Replacing your furnace is a major investment but it is also an opportunity to improve comfort, safety, and energy efficiency in your home. Choosing the right furnace and preparing properly can help you avoid common mistakes, reduce long-term costs, and ensure your new system performs reliably for years to come. Monterey Peninsula Sheet Metal & Heating would like to highlight some of the essential furnace replacement tips every homeowner should know before making the upgrade.
Do Not Wait for a Total Breakdown
The worst time to replace a furnace is when it fails during the coldest night of the year. Emergency replacements limit your options and often cost more. If your furnace is 15 to 20 years old, requires frequent repairs, or struggles to keep your home warm, start planning your replacement early. Proactive upgrades are less stressful and more cost-effective.
Choose the Right Furnace Size
Bigger is not better when it comes to furnaces. An improperly sized furnace can lead to poor comfort and higher energy bills. Having the right size is essential because an oversized furnace will short cycle and wear out faster. An undersized furnace runs constantly and struggles to heat the home. A professional HVAC contractor should perform a Manual J load calculation to determine the correct size for your home.
Consider Energy Efficiency Ratings
Furnace efficiency is measured by AFUE or (Annual Fuel Utilization Efficiency). A standard furnace is at most 80% AFUE, where high-efficiency furnaces has a 90% to 98% AFUE rating. Higher-efficiency furnaces cost more upfront but will greatly reduce monthly heating costs especially in colder climates.
Determine Fuel Type Options
Most homes use natural gas, but electric or propane furnaces may be options depending on your location and home setup. You will want to consider available fuel, utility costs and of course the existing infrastructure. Switching fuel types may require additional upgrades, so discuss this with your HVAC professional.
Understand Installation Costs & What’s Included
A furnace replacement quote should clearly outline:
• Equipment cost
• Labor
• Permits
• Removal and disposal of the old unit
• Any duct or electrical modifications
Beware of extremely low bids as they may not include the important work or use lower-quality equipment.
Choose a Reputable HVAC Contractor
The quality of installation matters just as much as the furnace itself. You will want to look for an HVAC contractor that is:
• Licensed and insured professionals
• Has a strong local reviews
• Manufacturer certifications
• Written warranties
A properly installed furnace runs more efficiently, lasts longer, and is less likely to break down.
