How Fresh Filters Benefit ACs

Monday, July 16th, 2018

man-with-fanIt’s past mid-July now, and that means that you have definitely been running your air conditioner for over a month. We really hope that you scheduled an AC tune-up prior to putting that air conditioner back into regular rotation—of course, it’s not too late to do so if you have not done so yet! One step that your technicians should have taken when tuning up your system is, of course, changing the air filter. Even if they did, it is probably time to do so again.

Washington DC Air Conditioning Tip: Air Filter Sizing

Monday, June 4th, 2012

If you moved into a new home or had someone change the filters on your Washington DC air conditioning or heating system for you, you may notice that whoever did the job put on the wrong size filter. This is not uncommon and is usually the result of an effort to save either time or money. However, in the long run it actually costs both. Here is how you can fix the problem of a wrong size filter.

The WRONG Way

If you have a filter that is too big for your system, it may seem like an easy enough fix– just fold it over or trim it down, right? Not so fast.

Folding the filter over makes for an imperfect seal. Air will leak through and around the bend, bypassing the filter entirely. This causes dirt and debris to build up on the fan, slows down air flow, degrades performance, decreases air quality and overall makes a big mess that you will have to pay to fix or clean up later.

Bending or cutting the filter also decreases its structural integrity. The whole filter can collapse while installed, creating not just a performance issue and a potentially costly repair, but also possibly creating unsafe conditions.

Furthermore, don’t give into the temptation to run your Washington DC air conditioning or heating system without a filter for the time being. The debris will quickly build up in your AC system, as well as being blown into your home. Heating and cooling systems should always be operated with the proper filter installed.

The RIGHT Way

So, what do you do when you have an air filter that is the wrong size? The only solution is to find the right size. If you are having trouble finding the right air filter for your system, try these tips:

  • Refer to your owner’s manual for the filter model number.
  • Bring the make and model information of your heating/cooling system to the store and ask someone there for help.
  • Have a professional inspect your system and replace the filter. (You should have a professional inspection once a year, anyway.)
  • For HVAC systems that are large or have special dimensions, special order custom filters to fit.

Above all, never operate your HVAC system without a clean, correctly sized filter properly installed. For more information about about which air filters are best for your system, give Polar Bear Air Conditioning a call!

Washington DC Heating Tip: Dangers of Not Changing Your Furnace Filter on Time

Wednesday, March 14th, 2012

Of the many ways to heat a home in Washington D.C., forced air systems are the simplest in function and the easiest to maintain.  They are so simple, in fact, it is easy to forget they need attention at all, but there are dangers to not changing your furnace filter on time that have a real and painful cost in efficiency and dollars.  Even health risks arise when filters have been neglected too long.

Contracting with a company like Polar Bear Air Conditioning ensures consistent maintenance and oversight to allow Washington D.C.  homeowners the comfort and relaxation you deserve in your own home.

Back to Basics

Usually in the basement or a central location, a furnace heats air to a temperature set by the thermostat.  Over the years, technological improvements have enabled furnaces to be much smaller and fit into closets instead of the large and gangly monsters of old that could fill an entire basement.

By a fan in the furnace, the warm air is circulated through filters into a system of ducts to be distributed to grates in the wall or registers on the floor.  A second grate and duct system returns cooler air back to the furnace to be reheated.

Water can be added at the furnace to humidify the air and filters are able to remove some of the dust that typically floats invisibly throughout a home.

The Dangers of Not Changing the Filter

When the system is properly maintained, it is clean, efficient and produces comforting heat on demand at the touch of the thermostat or consistently throughout the day and night.

The furnace filter is designed to remove dust from air as it passes through your furnace. The longer your furnace filter is in place the dirtier it becomes. The increase of particles caught in the filter creates resistance to air flow through the filter and reduces efficiency.

To make up for the loss of flow through a dirty filter, the heat exchanger, usually a gas or oil fired flame, must work harder to produce the same amount of heat to the space.  This becomes costly financially and causes undo wear and stress on the equipment, requiring a partial or full replacement much sooner.

Additionally, operating above ideal designed conditions, cracks in the chamber may appear from the over load which can allow carbon monoxide, a toxic gas, to be released into the duct work.  This gas in large quantities in the home can cause headaches, nausea, and in extreme circumstances, even death.

Regular Maintenance

To avoid problems and excessive strain, remember to change the filters at the beginning of each new heating season.  An annual maintenance, check-up and thorough cleaning by a qualified company like Polar Bear Air Conditioning ensures a safe and comfortable season of warmth with no need to worry about the dangers of not changing filters in your furnace.
