- AFUE ratings measure how efficiently fuel turns into heat.
- ENERGY STAR models start at 90% AFUE for better energy savings.
- Electric furnaces offer 100% AFUE but cost more to operate long-term.
Selecting a furnace is not just about power, it’s about balance. Larger is not always better, and smaller doesn’t always save money. In Las Vegas, efficiency ratings also impact your monthly utility bills. Homeowners benefit from accurate load calculations to match furnace size to their home’s demands. This helps extend the system’s life while maintaining comfort. Always prioritize efficiency and system sizing when planning a new furnace installation. A well-matched unit will reduce repairs, lower energy use, and improve year-round comfort.
Comparing Gas, Electric, and Oil Furnace Options
Selecting the best energy source is essential to ensuring comfort and managing long-term heating costs in Las Vegas. Your options include electricity, gas, and occasionally oil.
Let’s look at the key energy source differences:
- Electric furnaces are easier and cheaper to install upfront.
- Gas furnaces cost more to install but offer lower monthly bills.
- Electric models often last longer, up to twice the lifespan of gas units.
- Oil furnaces are rarely used and more expensive to maintain.
- Each source has unique installation, safety, and cost implications.
- Choose an energy source based on utility rates and home infrastructure.
The decision you make today will influence comfort and cost for the next 15–20 years. While electric systems may look appealing due to low installation costs, their high operational expenses may cancel out initial savings. Gas furnaces offer stronger performance but demand regular servicing. If you’re still unsure, compare your expected usage with energy rates in Las Vegas. For long-term value and reliability, match the energy source with your home’s layout and your heating habits. Doing so ensures fewer breakdowns, lower energy bills, and better indoor air quality year-round.

Common Furnace Installation Mistakes and How to Avoid Them
A furnace installation requires more than buying a system and setting it in place. Overlooking key steps can lead to reduced performance, costly repairs, and long-term inefficiency. Many homeowners unknowingly make mistakes that delay installation or damage their new system. Understanding these errors can save time, money, and stress.
Taking time to avoid common mistakes ensures a successful furnace setup. In Las Vegas, factors like local codes, ductwork, and system compatibility make preparation crucial. Mistakes often come from skipping inspections or trying to save money upfront. Investing in a professional and well-planned installation protects your home’s comfort and heating reliability. Let’s explore these common missteps and how to prevent them.
Choosing the Wrong Furnace Size or Type
Selecting the wrong furnace size or system type is one of the most common installation mistakes. Many homeowners choose based on price, not fit.
Here’s what to watch for when selecting a system:
- A furnace that is too large short cycles and wears out quickly.
- An undersized furnace runs constantly and fails to heat properly.
- Improper sizing reduces comfort and increases energy usage.
- Climate, home layout, and insulation affect furnace size needs.
- Heat load calculations ensure a correct system match.
- Professional advice helps avoid costly sizing mistakes.
Improperly sized furnaces can’t maintain comfort and lead to unnecessary repairs. Bigger isn’t always better, and smaller doesn’t save money. Las Vegas homes have unique heating needs due to layout and climate. Choosing the right type, electric, gas, or oil, also matters. Switching types can require infrastructure changes and added costs.
Always consult a licensed HVAC contractor before purchasing. Load calculations based on your actual home will determine the ideal furnace. Smart sizing prevents headaches and maximizes efficiency from day one.
Skipping the Ductwork Inspection
Many homeowners overlook ductwork when replacing their furnace system. Damaged or outdated ducts can sabotage even the most efficient unit.
Consider these important ductwork facts:
