When the colder weather arrives, there is an increased need for heating, and some components require protection from the elements. It is a truism that equipment that’s called upon to work harder and for longer periods is more prone to failure. Keeping a system running smoothly in times of high demand can be tricky without regular maintenance. For this reason, we recommend that HVAC systems are maintained twice per year. Regularly scheduled maintenance before the summer and winter months arrive is a great way to maintain service, improve energy efficiency and limit downtime.
The Importance of Preventative Maintenance
Many people ignore the maintenance requirements of their HVAC equipment. There are a number of reasons for this; the equipment is out of sight and out of mind, and people want to “save money” by ignoring its maintenance needs. But checking and maintaining HVAC equipment will help you to avoid expensive repairs and lower your energy bills too. Adopting a proactive approach to maintenance is the best way to keep the HVAC system working at optimal efficiency, and you will save money in the medium to long term.
6 Tips for Preventative HVAC Maintenance
Let’s take a look at six preventative maintenance tips that will help you to protect your HVAC system against the winter weather conditions:
1. Check and Replace the Air Filter
We mention this task right at the top of our list for some very good reasons. A large number of HVAC system problems can be avoided and even solved at the air filter. Why? Well, the air in your home circulates multiple times each day through the air filter. The HVAC system relies on a steady supply of air to run efficiently, and when the airflow is impeded, the cooling and heating equipment will work harder. There are two consequences when HVAC equipment is overworked, the system is prone to failure, and more energy is consumed. But, there is a third problem, the clogged air filter will lower the indoor air quality (IAQ), which will be noticeable for people with allergies and pre-existing respiratory ailments. It’s important to check the air filter every month; if it’s clogged, it should be replaced or cleaned, as shown in the owner’s manual. If you only remember one tip on this list, take this advice to heart and keep the air filter clean and clear.
2. Checking the Air Vents
The air vents are the second aspect of your HVAC system that you need to check. Some of the problems that we covered in the air filter section above are equally applicable to the air vents too. Again, the circulation and recirculation of air from the HVAC system will continue whenever the heating or cooling equipment is running. As it travels around the home, the HVAC system will pick up a large volume of airborne particulates. These pollutants may include dust, dirt, pollen, pet hair, and more which will lower the IAQ. Another problem with these contaminants is that they accumulate inside the air vents, and they can create blockages that diminish the airflow. This can contribute to overworking the equipment leading to an increased risk of failure. Reaching into the air vent with a vacuum cleaner fitted with a hose attachment can remove some of this debris. But, this is not a substitute for professional air vent and duct cleaning.
3. Reprogramming the Thermostat
Many people are surprised that their HVAC performance and energy efficiency have degraded when the colder weather arrives. This may seem strange, but the problem is often a simple error because the homeowner forgets to reprogram their thermostat for winter! When you’re reprogramming the thermostat, it’s a good idea to lower the temperature at night because you don’t need that extra heat when you’re in bed. This will keep your home comfortable without over stressing the equipment and driving up the energy bills. Making a switch to a smart or programmable thermostat is another smart move because you have even more control, timing, and monitoring options. This helps you to set a lower temperature when you’re not at home, and then it can be increased when you arrive.
4. Adding Extra Insulation
Adding insulation for winter, where it’s needed, is an excellent strategy. Insulation may have an initial cost, but thereafter it’s a purely passive technology that costs no energy to run. The area where we waste the most money is the attic because treated air can escape. If you have sufficient attic insulation, you can ensure that the warm air stays indoors and the cold air stays outdoors. As an added bonus, adding insulation reduces HVAC system strain because the equipment doesn’t need to work as hard. This will make it much easier to maintain the temperature and the energy bills will be reduced. If you can see the floor joists or it feels icy cold in the attic, it’s time to add more insulation.
5. Covering the Outside AC Unit
The outside AC unit is designed to withstand a wide variety of temperature variances and weather conditions. But, it’s a good idea to cover the unit during winter to protect the equipment from hibernating animals, debris accumulation, and ice formations. You can find outdoor AC unit covers at many home improvement stores.
6. Annual HVAC Inspections
Adopting a proactive approach to HVAC maintenance is a great way to reduce the running costs and lower your energy bills. Why? Well, a professional HVAC technician can clean the system, spot small issues before they develop into large problems, and offer advice on changes that can improve performance and save you money. It’s a good idea to schedule an inspection in the fall to prepare your HVAC system for winter. But if you’re worried about the performance of your heating and cooling equipment, you can schedule an inspection at any time. Just make sure you have somewhere warm to visit as the HVAC technician works.
