HVAC systems are complicated so it’s no wonder why misinformation about them is so common. Still, these prevalent myths are the reason why many preventable issues turn into serious damage or expensive repairs for many households. With so much information about HVAC maintenance out there it can be hard to differentiate fact from myth but today we’re here to help.
We’re going to dispel some popular HVAC myths and talk about the truth behind them.
Duct tape for ducts
Despite its misleading name, duct tape isn't used for ducts at all. While duct tape remains a useful tool in many homes, it cannot withstand the extreme temperatures that air ducts can reach. This makes it ineffective when used on ductwork as well as a safety code violation because of its potential to be a fire risk. However, there are special foil-backed adhesive tapes that can be used to repair minor leaks and seams in your home's air ducts.
Lower or higher means faster
Many people are under the impression that if you turn your thermostat down lower or higher than you want it, then your home will heat up or cool down faster. Unfortunately, this just isn’t true. By doing this you won't be making your system work any harder or more efficiently, you will only be making your system run for longer. Typically, you will spend more on energy costs and put unnecessary stress on your system but your home will not reach the desired temperature faster.
If it aint broke don’t fix it
Many think that if their HVAC seems to be operating normally then it must not need maintenance, but this couldn't be further from the truth. Your HVAC system is full of delicate and complicated components that require regular appointments with a technician to maintain. These appointments can keep your system working at its best and help it reach its expected lifespan.
Of course, if you’ve noticed a significant change in your systems behavior or performance, it may be an indication that you’ve waited too long between appointments with your HVAC technician.
Higher rated air filters are better
The MERV (Minimum Efficiency Reporting Values) rating system is the trusted method of measuring the efficiency and level filtration of air filters. Although this rating system is very helpful it has misled many into thinking the higher the rating is the better the filter will work, however this isn't quite true. Higher rated filters are denser and will trap smaller particles but it will also restrict the airflow more and make your system work harder to circulate air. Filters with a rating between 5-8 are enough to maintain a comfortable environment for most homes while ratings 9 or higher are usually only necessary for households with respiratory issues or allergies. As higher rated filters cause more stress on the system, it’s best to avoid them unless they are necessary.
