Spring is here and that means spring cleaning for many people. You open the windows, air out the stale winter air, and do some vacuuming and dusting. But don’t forget about the maintenance of your HVAC system, either! When you’re spring cleaning the rest of your house, make sure you clean out your heating and cooling system, which has been working hard all winter long to keep you warm.
Your home’s HVAC system is essential to the comfort AND SAFETY of your family, and it can only do that if it is clean. Check out these tips to help you enjoy a safe and comfortable home this spring (and the rest of the year).
Maintenance of Your HVAC System
Before you do any cleaning, make sure the power to your HVAC system is turned off. That is most important for your safety. The last thing you want is to injure yourself. Even if you think you’ll be careful, it’s better to be safe; turn off your power as the first step any time you plan to work in or near your HVAC system. The reason is you don’t want your furnace or HVAC unit to come on while you are working on it.
There are a couple of ways you can turn off your furnace before you do any spring cleaning. Sometimes there is an on-off switch either on the furnace or close to it. Otherwise, you can go to your electrical panel and find the circuit that goes to the furnace and flip it to the off position. Also if you have a gas furnace or HVAC unit, such as a heat pump, you should turn the gas off to the unit. Find the gas line running into your HVAC unit and turn the gas valve coming into the furnace to the off position.
Clean Heating and Cooling Filters
Remove the filter in your HVAC system and replace it. Air is forced through the filter but that gets harder and harder for your HVAC system to do if the filter is clogged with dirt, dust, and debris. Replace your filter at least once every 3 months, depending on use and whether you have pets, allergies, and level of dust in your home. Only use filters that have been approved by the manufacturer so you don’t risk losing your warranty.
The filter to the furnace is typically where the cold air from the outside comes into the furnace. This can be on the furnace itself or in your house in the intake vent that leads to your furnace. For replaceable filters, there is usually a size of the filter marked somewhere on the filter. Find the filter at your local hardware store and replace it with the same size filter.
Some heating units have washable filters in which case take the filter to your sink or hose outside and run water over the filter until all dirt and debris have been washed off. A good tip is to write the date on the filter when you replace it, so you know when to replace it next. It is important to make sure the arrow on the filter is pointing in the direction of the airflow into your furnace. Central heat pumps and air conditioners will also use filters in the same way where they intake air into the unit.
Air Conditioning
If you have an external air conditioning unit, go outside and look at it. Make sure that the unit is free from debris that often accumulates around it during the fall and winter. Often, leaves and clippings will start to build inside the unit and at the vents.
While you’re looking at you’re air conditioning unit, clean the fan blades and the coils which can also pick up debris.
Clean Your Vents
Walk around the inside of your home and inspect your vents—the ones that blow warm/cool air FROM your HVAC system and the ones that pull air into your HVAC system. Make sure both types of vents are not blocked so that air can freely get in. This will not only ensure that you get clean fresh air throughout your house, it also helps you save money by keeping your HVAC system from doing too much work to draw in air.
Duct Cleaning
Think about the last time you had your ducts cleaned. If it isn’t in the last year then contact a company to come out and clean your ducts. All that dust and debris that accumulated over the winter can be removed so it’s not recirculating.
Proper duct cleaning is really a two part process to be effective. First remove debris and particulate matter that clings to your ducts and then suction to remove that debris. This is usually a job you cannot do without the proper equipment. Hunt’s Services HVAC technicians use Nikro negative air duct cleaning machines with compressed air whips that we run through each duct. The whips loosen all the dust and debris that collects in the duct system and then the negative air machine suck all the debris out of the system.
Reverse Your Ceiling Fans
Ceiling fans are a great way to reduce your energy bills by circulating the air in your home or business to either keep you warm or cool depending on the season. Make note of the direction of ceiling fan and make sure it is going in the correct direction. The general rule of thumb is the blades of the fan should turn clockwise in the winter, and the reverse in the summer. Run your ceiling fan at low speed in the winter to circulate your warm air and pull the warm air up and then push it downwards without creating a cooling effect from the fan.
Summary
Springtime is here and that means spring cleaning and enjoying the freshness of a new season. When you clean your home this spring, don’t forget about the HVAC system that has been working so hard all winter long, and reward it with a good cleaning… your HVAC system will run more efficiently and your family will be safer and more comfortable this spring!
