How To Change Your Furnace Filter

Posted on: January 31st, 2017 by Precision Temperature No Comments

Forced air furnaces require a filter to function properly and prevent pollutants from entering your home. This furnace filter needs to be checked every few months and changed when it is dirty; more frequently during the winter months when your furnace sees heavier usage. Here we provide a simple step-by-step guide to changing your furnace filter.

Step One

The first thing you should do before performing any sort of furnace maintenance is to turn off and unplug your furnace. Then you need to determine what type of filter you have. Your existing filter will be located inside the furnace or the air return vent and will have arrows on it showing airflow direction, which you will want to remember. It may help to write this down. The filter size will also be printed on the cardboard filter frame. If your filter has a plastic frame instead of cardboard, it’s reusable! You just need to clean it periodically with water and a vacuum, rather than replacing it.

Step Two

If you do need a replaceable filter, the next step is to get the right replacement. You’ll want to make sure to get the same size filter so it will fit your furnace correctly and allow it to function efficiently. Most hardware stores and home centers, as well as many online stores, sell replacement disposable filters. Your HVAC professional can recommend a correctly-sized filter that is effective at removing contaminants from your home’s air. For even more efficient removal of harmful air-borne particles, consider an air scrubber such as the Trane CleanEffects Air Cleaner, which removes up to 99.98% of pollutants and allergens from the air.

Step Three

Once you’ve located the correct replacement filter, all that’s left to do is install it. There will be markings on the filter that tell you which side should face the furnace. Slide your new furnace filter into place, keeping in mind the proper air flow direction, and replace any covers. You’re all set until it’s time to check it and change it again!

How to Weatherize Your Home and Save on Heating Costs This Winter

Posted on: December 15th, 2016 by Precision Temperature No Comments

Are you wasting money heating your home without properly weatherizing it? Weatherization helps you save money by helping you save energy on both heating and cooling, making it good for both your wallet and the environment! Home weatherization includes air sealing, improving ventilation, and adding insulation.

Precision Temperature Weatherize Home for Keeping Heat In

Air Sealing

Preventing outside air from leaking into and indoor air from leaking out of your home is an important, cost-effective way of lowering heating and cooling costs. After all, you don’t want the nice warm air you just spent precious dollars and cents to heat to the perfectly cozy temperature to leak out into the cold night air! And you especially don’t want that heated air to be replaced by cold outdoor air leaking into your home. Air sealing your home by caulking cracks and around door and window frames and weatherstripping doors can help reduce air leakage.

Ventilation

Of course, sealing all the air inside your home may not be the healthiest thing to do. Ventilation prevents pollutants and toxic contaminants from being sealed inside your home and helps maintain indoor air quality. Natural ventilation, spot ventilation, and whole-house ventilation are the main strategies you can use to achieve this.

Natural ventilation is usually the least useful strategy, due to its unpredictable and uncontrollable nature. A properly air sealed home will not be able to achieve sufficient air quality relying on natural ventilation alone because the usual cracks and holes it depends on will have been sealed to prevent the unpredictable and uncontrollable temperature changes that result from natural ventilation.

Spot ventilation helps make other forms of home ventilation more effective by removing air pollution and moisture at the source. Think of kitchen range hoods and bathroom exhaust fans. Spot ventilation is recommended for proper home ventilation and good air quality, but will not suffice as the only means of ventilating your home.

The most robust form of ventilation is whole-house ventilation. Whole-house ventilation systems use fans and duct systems to remove stale air from and bring fresh air into your home. This provides controlled ventilation throughout the house, with no unpredictable cold or hot air entering your home and raising your heating or cooling costs. Some whole-house ventilation systems can even help further reduce heating and cooling costs through changing the temperature of the air coming into the house by transferring heat to or from the air leaving the house.

Insulation

Properly insulating your home reduces heating and cooling costs and increases home comfort by reducing heat flow. Left unimpeded, heat flows from warmer areas to cooler areas. Insulation helps limit the transferring of heat into or out of your home, thus reducing the amount of energy required to maintain your desired interior temperature. A professional contractor can help you determine what type of insulation you need and where you need it, as well as help install it.

If your heating and cooling energy costs are still sky-rocketing after weatherizing your home, you may need a more efficient heating, ventilation, and air conditioning (HVAC) system.
