How often should I replace my furnace?

Generally, furnaces have a lifespan of around 15-20 years. However, factors such as maintenance, usage, and the quality of the furnace can influence this timeframe. If your furnace is nearing this age range or experiencing frequent issues, it might be time to consider a replacement.

What size furnace do I need for my home?

The size of the furnace required depends on factors like the size of your home, insulation, climate, and more. It’s best to consult with a Maichle’s technician who can perform a load calculation to determine the appropriate size for your specific needs.

How can I improve the efficiency of my furnace?

Regular maintenance such as changing filters, cleaning vents, and scheduling annual inspections can help improve the efficiency of your furnace. Additionally, upgrading to a newer, more energy-efficient model can lead to significant energy savings over time.

What are some common signs that my furnace needs repair?

Signs of a malfunctioning furnace include strange noises, uneven heating, frequent cycling, increased energy bills, and visible signs of damage or corrosion. If you notice any of these issues, it’s essential to have your furnace inspected by a Maichle’s technician.

How often should I schedule maintenance for my furnace?

It’s recommended to schedule annual maintenance for your furnace to ensure optimal performance and longevity. Regular maintenance can help identify and address potential issues before they escalate into costly repairs.

Can I install a furnace myself?

Furnace installation is a complex process that requires specialized knowledge and skills. It’s highly recommended to hire a Maichle’s technician for furnace installation to ensure safety, compliance with building codes, and proper functioning of the system.

What should I do if my furnace stops working?

If your furnace stops working, check for simple issues such as a tripped circuit breaker or a dirty air filter. If these troubleshooting steps don’t resolve the issue, contact a Maichle’s technician for diagnosis and repair.

How long does a furnace installation typically take?

The duration of a furnace installation can vary depending on factors such as the type of furnace, the complexity of the installation, and any additional ductwork or modifications required. On average, a typical installation may take one to two days to complete.

Is it worth investing in a programmable thermostat for my furnace?

Yes, investing in a programmable thermostat can help optimize your furnace’s efficiency by allowing you to set heating schedules based on your daily routine. This can lead to energy savings and increased comfort by ensuring that your home is heated when needed and saving energy when no one is home.
