Frequently Asked Questions about Furnace Repair

How can I tell if my furnace is the correct size for my home?

A properly sized furnace is essential for optimal home comfort. An undersized furnace won't adequately heat the space. An oversized furnace will short cycle, causing wear and tear, inconsistent heating, and inflated utility bills. Here are some signs your furnace may be improperly sized:

• High Energy Bills: An incorrectly sized furnace can cause increased energy consumption.
• Inconsistent Temperatures: Noticeable temperature fluctuations between rooms.
• Short Cycling: If your furnace turns on and off frequently, it may not be heating your space efficiently and wasting energy.
• Poor Air Quality: If the airflow from the vents seems weak or there are hot and cold spots, the unit may be the wrong size.
• Excessive Noise: A furnace that's too large may produce more noise than normal.

A qualified technician will be able to assess your home's heating needs. A Manual J load calculation can accurately determine the appropriate furnace size.. A proper sizing calculation is a worthwhile investment for optimal comfort and energy efficiency.

How often should I get my furnace inspected?

It's recommended to get your furnace inspected annually , to prepare for colder months. An annual furnace inspection by a qualified HVAC technician can help to identify potential problems early, extend the lifespan of your furnace, and ensure it's running safely and efficiently. .

What is the difference between a single-stage and two-stage furnace?

Single-stage and two-stage furnaces have operational differences.
Single-stage furnaces have only one setting, they either operate at 100% or are off. This can lead to temperature fluctuations and higher energy bills because the furnace is either running at its maximum setting or completely off..
Two-stage furnaces offer two levels of heat output: a lower setting for mild weather and a higher setting for colder temperatures. This allows the furnace to modulate its output based on the actual heating demand, resulting in more consistent temperatures, quieter operation, and improved energy efficiency. A two-stage furnace may be a more expensive initial investment, but it can provide greater comfort and savings over time.

What is a furnace tune-up?

A furnace tune-up is an annual checkup performed by a qualified HVAC technician to ensure optimal performance, energy efficiency, and safety. A typical tune-up involves several checks and maintenance tasks, which often include:

• Inspecting and cleaning the burners
• Checking the heat exchanger for cracks or leaks
• Inspecting the blower motor and fan
• Checking the flue pipe for proper venting
• Testing the safety controls
• Lubricating moving parts
• Checking refrigerant levels (for heat pumps)
• Testing for carbon monoxide leaks

Annual tune-ups maximize the life and efficiency of your furnace.
