Key Factors to Keep in Mind Before Installing a New Furnace
Choosing a new furnace is an important decision, and several factors should be evaluated before making a purchase.
- Size Matters: An undersized furnace struggles to maintain warmth, forcing it to work harder, while an oversized unit cycles inefficiently, increasing energy waste. Our experts assess your space for a perfect fit.
- Energy Efficiency: High-efficiency furnaces with advanced AFUE ratings optimize fuel use, lowering monthly heating bills while maintaining superior comfort. We help you choose the best energy-saving model for your home.
- Fuel Type: Gas furnaces offer affordability, electric models provide steady heating, and oil furnaces suit specific needs. We assess your home’s infrastructure and guide you to the most cost-effective option.
- Smart Thermostat Compatibility: A smart thermostat enhances your furnace’s efficiency by automatically adjusting temperatures, reducing energy consumption, and offering remote control for personalized comfort from anywhere.
- Proper Airflow & Ventilation: A well-ventilated system ensures even heating, prevents overheating, and improves indoor air quality. We evaluate your ductwork and airflow for maximum furnace efficiency and performance.
Choosing the right furnace involves efficiency, size, fuel type, smart technology, and proper airflow. Our experts ensure a seamless installation for lasting comfort. Contact us today for a consultation!
Pro Tips for Maintaining Your New Furnace for Years to Come
A properly maintained furnace lasts longer and runs more efficiently. Here’s how to keep your new system in top shape:
- Change Air Filters Regularly: Replacing furnace filters every 1-3 months helps maintain proper airflow, improves indoor air quality, and prevents dust buildup, ensuring your heating system runs smoothly and efficiently year-round.
- Schedule Annual Tune-Ups: Our licensed technicians perform a professional yearly inspection to identify minor issues before they become costly problems. This ensures your furnace operates at peak efficiency and extends its lifespan.
- Check the Thermostat: Verify your thermostat settings to match your comfort needs, and consider upgrading to a smart thermostat for better temperature control, improved efficiency, and lower monthly energy costs.
- Inspect the Vents & Ducts: Regularly check air vents and ducts for blockages or dust buildup. These can restrict airflow, causing your furnace to overwork and reducing your home's overall heating performance.
- Listen for Unusual Noises: If your furnace makes rattling, banging, or whistling sounds, it could indicate loose components or mechanical issues—schedule a professional inspection to prevent unexpected breakdowns.
