FAQs: Air Conditioning

How do I know it’s time to replace my air conditioner?

If your AC is over 10–15 years old, breaks down often, or no longer cools efficiently, it’s time to consider an energy-efficient air conditioning replacement.

What size air conditioner do I need for my home?

Your AC size depends on square footage, insulation, and local climate. Our HVAC technician can perform a home cooling load calculation to find the right unit.

What are the benefits of upgrading to a high-efficiency air conditioner?

A high-efficiency HVAC system can lower energy bills, improve indoor comfort, and reduce your carbon footprint with ENERGY STAR®-rated equipment.

Should I replace both my furnace and AC at the same time?

Replacing both during an HVAC system upgrade ensures better performance, compatibility, and energy efficiency—especially if both units are aging.

What is SEER rating and why does it matter?

SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency. A higher SEER rating means lower operating costs and better AC performance.

How long does an air conditioner installation take?

Most air conditioning installations are completed in one day, though ductwork upgrades or system conversions may take longer.

Are there rebates or tax credits for new HVAC systems?

Yes, many homeowners qualify for HVAC rebates, energy efficiency tax credits, or utility incentives when installing a high-efficiency air conditioner. Contact our office for current savings opportunities!

Will a new AC improve my indoor air quality?

Yes—modern HVAC systems often include advanced filtration and humidity control, helping to reduce dust, allergens, and airborne pollutants.

How can I maintain my new air conditioning system?

Schedule annual HVAC maintenance, change filters regularly, and keep outdoor units clear for the best air conditioning performance and lifespan.
