Frequently Asked Questions (FAQs)

Why is heating and cooling system maintenance essential? 

Heating and cooling systems are integral in maintaining a comfortable temperature in your home. The constant starting, stopping, and continuous running can lead to unexpected breakdowns. 

Preventative maintenance ensures your system is functioning optimally and can save you from costly major repairs. Maintenance inspections also alert you to indicators of a deteriorating system like soot, rust, rot, and corrosion.

What size of air conditioner do I need? 

Air conditioners come in various sizes, based on their cooling capacity for your home, measured in British Thermal Units (BTUs). A professional HVAC technician can perform a load calculation for your home or business, with most homes requiring a unit with a capacity between 12,000 and 21,000 BTUs.

What ratings should I look for when choosing an air conditioner? 

When choosing a new HVAC system, focus on ratings like SEER, MERV, HSPF, and AFUE, which indicate energy efficiency and performance. 

SEER represents how much energy you need to produce cool air, and new units must have a minimum rating of 14. MERV measures your air purifier’s effectiveness, HSPF gauges heat pump performance, and AFUE measures fuel efficiency when creating heat.

How can I tell if there’s a warranty on my HVAC system? 

Most HVAC systems come with a warranty for a certain number of years. Check the bill of sale, contact the manufacturer online, or check the owners’ manual for warranty information.
