Cooling & Air Conditioning FAQs

My AC is making a very loud humming noise. Can I fix my noisy air conditioner myself?

You should not try to fix your noisy air conditioner on your own! Unless you have professional knowledge of HVAC electrical system layouts and the proper meters to test all the working components of your AC, you are putting you and your air conditioner at a significant risk for harm.

My AC has ice on it—what do I do?

When your AC freezes up, either inside or at the outdoor unit, you have a problem. There are only two reasons for an AC system to freeze up—either there is low air flow or there is a low refrigerant charge.

How does an air conditioner work?

An air conditioner seems as if it cools your home’s air, but in reality an air conditioner makes your home less warm by removing heat from the indoor air and transferring that heat to the outdoor air.

Heat is extracted from the home by passing indoor air across a refrigerant coil in the indoor unit. Refrigerant lines then carry the heat to the outdoor unit, where it is released into the outside air. The cooling cycle continues until the indoor temperature reaches the thermostat setting.

What can I do about my air conditioner shutting off and on frequently?

If your air conditioner is shutting off and on frequently, this is most likely due to short cycling. That means that your system is turning off and on again too often and not allowing your home to reach the temperature you set on the thermostat. When your AC malfunctions this way, it’s not only frustrating, it’s inefficient too!

How does an air conditioner work?

You might assume an air conditioner cools the air in your home, but in reality, it works by removing heat and exhausting it to the exterior. Here’s your chance to learn more about how an AC works.

When you turn the thermostat to “cool,” the air conditioner kicks on as soon as the ambient temperature rises above the target temperature displayed on the thermostat. Then, it goes to work removing heat from the indoor air and exhausting it to the exterior.

An air conditioner works the same as a refrigerator or freezer, except that instead of removing heat from a small space until it reaches a frigid temperature, an AC keeps your entire house comfortable on hot summer days. Refrigerant is the key to refrigeration and air conditioning. By making a loop between the compressor, condenser, expansion valve, and evaporator coil, refrigerant absorbs heat and leaves cooled air to blow back into your home.

What does the AFUE rating on my furnace mean?

AFUE is short for “annual fuel utilization efficiency” and it is a rating expressed as a percentage of how much energy used by your gas or oil furnace goes directly toward heating your home. It accounts for heating lost or wasted. The higher the number, the more efficient your furnace is and the more money you should save on your monthly energy bills. Today, all new furnaces manufacture red must have an AFUE of at least 78 percent, and it’s not uncommon to see furnaces as high as 85 or 90.

While most furnaces with an AFUE higher than 90 will typically be more expensive that similar models with lower efficiency ratings, that cost can be made up from savings on monthly heating costs—a more energy-efficient furnace will require less fuel and energy to keep your home the same temperature as a less efficient model.

Why did my furnace shut off?

There are many reasons that your furnace may have shut off—including trouble with your motor, settings, pilot light, and more.

Why does my furnace smell musty?

If your furnace is spreading a musty, dusty, or dry smell throughout your home, you most likely have dust in your combustion chamber (where the fuel is burned). If you experience this, try changing your furnace filter. If the smell still lingers, schedule further inspection from a local and professional heating company.

Why does my furnace smell like gas?

The smell of gas might be coming from excess production of carbon monoxide. Since natural gas is odorless, manufacturers of gas furnaces add the “smell of gas” so that homeowners can detect a leak or dangerous amount of CO in their home. If you smell gas, leave your house immediately and call your local gas company or utility in case of a gas leak to avoid fire, explosion, or carbon monoxide poisoning. If you can, try to open windows to ventilate the air and avoid light matches or turning on lights.

Why does my furnace smell like rotten eggs?

Natural gas does not have a natural odor, so utility companies add a compound to give a smell. This allows homeowners to detect a gas leak more easily. If your house has the smell of rotten eggs (or sulfur), this is a sign of natural gas leak. If you know how to, shut off your gas supply line and then immediately call your gas company while evacuating your home.

With propane furnaces, smelling rotten eggs usually signals that you’re low on fuel.

Why does my furnace smell like burning material?

Sometimes electrical components of furnaces can fail, so if your furnace is emitted a burning smell (like an overheated iron), you most likely need furnace repairs. Scheduling annual inspections of your furnace before the heating season to pinpoint potential repairs can help prevent electrical failure and other more expensive repairs down the line.
