7 HVAC System Myths

If you live in Central Maryland, you’ve undoubtedly heard about how implementing energy-efficient heating, cooling, and ventilation systems can help you save money on your utility bills. We’ve put some of the most commonly believed HVAC system myths to the test to ensure that you and your family live in the utmost comfort.

“HVAC equipment matters less than insulation and windows.”

As a general rule of thumb, HVAC equipment, insulation, and air sealing of the attic and basement are of equal significance. Without these components working together, the entire system suffers.

Even with a top-of-the-line heating and cooling system, leaks in the attic, basement, crawl space, or ductwork and outdated insulation could contribute to a performance that doesn’t meet your expectations. To learn more about Minnick’s insulation and sealing services, visit here.

“A new HVAC system will increase the value of my home as I’m getting ready to sell.”

Possibly, but this common misconception is often false. When discussing the sale of a house, a buyer may negotiate improvements as part of their offer. A newer HVAC system probably would not be mentioned in these terms, but if a home has an older unit, a buyer may request repairs in Laurel, MD. 

“A high-efficiency HVAC system will always lower my energy bills.”

High-efficiency HVAC systems alone don’t guarantee a reduction in energy costs. A well-insulated home with a properly sealed attic as well as a basement, crawl space, and ductwork will keep energy within the home and prevent cool or warm air circulated by the unit from escaping the house. 

As a result, your HVAC unit will function less frequently and consume less energy. If one of these factors is weak, you won’t reap the full benefits of a high-efficiency system. 

Geographic location, the season, and indoor temperature preference will inevitably cause variations in energy bills. If you’re wondering why your savings goals aren’t being achieved, call an expert like Minnick’s to book a comprehensive home energy audit.

“I don’t have to know about my HVAC equipment; that’s what my technician is for.”

Ignorance isn’t bliss when your HVAC repair bill comes. If your car breaks down unexpectedly, but you know nothing about cars, how would you explain the course of events to a mechanic? 

Becoming familiar with your system’s components will allow you to identify problems before they become difficult to repair. An annual tune-up of your indoor and outdoor unit is significantly more cost-effective than a repair bill. By having an annual tune-up completed every year, you’ll save money in the long run by taking preventative measures and keeping your HVAC system up to date.

“My system doesn’t require maintenance.”

You may have the preconceived notion that your HVAC unit doesn’t require maintenance. On the contrary, maintaining your HVAC system is necessary if you want to ensure the efficiency and longevity of your unit. 

Your car, major household appliances – even your health – all require maintenance, at the very least, for preventative purposes. An HVAC system is no different. A dirty unit will force the system to overcompensate for the accumulated debris and negatively impact energy efficiency. To have your HVAC unit serviced in Laurel, MD, click here

 “Keeping the temperature the same is more efficient.”

The smaller the difference between the outside temperature and the temperature set on your thermostat, the less energy your system will use to close the gap. Adjust your thermostat accordingly as temperatures fluctuate, and remember to adjust it if you won’t be home for a while. 

Some modern thermostats are programmable and, in the case of a smart thermostat, may offer advanced features such as temperature adjustment based on your movement throughout the home.

“Increasing energy efficiency doesn’t increase the value of my home.”

In recent years, energy-efficient features have become more appealing to home buyers as the benefits have become common knowledge. Some may be motivated to upgrade their equipment by a desire to live a more environmentally friendly lifestyle, but the capacity for savings resonates with everyone.
