it won’t re-direct the air. Instead, it causes stress to the system, and may even cause problems in the future. Bottom line: even though you’re saving money now, you might be costing yourself more with pricier issues in the future (1, 4).

6. Your HVAC Technician Should Be Licensed

Anyone installing or providing maintenance to your HVAC system should be a licensed technician. This means that this person has been professionally educated and trained to perform HVAC work. There are a variety of different licenses and certifications in the cooling and heating field, however each state has different conditions.

7. Your HVAC System Needs Regular Maintenance

Just like your car, your HVAC system needs consistent care to run efficiently. Regularly scheduling maintenance check-ups not only helps prevent future issues, but also improves energy efficiency…which saves you money the long run… score (7)!

8. “Summer Breaks” Began Due to a Lack of AC in Schools

It’s hard to focus in the heat! Back in the 1900s, most schools didn’t have air conditioning. This made for unbearably hot classrooms in the summertime, hence summer break. For the same reason, even some government buildings would shut down for a portion of the summer (1).

9. Air Conditioning Repairs Are Often Electrical

Most of the time, the root of an air conditioning issue is electric related. Blown capacitors, blown fuses, and tripped breakers are all common problems when it comes to AC repairs. When this happens, instead of trying to troubleshoot yourself, it’s best to have a professional take a look at your cooling system (3).

10. Your HVAC Will Show You the Signs Before It Tires Out

Your HVAC system (typically) won’t just quit on you out of nowhere; you’ll be able to see the signs. If you’re noticing that the thermostat temperature doesn’t match the temperature in the room, or the air coming out of the vent is the wrong temperature, there might be a problem.

Other signs, like inconsistent temperatures and unusual noises from the system, can also be trying to tell you something. If you notice something’s off, call for a service check-up (7).
