(StatePoint) Having a home cooling system that is working optimally is crucial to keeping your family comfortable.

To ensure your air conditioner (AC) continues to function properly, here are some tips for your heating, ventilation, air conditioning and refrigeration (HVACR) units:

  • Replace air filters. Ideally, homeowners should replace filters every three months (more often if you have pets) to ensure that air can flow efficiently. When air filters become clogged, your AC becomes less effective at lowering indoor temperatures. Additionally, prolonged use of a dirty or clogged air filter can prevent enough return air from entering and can damage the system. Keeping them clean can also lower your energy consumption by up to 15 percent, ultimately saving you money on energy bills.
  • Check your outdoor unit. Your outdoor unit’s ability to pull in air affects its efficiency. At least twice a month, check for weeds, debris, and potential obstructions. Keep vegetation at least two feet away from the unit.
  • Pay attention to your thermostat. Inspect your thermostat to ensure that it is running properly. If you are leaving the house, turn the thermostat down, but do not turn your system off. It is a common mistake for homeowners to think that turning it off will save them money, however, it costs more money because your system works much harder in order to completely re-heat or re- cool the entire house. Another common mistake is setting the thermostat to a very low temperature to cool the house faster, which does not change the rate at which your AC cools the space. Consider seeking an expert’s opinion on smart thermostats, which automate temperature adjustments.
  • Inspect condensation lines. Your AC unit removes moisture as it runs, and sends that water through a drainage pipe. A clogged line will prevent it from running smoothly and could result in costly water damage. Bleach can be used to help prevent algae and mildew buildup.
  • Schedule preventative maintenance. At least once a year, have an HVAC professional diagnose your unit to ensure it is running optimally. Technicians can check for damaged insulation around refrigerant lines or ducts with poor seals, all of which can cause your system to lose efficiency and increase your energy bill. A professional can also clean the AC unit by checking for and removing dirt or debris that may clog filters and coils.

Call a NATE-certified professional. Technicians certified by North American Technician Excellence (NATE) have proven their knowledge and expertise in HVACR by passing specialized certification exams. Electrical issues, compressor failure and frozen coils are a few common causes of unit failure, and finding a trained, qualified technician to resolve your issue is crucial. Visit the NATE website, www.natex.org to find more helpful HVACR resources and a local contractor that employs NATE-certified technicians.

By taking a few DIY maintenance measures, and by knowing when to get professional assistance, you can help keep your home cool and bills low.

(StatePoint) Do higher temperatures have to mean higher energy bills? The answer is no. There are numerous ways to keep your home cool and bills low in summer.

After a few months of disuse, it is vital to check that your air conditioning system is still working in an efficient and optimal manner. If you have a central air conditioning system, for peace of mind, you might want to have your system checked by an HVACR professional. In order to save, be sure to shop around for special deals, which are not difficult to find for seasonal preventive maintenance.

Understand however, that the proficiency of HVACR technicians varies greatly. When searching for the right HVACR technician for your home, one way to make certain that the job will be done properly and effectively is by hiring a professional certified by North American Technician Excellence (NATE), the nation’s largest certification body for HVACR technicians. NATE-certified technicians are qualified to properly install and service equipment, which means maximum home comfort and energy savings.

Once a technician has inspected your system for efficiency, there are a number of things you can do to keep energy bills low:

  • Clean your air filters. Check them every couple of weeks and change them at least twice in the season, or as directed by the manufacturer.
  • Don’t obstruct airflow around air conditioner units — keep them clear of plants and debris.
  • Raise the thermostat about 5 degrees. Each degree you raise the thermostat will save you a percentage off your cooling energy bill.
  • Compare energy bills from last year. If your costs have significantly increased, simply contact a qualified HVACR technician — he or she can help determine the source of the problem.

Remember, having an energy-approved, eco-friendly, high-efficiency product does not mean automatic money and energy savings. Proper installation, service and maintenance are important, too. So, do yourself a favor and request the service of an HVAC contractor who employs NATE-certified technicians. To locate one, visit the Homeowners section of the NATE website at www.natex.org, then enter your zip code on the locator map.

By taking proactive measures, you can rest assured that this season you will be cool while saving money and energy.

(StatePoint) Savvy homeowners know that with cool weather, comes a bit of preparation. A quick audit of your heating equipment can mean less wasted energy, a more comfortable home, and lower energy bills.

Nearly half of all heating and cooling equipment in U.S. homes never performs to its advertised capacity and efficiency due to incorrect installation, according to U.S. government estimates. And if you have an older system that was built before current efficiency standards, you could be spending more than needed on heating your home.

If it’s time to replace your system, be sure to have it properly installed by an HVACR professional, certified by North American Technician Excellence (NATE), the nation’s largest nonprofit certification body for HVACR technicians. NATE-certified technicians are skilled professionals who have proven their knowledge in the HVACR industry by passing specialized certification tests.

“The NATE-certified techs who perform the maintenance and repairs do a great job. We never have concern if the job is done right,” says Rob Kirkpatrick a longstanding customer of Thermal Services, a Nebraska-based contractor.

Beyond having an efficient heating system properly installed, you can prepare for the season in the following ways:

  • Clean heating filters. Check them every couple of weeks and change them at least twice in the season, or as directed by the manufacturer.
  • Check and maintain insulation. Improperly insulated walls, floors, attics, basements, and crawlspaces drain away heat and can also lead to moisture imbalance. Adding weather stripping and caulk around windows and doors can also improve a home’s insulation.
  • Turn down the thermostat or install a programmable thermostat to regulate temperature.
  • Clean the furnace area. Don’t keep chemicals or cleaning products near a heater, and don’t store anything next to it that could impede ventilation.
  • Free all vents and returns of obstructions. Don’t lay carpet over vents, place furniture over or in front of them, or obstruct the flow of air.
  • Dry air feels cooler than moist air, so install a humidifier. A simple humidifier may make the home feel five degrees warmer than a home with dry air.
  • Look into geothermal heating systems which use earth’s natural heat and are among the most efficient and energy-conserving heating and cooling technologies currently available.
  • For optimal performance of your HVAC system, get an annual maintenance plan which includes both heating and cooling maintenance. But take care to avoid poor service and scams. To find a qualified local contractor who employs certified HVACR professionals, look for the NATE logo or go to www.natex.org.

By incorporating a few energy-friendly habits into your routine and by making sure your heating system is operating optimally this season, you can keep utility bills low while maintaining a cozy, comfortable home.
