When to Consider Furnace Replacement

Your furnace works hard to keep your home comfortable, but like all appliances, it has a lifespan. Knowing when to replace your furnace can help you avoid unexpected breakdowns, high repair costs, and rising energy bills. At Aelott Air Conditioning, we help homeowners in San Marcos, CA make informed decisions with honest assessments and expert recommendations.

Here are key signs it’s time to consider a furnace replacement in San Marcos, CA:

  • Your furnace is over 15–20 years old: Most furnaces begin losing efficiency and reliability after 15 years. Older units can be costly to maintain and unsafe if not functioning properly.
  • Frequent repairs: If you’re calling for repairs more than once or twice a season, replacing your furnace will save you money and hassle in the long run.
  • Inconsistent heating: If certain rooms feel colder than others, your furnace may not be distributing heat evenly — a sign that it’s struggling.
  • Skyrocketing energy bills: A furnace that’s working too hard will drive up your energy costs. Modern, energy-efficient models can cut those bills significantly.
  • Strange noises or odors: Banging, rattling, or musty smells are signs that your furnace may be on its last leg.
  • Excess dust or poor air quality: An aging furnace can affect indoor air quality, leading to health concerns and discomfort.

If you’re noticing these warning signs, don’t wait until you’re left without heat. Contact Aelott Air Conditioning for a free installation estimate and learn how a new, energy-efficient furnace can make your home more comfortable and affordable to heat.

Choosing the Right Furnace for Your Home: What to Consider

Selecting the right furnace is a critical decision that impacts your home's comfort, energy efficiency, and long-term savings. At Aelott Air Conditioning, we guide you through every step, helping you choose a furnace that fits your home and budget while delivering reliable performance for years to come.

Here are key factors to consider when selecting a furnace:

  • Fuel Type: Choose between natural gas, electric, or propane furnaces. Gas furnaces are popular for their efficiency and cost-effectiveness, while electric furnaces are quieter and ideal for areas without gas lines.
  • Efficiency Rating (AFUE): The Annual Fuel Utilization Efficiency rating indicates how efficiently a furnace converts fuel into heat. Higher AFUE ratings (90% and above) mean lower energy waste and reduced utility bills.
  • Home Size and Heating Load: An oversized or undersized furnace can lead to comfort issues and wasted energy. We perform precise load calculations to recommend the perfect furnace size for your home.
  • Indoor Air Quality Features: Look for models with built-in air filtration, humidifiers, or variable-speed blowers that improve air quality and overall home comfort.
  • Noise Levels: Modern furnaces come with quieter operation features. If noise is a concern, we’ll help you select a system designed for silent performance.
  • Warranty and Reliability: We recommend trusted brands with strong warranties to protect your investment and ensure peace of mind.
