Why You Should Use Your Bathroom Exhaust Fans

Why You Should Use Your Bathroom Exhaust FansIf you consider why you should use your bathroom exhaust fans, odor control would probably come to mind first. Having fully-functional exhaust fans, that are sized correctly and installed properly, is important for a number of other reasons too, such as:

  • Preventing mold growth and structural deterioration. In our Georgia climate, removing excess humidity from the bathrooms helps keep mold growth in check and prevents damage to your drywall, paint, wood and structural components.
  • Preserving cooling efficiency. Getting rid of airborne moisture also helps the A/C operate efficiently so your cooling costs don’t increase.
  • Removing hazardous cleaning chemicals. With good bathroom ventilation, the leftover chemicals from commonly-used bathroom cleaners are less likely to degrade your indoor air quality.

Tips for Using Your Bathroom Fans Effectively

Here are some helpful tips on how to make sure your bathroom fans are working as effectively as possible.


  • Have the right capacity. You can have one or multiple fans in a single bathroom as long as they move sufficient cubic feet per minute (CFM) of air. Average-size bathrooms need one CFM of air movement for each square foot of space. Bathrooms over 100 square feet in size need 50 CFM more for each toilet, shower or bathtub, and 100 CFM more for a jetted tub.
  • Send exhaust directly outdoors. Bathroom fans should never be vented into unconditioned spaces like your attic because sending humidity up there can result in mold growth and structural deterioration.
  • Ensure efficient operation. Fans should be situated right over the bathroom tub or shower stall, and the entry door should have a half-inch clearance at the bottom so sufficient replacement air gets pulled in.
  • Make fan use easier. After each bathroom use, the fan needs to run for at least 20 minutes. This is easy to accomplish if you choose models with features like automatic start sensors, shut off timers or humidity sensors that automatically start and run the fan whenever there’s excess moisture in the air.

Basic Attic Fan Maintenance for Mid Summer Comfort

Basic Attic Fan Maintenance for Mid Summer ComfortWhen the hot summer sun has been beating down on your Peachtree, GA roof all day, it’s hard to keep your cool. It’s hard for your attic to keep its cool, too, without an attic fan. If your attic fan is broken or needs maintenance, even with your air conditioning running constantly, it can be difficult to keep your house cool.

Operating your attic fan when the air outside your home is cooler than the air inside will lower your indoor upstairs temperatures, resulting in reducing air conditioner expenses and overall home energy savings.

Basic Attic Fan Maintenance for Mid Summer Comfort

Generally, your attic fan won’t require annual maintenance, but should be inspected and professionally services every couple of years by a licensed HVAC expert. There are, however, a couple of easy maintenance task homeowners can do themselves:

  • Lubricate the oil ports every few years in order to keep the motor running smoothly and efficiently.
  • Clean the fan shutters that vent hot air from your home every few years.
  • Wash the fan blades every few years, to remove dust and grime.

Professional Attic Fan Maintenance

To keep your attic fan running in tip-top shape during the hot summer months, schedule a seasonal inspection and HVAC maintenance appointment. Your inspection may reveal that your attic fan needs maintenance, parts replaced, or a replacement of the entire unit. Common repairs include:

  • Direct drive: Units where the blades are directly connected to the motor generally are not reparable because there are no parts available. Models with timers and variable speed switches may be reparable if the issue is with the switch and not the motor.
  • Belt drive: While some whole house belt-driven attic fans can be fixed or adjusted, many times it is less expensive to just upgrade to a more quiet, energy-efficient model.
  • Attic exhaust fans: For these units, it is usually impractical to attempt repairs. Replacing the entire unit is the best option.

For more information about basic attic fan maintenance for mid summer comfort in your Fayette or Coweta County home, call the experts at Powers Heating & Air today.

Reasons Why Your Windows Have Condensation

Reasons Why Your Windows Have CondensationThe excess humidity that causes window condensation not only damages sills and trim, it can result in mold and mildew growth and degrade indoor air quality. If your windows have condensation, it’s important to identify the reasons why, such as:

  • Insufficient ventilation. Without adequate ventilation and air exchange, excess moisture from respiration, cooking, bathing and other daily activities can stay trapped inside a dwelling.

  • Inefficient windows. High humidity in a home is more likely to cause condensation on single pane windows that aren’t energy efficient.

  • An oversized A/C. An air conditioner that’s not sized correctly cycles on, quickly reaches the thermostat’s target temperature and then cycles off. With this repeated short-cycling, the equipment doesn’t stay running long enough to pull moisture out of the air, so humidity levels stay high.

The most effective way to reduce window condensation is to address the underlying causes:

  • Increase ventilation. The controlled air exchange provided by properly-installed ventilation fans or a whole-house system not only eliminates excess moisture, it helps remove volatile organic compounds (VOCs) and other pollutants and improves indoor air quality. Filtered ventilation also prevents pollen and other outdoor allergens from entering.

  • Operate the kitchen and bathroom exhaust fans. Cooking, running a dishwasher, showering and bathing can add a lot moisture to the air inside a home. Make sure the fans are vented outdoors, so that you’re not just re-circulating the moisture or moving it to the home’s unconditioned spaces.

  • Check the clothes dryer vent. If it isn’t vented directly outdoors, you’re adding humidity to the indoor air every time you dry a load of laundry. Make certain that the ducting is properly attached to the appliance, that it’s not blocked by a lint build-up, and that there are no holes that leak moist air.

  • Upgrade to energy efficient windows. Look for Energy Star-certified windows with a U-value of .30 and a Solar Heat Gain Coefficient (SHGC) of .30.

If your windows have condensation and you need expert advice on how to solve the problem, contact us at Powers Heating & Air. We’ve proudly served Peachtree City and the surrounding areas since 1979.

Don’t Overburden Your A/C – Lighten the Load on Your HVAC System

Don't Overburden Your A/C - Lighten the Load on Your HVAC SystemSummer temperatures are already here, and if you’re a homeowner or business owner in Georgia, your HVAC system probably gets a lot of use all season long. Unless you fully optimize its efficiency, you’re wasting money, and you might be overworking your air conditioner without even realizing it.

Whether you’re still in the construction process or have lived in your home for years, you have plenty of options for increasing your efficiency and lowering your bills. Don’t forget to schedule preventative maintenance for your HVAC system; you shouldn’t wait until a leak or problem for professional assistance, which includes everything from filter replacement to internal lubrication.

However, you can take matters into your own hands too. Make sure you have an energy-efficient summer by maintaining a regular duct cleaning regimen and inspecting your windows and door frames for any gaps or cracks. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends a few more helpful ways to lighten the load on your HVAC system this year:

  • Increase insulation levels (choose insulation with R-levels worthy of Georgia summers)
  • Choose high-efficiency roofing and window materials
  • Add shade (e.g. exterior awnings or thick interior screens) to windows
  • Add exhaust fans to rooms that tend to be more hot or humid, such as your kitchen, bathroom and attic
  • Use appliances (e.g. your washer and dryer) before and after the highest temperatures of the day; this peak period is usually between 10 AM and 4 PM
  • Turn off appliances when you’re not using them

It’s also important to make sure your HVAC unit is in a shaded area. Direct sunlight can make your air conditioner’s job more difficult, consuming more energy than necessary, so it’s a good idea to plant a tree nearby or install an awning above it.

For more information about HVAC efficiency and maintenance, please contact us at Powers Heating & Air in Peachtree City, Georgia. We have decades of experience keeping homes and businesses comfortable throughout Georgia, and we’ve been serving Fayette and Coweta counties since 2001.

Slash Your Home Heating Bill This Winter With These Surefire Tips

Slash Your Home Heating Bill This Winter With These Surefire TipsIs your home heating bill giving you the chills? Warm up with these surefire tips designed to slash heating costs this winter.

  • Install a programmable thermostat: It’s easy to forget to turn down the temperature when you leave home each day, but with a programmable thermostat, there’s no need to remember. Use this inexpensive investment to program setback periods while you’re away or sleeping without sacrificing comfort.
  • Replace old weatherstripping: Around 10 percent of your home’s heat loss occurs through windows and doors. This percentage increases if the weatherstripping isn’t doing its job. Cut down on drafts and lower your home heating bill by replacing the weatherstripping, an inexpensive, easy task you can complete yourself.
  • Change the filter regularly: A blocked furnace filter restricts airflow and makes the equipment work harder. Check the filter every one to three months and change it when it appears clogged with dirt. This simple step can help keep your home heating bill under control.
  • Install gaskets behind electrical outlets: A foam gasket helps prevent drafts that come in behind outlets. This tip is only effective on outlets located on exterior walls.
  • Add insulation to the attic: It’s a complete waste for heat to rise into the attic. Help keep warm air inside by laying down a thick layer of insulation all across the attic floor. Remember to keep the soffit vents uncovered. Also, don’t forget to insulate the attic hatch.
  • Use exhaust fans only as needed: While spot ventilation in the kitchen and bathroom is important for drawing pollutants outside, don’t use the fans when they’re not really needed. Running exhaust fans more than necessary not only increases electrical consumption, but it also depressurizes your home, encouraging outdoor air to seep in and undermining your furnace’s hard work.
  • Schedule annual preventative maintenance: Every fall, ask an HVAC professional to tune-up your furnace. Various aspects of the inspection, such as lubricating moving parts, reduce energy consumption and lower your heating bills.

For more tips to save energy and lower your home heating bill this winter, please contact Powers Heating and Air in Peachtree City today.
