Heating, ventilation, and air conditioning (HVAC) systems work tirelessly to keep homes comfortable throughout the year. However, without proper maintenance, systems are at risk of breakdowns that can lead to inconvenient and costly furnace repair or air conditioning service calls. By addressing a few routine tasks yourself and scheduling seasonal maintenance, you can help your HVAC system operate efficiently for many years to come.
This article provides tips for maintaining your HVAC system to minimize repairs and maximize comfort. Following these best practices will help prevent issues down the line.
Clean or Replace Filters Monthly
A dirty air filter causes a furnace or air conditioner to work harder than necessary. Clogged filters also restrict airflow, reducing efficiency and potentially causing premature component failure. Changing filters monthly is the most important maintenance task. Disposable filters are affordable and available at any home improvement or hardware store.
Annual furnace repair and air conditioning service ensures everything is working optimally and catches small issues before they escalate. Reputable technicians will thoroughly inspect components, clean and lubricate moving parts, calibrate safety controls, inspect ductwork, and test operations under load. Many issues found during routine maintenance visits are minor and inexpensive to address.
Inspect Venting Yearly
Gas furnaces require venting to safely expel exhaust to the outdoors. Over time, blocked vent pipes or cracked flue connections can allow carbon monoxide to seep into living spaces, posing a serious health hazard. Check venting for obstructions, corrosion, or other damage each year before the heating season, and contact a professional for any needed furnace repair.
Dead batteries in programmable or Wi-Fi thermostats prevent the furnace or air conditioner from operating properly based on temperature. Mark calendar reminders in spring and fall to ensure thermostats have fresh batteries for optimal performance as seasons change. Replacement is an easy DIY task in most cases.
Clean or Replace Air Filters in Ducts Annually
Like regular filters, those inside ductwork also collect dust and debris that can compromise airflow. HVAC technicians can access and clean or swap internal filters during annual maintenance visits. Dirty return duct filters impact efficiency and lead to premature wear of system components over time if not addressed.
Snow, ice, and debris that collect on outdoor heat pumps or air conditioner units interfere with air intake and outtake. This stresses motors trying to operate under load. Keeping the area around units clean helps prevent hazardous buildup and the potential need for furnace repair from winter weather events.
Scheduling Regular Furnace Repair and Maintenance
Deciding how often to schedule air conditioning service and other seasonal maintenance depends on factors like equipment age, installation quality, environmental conditions, and personal preferences. On average:
- Gas Furnaces: Annual tune-ups and inspections
- Heat Pumps: Semi-annual maintenance in shoulder seasons
- Central Air Conditioners: Annual spring start-up and fall winterization
- Humidifiers/Dehumidifiers: Biannual cleaning and filter changes
- Thermostats: Replace batteries twice yearly
Reputable HVAC contractors provide reliable service at fair prices. Ask about maintenance plans bundling seasonal check-ups for convenience and potential savings. Equipment under warranty may require factory-authorized repairs as well. Addressing smaller issues promptly helps avoid larger, more complex repairs down the line requiring furnace repair or replacement altogether.
