How Often Should You Change Your Air Filters?

One of the most common questions I get from new home owners is, “How often should we change our air filter?” This is a very good question!  My response is to check it monthly and if it appears to be dirty then replace it.  If not then check it again next month.  At minimum an air filter should be changed every three months.

Air filters appear clogged with dirt and hair when dirty, like the image on the left.

What can happen if you don’t replace it?

A whole lot! A clogged air filter prevents air from moving through your air conditioning system.  This makes your system work harder than it has to.  This means that it costs more on your electric bill each month.  Now if the high bills don’t get you down then the next thing to happen is that the system will ice over and will eventually freeze up the indoor evaporator coil.  When this happens the unit will have decreased cooling capacity and it will often cause a water leak. Then it will be time to call an air conditioning repair company.

It’s a simple thing to do, change the air filter.  Mark your calendar and do it.  It will save you money all the way around!


Amana’s Inverter Technology

The Amana brand AVXC20 High-Efficiency Air Conditioner advantage
Up to 24.5 Seer
Amana brand’s legacy of energy efficient cooling systems continues with variable-speed Inverter technology compressors.

Simply stated, an Inverter technology compressor functions much like a dimmer switch to a light bulb.

With an Inverter technology compressor the power and speed levels are adjusted automatically to use the least amount of energy required to maintain the temperature you have selected on the thermostat. When more power or speed is needed the Inverter technology increases the compressor’s performance. After the correct temperature is achieved, the Inverter technology automatically calculates the lowest amount of energy required to maintain your indoor comfort. The result is lower utility bills compared to single speed compressors and more constant indoor comfort because the compressor is not operating a full capacity every time it is activated.

Heating Safety Tips

Did you know that the National Fire Protection Association states that heating equipment is a leading cause of home fire deaths? Half of home heating equipment fires are reported during the months of December, January, and February.

Here are a few steps that can prevent most heating-related fires from happening.

  • Keep all combustibles at least three feet away from heating equipment, like the furnace, fireplace, wood stove, or portable space heater.
  • Have a three-foot “kid-free zone” around open fires and space heaters.
  • Don’t ever use your oven to heat your home.
  • Always hire a qualified professional install stationary space heating equipment, water heaters or central heating equipment according to the local city codes and manufacturer’s instructions.
  • Have heating equipment and chimneys cleaned and inspected every year by a qualified service professional.
  • Be sure to turn portable heaters off when leaving the room or going to bed.
  • Always use the right kind of fuel, specified by the manufacturer, for fuel burning space heaters.
  • Be sure to store the fuel away from the heater itself.
  • Be sure to use a fireplace screen in front of your fireplace.
  • Test smoke alarms monthly.
  • Change smoke detector batteries each spring and fall.

Be Safe This Winter!

Carbon Monoxide Poisoning and Home Heating Systems

Flu-like Symptoms May Indicate a Hazardous Carbon Monoxide Leak in Your Gas Heating

Carbon Monoxide Poisoning can be an increased health risk during the cold winter months when people are more likely to use space heaters, water heaters, gas furnaces, wood and gas fireplaces and stoves to keep warm in their homes. Exposure to carbon monoxide, which is odorless, colorless and tasteless, can cause carbon monoxide poisoning that presents with flu-like symptoms. These symptoms may include fatigue, headaches, dizziness, confusion or disorientation, and vomiting. Extended exposure to carbon monoxide can be fatal, so reduce your risks for carbon monoxide poisoning by getting your home heating system inspected and maintained regularly.

According to data from the American Association of Poison Control Centers, exposure to carbon monoxide resulted in 47 U.S. carbon monoxide poisoning deaths in 2008. Because this data was collected from those deaths reported directly to the poison control centers, the true fatality rates from carbon monoxide poisoning nationwide may be significantly higher. In order to reduce your risk for carbon monoxide poisoning, it is important to get the flue pipe of your home heating system inspected for restrictions or leaks, as a leaking flue pipe can be the source of a carbon monoxide leak in your home.

A basic heating system tune-up service can ensure your gas heating is working safely and efficiently. A heating maintenance system technician will fully inspect the flue pipe of your home heating system and make any adjustments or repairs necessary to prevent leaks that can lead to carbon monoxide poisoning. Additionally, technicians will check all controls of the heating system to assess proper and safe operation, from the start of the heating cycle to the end, to ensure it is shutting off properly. A complete inspection of all gas connections, gas pressure, burner combustion and the heat exchanger will further ensure against carbon monoxide poisoning and potential fire hazards.

When getting a new home heating system installed, be sure to hire a fully-licensed and experienced heating system installation expert to avoid the potential hazard of carbon monoxide poisoning from a poorly installed unit. In addition to scheduling regular maintenance inspections of your home heating system, fireplace, chimney, flues and wood stoves before each cold season, it is recommended that you follow these tips to avoid carbon monoxide poisoning in and around your home:

  • Don’t use charcoal or kerosene in the fireplace, and never use a charcoal or gas grill inside a house, enclosed porch, garage or tent. Don’t use a gas stove or oven to heat the house.
  • When using your fireplace to burn wood or gas logs, be sure the flue is open and the chimney isn’t blocked, and don’t use these at all unless you have a carbon monoxide detector installed in your home.
  • Install a carbon monoxide detector with a good battery back-up system in your home. Larger homes will require more than one detector to guard against carbon monoxide poisoning.
  • Don’t run a generator inside your house, basement, garage or porch. It is safest to keep a generator outside, far from the house.
  • Never leave a car running inside a garage, even if the garage door is open, and never sleep in a parked car while the engine is running.

How Heat Pump Systems Work

In the warmer months, the heat pump acts like a regular air conditioner, removing heat from the air inside your home and transferring it outside.

But the big difference is during the colder months heat from outdoor air is extracted and transferred to the interior of your home. It utilizes the outdoor condensing unit to do this. That’s why you see the outdoor unit running in the winter.


Year-round, energy-efficient indoor comfort for moderate climates – A central heat pump helps maintain comfortable temperatures inside your home and reduces humidity levels year-round. Homes located in regions with severely cold temperatures may either require supplemental heating or be better served with an air conditioner/furnace combination.

Cleaner air – As your heat pump system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply duct-work that carries it back to rooms. Whenever the air conditioner is running, this cycle repeats continually, constantly filtering and cleaning the air in your home.

Quieter operation – Because the compressor-bearing unit of the typical central heat pump system is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.
