Frequently Asked Questions

How Are Furnace Filters Rated?

Furnace filters are typically rated using the minimum efficiency reporting value (MERV). A higher MERV rating indicates that the filter can remove more airborne particles than a filter with a lower rating. While MERV is the industry-standard rating system for HVAC systems, other rating systems exist. The filter performance rating (FPR) and micro-particle performance rating (MPR) were introduced by Home Depot and 3M respectively just to differentiate their products. However, the ratings apply to the same filters that you can use in your furnace.

Can My Furnace Catch On Fire or Explode?

With a furnace comes the risk that your unit could catch fire and explode. Your furnace involves a complex combination of natural gas or heating oil, electricity, water, metal parts, steam, and other crucial components. If you have a gas furnace, for example, and too much natural gas is leaked into the air, it quickly builds up. And since natural gas is highly volatile, it can easily explode and cause a fire. The best way to prevent a furnace fire or explosion is to schedule regular maintenance and ensure your furnace is in good repair.

Why Does My Air Conditioner Smell Like Vinegar or Gas?

Your AC might emit a wide range of smells depending on its condition. When the air coming from your unit smells like vinegar, the problem could be:
  • A dirty filter
  • An electric motor emitting ozone
  • A clogged condensate pan or drain line
  • Mold in the ductwork
  • Too much condensation
If your air conditioner smells like gas or rotten eggs, there’s a big chance you have a natural gas leak in your house. Once you notice a sulfur-like or rotten egg odor, turn off your gas supply, open the windows, evacuate your home, and call your gas company immediately.

Furnace vs. Heat Pump: Which One Is Right for My House?

A furnace and heat pump take different approaches to heating your home, but you need to consider each system carefully before choosing which one is right for your home. When choosing between the two, it really depends on your priorities. If comfort is most important, a furnace will keep you warm and cozy through the harshest winters. If efficiency is your top concern, the heat pump is the clear winner. When comparing costs, furnaces are cheaper to buy and install. However, a heat pump can offer better operational efficiency and long-term savings in areas with milder temperatures. Our experts can help you make the right choice.

How to Decide Between Ductless Mini-Splits and Central Air Conditioners?

When it comes to the HVAC industry, there’s rarely a one-size-fits-all solution. Deciding between ductless systems and central air conditioners depends on your preference, as well as your particular comfort goals and budget. Each system has its pros and cons, so you’ll want to weigh your options and choose the most suitable system for your property. That said, some scenarios will work best with both options, with the central AC system servicing most of the property while a ductless unit services an extension or room that lacks ductwork or is challenging to heat and cool.
