Bigger equipment is not automatically better comfort. šŸ 

Before choosing a replacement, start with your homeā€™s heating and cooling needsā€”not just the size of the old unit.

The U.S. Department of Energy explains that oversized equipment can cycle on and off too frequently, compromising comfort and efficiency. A residential load calculation helps inform equipment selection.

A useful question for your next estimate: ā€˜How did you determine the size my home needs?ā€™

Save this for when you compare replacement options.

A small check before heating season: how does your HVAC filter look?

ENERGY STAR recommends checking your filter every month, especially during heavy use. A dirty filter can restrict airflow and make your system work harder.

Check the filter size and type specified for your equipment, and follow the manufacturerā€™s replacement guidance. Different filter systems can have different service intervals.

Not sure which filter belongs in your system, or dealing with weak airflow? Message Lighthouse HVAC or call 443-343-7540.
