As the seasons begin to change, you will need to notice the cool winds begin to blow. That means that you have to prep your home’s air conditioning for this cooler season. Check out these tips from our HVAC experts:

Winterize the heating and cooling system. It's best to get a head start on winterizing your home before the temperature drops below zero. Follow Warner Service’s professional tricks:

  • Invest in draft snakes to prevent warm air from seeping out and vice versa.
  • Re-caulk gaps and repair weather-stripping on windows, piping, and foundation to save money on heating.
  • Change the air filter to alleviate autumn allergens and pathogens.
  • Call an expert to clean vents.
  • Run fans clockwise to reduce heating costs.
  • Lower temperature of water heater to around 170 degrees Fahrenheit.
  • Insulate pipes.

Schedule an HVAC maintenance check-up. To avoid emergencies and costly, unexpected repairs and replacements, this phone call should be made seasonally (every 3 to 4 months). For the fall, a professional should perform the following tasks on the central system:

  • Clean air ducts.
  • Check for correct amount of refrigerant.
  • Test for and seal leaks in ducts.
  • Measure evaporator coil’s airflow.
  • Verify correct electric control sequence.
  • Inspect electric terminals, and clean and tighten connections.
  • Oil motors, and check belts for tightness and wear.
  • Check thermostat’s accuracy.

Change your thermostat settings. When you change your clocks, change the temperature settings on your air conditioner's thermostat, too. With cooler temperatures, you should increase or decrease the temperature based on your comfort.

Run the heat. The first time you turn on the heat for the fall, it can smell. Usually, that burnt smell is dust that’s settled on the heating components over the last few months of being stagnant. It should go away quickly. If the heat doesn’t come on, call an HVAC professional.

Clean or replace your air conditioning unit’s air filter. Regularly clean and/or replace your air conditioning unit’s air filters about once a month (and always during the change of season). This routine cuts down on allergens and pathogens in your home and reduces your energy bill between 5 and 15 percent.

Remove natural debris from around the condenser unit. By the end of summer, dirt, grime, weeds, and leaves build up around the condenser unit. This can potentially disrupt clean airflow and hinder the efficiency of your HVAC system during cold weather.

Use a hose to remove all natural debris and clip overgrown grass. You should also rake any grass clippings, leaves, or weeds.

Clean your unit’s coils. The air conditioner’s evaporator coil and condenser coil collect dirt over the summer months from your lawnmower (and through the fall as the leaves change). This dirt reduces airflow and can cause your A/C unit to absorb heat. Clean the exterior area around the coils, and remove any debris.

Shut off the unit’s power. Shutting off the unit’s power averts any risk of condenser damage if someone accidentally switches the thermostat setting to "cool" during the fall. Look for a shut-off box on the exterior wall near your condenser unit and flip the switch inside.

Tip: Next spring, don't forget to turn the power back on 24 hours prior to using the A/C unit.

Add extra insulation. Use foam pipe covers around the air conditioning unit’s exposed pipes and wiring, particularly those that go into your home. You can also use duct tape to keep the foam insulation in place and to stop pipes from freezing and cracking.
