Keep your Arvada Home in the Best Shape with Seasonal HVAC Maintenance

Furnace maintenance is the process of professionally cleaning, inspecting, and tuning your heating system before the winter season begins. It helps identify wear and tear, improves efficiency and reduces the risk of breakdowns. Fall is the best time to schedule this service because it ensures your system is ready before the heavy heating season starts. Lakeside offers an easy, cost-effective HVAC maintenance plan to keep your system running smoothly and your home comfortable.

Adjusting Your Thermostat Settings for Fall and Winter

Fall is the ideal time to prepare your thermostat for dropping temperatures. Adjusting your thermostat now ensures energy savings and comfort all winter long. Even small changes to your home’s temperature can have a big impact on efficiency.

  • Lower the temperature at night: Reduce the temperature in your home by 7–10°F at night to save up to 10% on annual heating costs. An extra blanket at bedtime makes this an easy win.
  • Set a weekday schedule around your routine: Lower the heat when you’re at work and raise it before you return home.
  • Install a smart thermostat: Replacing your old model with a new thermostat with smart programming features to automate these adjustments and monitor your energy use in real time.

Have a Pro Check Your Ductwork & Furnace Flue

Ductwork and furnace flues are often overlooked—but vital—parts of your heating system. A professional can safely inspect these areas to catch issues early and improve performance before winter.

Here’s why it’s beneficial to entrust your air duct and flue examination to a professional Arvada heating services company:

  • Comprehensive Inspection: Experienced technicians can identify and seal air duct leaks in hard-to-reach areas like attics and crawlspaces.
  • Ensure Safety: A professional can identify blockages, corrosion or disconnected flue pipes that may lead to dangerous carbon monoxide buildup in your home.
  • Prevent Breakdowns: As they work, a heating specialist can look for other potential problems and inefficiencies that need to be fixed, saving you from an unexpected breakdown on a cold winter night.

Test Your Smoke Alarms and Carbon Monoxide (CO) Detectors

Fall is the perfect time to replace batteries in all smoke and CO detectors. You should also test them to make sure they are in good working order and check their expiration dates, since most devices only last 7–10 years. These small steps ensure you’re alerted in case of a furnace malfunction. If you need help or new CO detectors installed, Lakeside is the best HVAC company in Arvada to help you keep your heating system safe and efficient.

Clear the Clutter Around Your Furnace

Each fall, take time to clear at least 2–3 feet of space around your furnace. That includes clearing boxes, cleaning supplies or any other flammable items away from your furnace—and finding somewhere else to keep these items.

Keeping the space around your furnace clear of debris at all times prevents fire hazards and improves airflow, helping your system run safely and efficiently. Dust the area, vacuum any debris and check for items that could obstruct vents. If your heating system is outdated or unsafe, Lakeside offers expert furnace replacement and installation services so you can safely heat your home.
