If you’ve ever wondered what the auto setting on your thermostat does, how often you should change your HVAC filter, or why your furnace is blowing cold air, keep reading to learn the answers to these FAQs.
FAQ #1: What is the Auto Setting on the Thermostat?
Your thermostat has three modes: heat, cool, and auto. While heat and cool are pretty straightforward, have you ever wondered what the auto setting on your thermostat really does? Let’s break it down.
Heat mode keeps your home warm by using the furnace. Cool mode keeps your home cool by using the air conditioner. The auto setting uses both the heater and the air conditioner to maintain a consistent temperature.
Let’s say you want your home at 72 degrees year-round. If your home gets below 72 degrees, the heat kicks on. If it gets above 72 degrees, the AC takes over. No need to keep switching back and forth; it does the work for you.
The auto mode is especially convenient for times when the weather is unpredictable, like spring and fall. It may get down to the 40s at night, but when the sun comes up, temperatures can climb up to the 70s. When you set your thermostat to auto, you can get consistent comfort without the hassle, letting your HVAC system do the work.
FAQ #2: How Often Should I Change My HVAC Air Filter?
Changing your HVAC system’s air filter is a simple task, but it’s easy to procrastinate. Stop for a moment and think back to the last time you changed your air filter. If it’s been longer than 30 days, you’re probably overdue.
When your air filter is dirty, it reduces airflow, which means your HVAC system has to work harder to keep your home at a comfortable temperature. The harder your system works, the more energy it consumes, costing you more on your monthly utility bills. Plus, the increased strain puts wear and tear on your system’s components, shortening their lifespan.
Furthermore, dirty air filters are less effective at removing dust, dirt, debris, and allergens from the air. This negatively impacts your home’s air quality, potentially worsening respiratory problems like asthma and allergies.
The good news is that changing your air filter is quick and easy. The hardest part is remembering to do it, so set a reminder on your phone or make a note on your calendar. Swap out your filter every 30 days to save money and breathe easier. Your HVAC system will thank you!
FAQ #3: Why Is My Furnace Blowing Cold Air?
If you hold your hand up to the register and find that your furnace is blowing cold air, it can be alarming — after all, aren’t furnaces supposed to blow warm air? Don’t panic; there’s a common reason why this may be happening.
When your thermostat reaches the temperature you’ve set, the furnace shuts off the burners. However, the blower keeps running for a while to cool down the heat exchanger. This could be why your furnace is blowing cold air. So before you call a professional for repairs, check your thermostat. If your house is warm, your furnace is doing its job just fine.
