Commercial HVAC services can get confusing, so it’s no wonder that there are tons of misconceptions floating around the internet. With technology developing so quickly, environmental priorities shifting, and the rising demand for smaller, more efficient home systems, it can be hard to keep up with HVAC service trends when you’re not a professional.

In order to keep your home clean, comfortable, energy-efficient, and cost-effective, it’s important to know what guidelines you should follow when it comes to HVAC systems—and what myths you shouldn’t believe. 

This guide will debunk those myths and explain the 7 common misconceptions about HVAC services, from maintenance, to companies, to thermostats.

#1 Myth: If It Isn’t an Emergency, You Don’t Need a Professional

For most people, handling all HVAC maintenance alone is out of the question, but a lot of people only call in a professional when there’s something wrong. 

Even if you’re comfortable taking care of standard heating or air conditioning maintenance, like changing air filters and cleaning condenser coils for AC units and motors, scheduling regular professional checkups is a good idea.

Here’s why you should aim for yearly preventative maintenance:

  • Many AC unit warranties rely on regular servicing to remain valid
  • A trained technician will be able to identify small issues you didn’t know were there
  • Not keeping up with regular maintenance can lead to expensive emergency repairs
  • Your HVAC system will last longer with routine upkeep

#2 Myth: Air Filters Don’t Need to Be Changed Regularly

Changing air filters before they get too dirty is incredibly important—it keeps allergens and dust to a minimum, and using a clean air filter reduces your air conditioner’s energy consumption. 

This results in cost savings on your energy bill. 

A lot of people believe you only need to change your air filter once per year. While that’s the case in some homes, most tenants need to be changing their air filters much more often. 

It’s relatively easy to change yourself—and an inexpensive add-on to a regularly scheduled HVAC tune-up—so there’s no reason to put it off.

Here’s how often you should change your air filter:

  • If you have pets, live in a dusty or polluted area, or have allergies – Every 3 weeks, or once per month
  • If allergens aren’t a concern and you rarely use AC – Every 6 months, or once in the spring and once in the fall

 

An annual air filter change works in some instances. 

For example, if you don’t live in a large household, your home is in a more rural area, no one has allergies or asthma, and there’s only one pet and it doesn’t shed much… then an annual changing might be all you need. 

However, the best way to check if you need to change your air filter is simple: take a look at it every couple of weeks. If it looks dirty, or if you can’t see light through it when you hold it up to a light source, it’s time for a new one.

#3 Myth: Bigger HVAC Systems Are Better

Having an HVAC system that’s too big for your space will cause it to cycle on and off too frequently, which unfortunately does the following:

  • Shortens the unit’s lifespan
  • Makes it less energy-efficient and cost-efficient
  • Causes humidity—AC units have to run for a while before pulling moisture out of the air

#4 Myth: Big Companies Are More Trustworthy

Just because a big company offers commercial HVAC services doesn’t mean it’s a more reliable choice—they just have more money to spend on advertising so you’re more familiar with them. 

What matters isn’t how big or well-known a company is, but what they offer and how satisfied their customers are.

When searching for an HVAC company, consider these factors:

  • Credentials – State licensing and extra certification (such as NATE or HVAC Excellence)
  • Reputation – Better Business Bureau rating and customer reviews
  • Services – Look for specializations beyond heating and air conditioning repairs and installations, like energy-efficient upgrades and custom-built appliances
  • Cost – Ask for a price estimate and see if the company offers any rebates

 

#5 Myth: You Have to Pay for an HVAC Consultation 

Trustworthy companies will offer you a free HVAC consultation where you can explain and show your concerns to a technician—you should never pay for this step of the process.

#6 Myth: Your Thermostat’s Location Doesn’t Matter

Your thermostat needs to be placed away from direct sunlight, vents, windows, doors, and appliances like ovens that emit heat. 

You also don’t want to put it in a space that isn’t used often, like a spare room or hallway. In order to get the most accurate reading, you’ll want to put it in the center of your home, on an interior wall of a commonly used room.

#7 Myth: Setting a Thermostat to Extreme Temperatures Makes It Work Faster

Pressing a pedestrian push-to-walk button repeatedly won’t make a traffic light turn red any faster than clicking it once—the system is processing your request and can’t suddenly work harder. 

Thermostats are the same way. 

Raising and lowering the temperature to extremes in the hopes it’ll go into overdrive and heat up or cool down the space faster isn’t possible. It processes at one speed.
