Living in New England means living through all four seasons, and although we are known for our long, harsh winters, our summers often hit just as hard. Similar to most machinery and household appliances, your cooling equipment goes through normal wear and tear, so it’s essential you conduct a routine inspection of your HVAC unit. The benefits from a quick inspection are enormous; from limiting the intake of pollutants and unwanted contaminants to extending the lifespan of your equipment and improving energy efficiency. As we approach some of our hotter days, follow these tips to make sure your cooling equipment does not quit on you.  

Air Conditioner Filters 

Ensure the efficiency of your HVAC system by cleaning or replacing the filters. Clogged, dirty filters block normal airflow and reduce a system’s efficiency. Replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%. Clean or replace your air conditioning system’s filter or filters every month or two during the cooling season. 

Air Conditioner Coils  

A clean filter prevents the evaporator coil from soiling too quickly, but the evaporator coil and condenser coil can get dirty all on their own. They collect dirt over the months and years of service which can reduce airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and clean it as necessary. 

Seal Leaks and Cracks 

Harsh winds and flying debris can create cracks or loose seals in and around windows, doors, attics, and basements. Sealing leaks and crackswill maximize indoor air retention before the hottest months of the year arrive. At the same time, adding extra insulation in your home can be one of the most cost-effective investments you make because it increases the efficiency of your HVAC system and decreases your monthly utility costs.  

Benefits of AC Maintenance 

Now that you know what to do to maintain your HVAC system, it’s important to know why you should do it. Regular AC maintenance can improve your home’s air quality, offer greater energy efficiency, allows for fewer costly service and repairs, and can even prolong the life of your HVAC system. 

Hire a Professional  

If your HVAC system needs more than just regular maintenance, hire one of Daigle’s professional service technicians 

The technician should do the following: 

  • Check for correct amount of refrigerant 
  • Test for refrigerant leaks using a leak detector 
  • Check for and seal duct leakage in central systems 
  • Measure airflow through the evaporator coil 
  • Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously 
  • Inspect electric terminals and clean and tighten connections 
  • Oil motors and check belts for tightness and wear 
  • Check the accuracy of the thermostat. 

Regular maintenance to your HVAC system will ensure it’s ready for warmer days ahead. Schedule a routine inspection, thoroughly check the environment around your HVAC system, and test your A/C unit to get the most out of your HVAC system during the Summer.
