Debunking 10 Common HVAC System Myths

HVAC air filterThere are plenty of myths surrounding the operation and maintenance of HVAC systems. The key to avoiding premature and expensive HVAC replacement cost in Brookhaven is to cut through these myths and find the truth. In this post, you’ll learn a little more about the 10 biggest myths that lead to confusion and expensive heating and cooling repairs.

1. You Never Have to Change the Air Filter

This isn’t true at all. Over time, dust and dirt build up in the filter and make it difficult for air to move through the unit. Let a dirty filter stay put for too long and you end up putting undue stress on the system that results in making a call for HVAC repair in Brookhaven sooner rather than later.

2. All Air Filters Are Easily Changed

Most air filters are easy to change. However, if you own a commercial unit or a residential unit that’s rather complex, calling for some professional help won’t hurt at all. In fact, it’s better to let the pros handle any sort of maintenance or repair job that you’re not too sure about.

3. Air Filter Changes Can Wait Until Maintenance Services

If you have your heating and cooling unit tuned-up once or twice a year, that’s great. However, most HVAC units need to have filter changes done every 30-90 days. Don’t wait until your bi-annual appointment to take care of this chore.

4. Turning the Thermostat Up or Down to the Extreme Changes the Temperature Faster

It’s important to let the heating and cooling unit have time to adjust to temperature changes. If it has gotten too warm or too cold in your home, turning the thermostat way up or way down isn’t doing your HVAC unit any favors. Take a gentler approach and adjust the temperature up or down a degree or two. In the meantime, put on a sweater or take a layer off to get comfortable while you wait.

5. You Shouldn’t Turn the A/C or Heat Off When You Leave the Building

Many people believe that doing this causes the unit to work harder when it’s turned back on and wastes energy. The truth is that anytime you turn the power off to your heating and cooling system, you’re conserving energy. Turning off the heat or air isn’t going to waste energy.

Thermostat6. It Doesn’t Matter Where the Thermostat Is Placed

This isn’t true. If a thermostat is located in an area of the house that is shadier or sunnier than most of the rooms, you’re going to experience poor heating or cooling. The thermostat should be in a location that tells the true story of how hot or cold an area actually is.

7. Close Air Vents to Save Money

Again, this is another myth. In actuality, shutting off vents puts a strain on heating and cooling units. So much so that if you have an older system, you could find yourself needing HVAC replacement in Brookhaven much sooner.

8. Preventive HVAC Maintenance in Brookhaven Isn’t Necessary

Forgoing routine maintenance to save money isn’t a good idea. All heating and cooling systems, regardless of age, benefit from regular tune-ups.

9. Service Agreements Aren’t Worth the Cost

Not true. In fact, most service agreements are budget-friendly and designed to catch small problems before they escalate. Often, technicians give discounts to their customers who have service agreements when repairs need to be made.

10. Finding a Good HVAC Company Is Impossible

There are plenty of great heating and cooling companies. If you’re looking for HVAC maintenance in Brookhaven, contact Cool Air Mechanical today!
