For optimal comfort and energy savings during summer in Southeast Pennsylvania, set your thermostat to 78°F (25°C) when you're home. If you're away, raising it to 85°F can help reduce cooling costs. Using a programmable or smart thermostat can make these adjustments automatic and more efficient.

How can I improve indoor air quality in Southeast Pennsylvania?

To improve indoor air quality in Southeast Pennsylvania, start by regularly changing your HVAC filters, scheduling routine maintenance, and using air purifiers. Consider duct cleaning if your home has excessive dust or allergy symptoms. Proper ventilation and keeping your home clean are key to healthier air.

How often should I service my HVAC system in Southeast Pennsylvania?

It’s ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.

How often should I have my air ducts cleaned in Southeast Pennsylvania?

It’s generally recommended to have your air ducts cleaned every 3 to 5 years in Southeast Pennsylvania, or more often if you notice dust buildup, allergies, or musty odors. Homes with pets, recent renovations, or high pollen levels in Lancaster may benefit from more frequent cleanings to maintain healthy indoor air quality.

How often should I schedule AC maintenance in Southeast Pennsylvania?

You should schedule AC maintenance once a year, ideally in the spring before the cooling season starts in PA. Regular tune-ups help your system run efficiently, prevent breakdowns, and extend the life of your unit, especially important in Southeast Pennsylvania's summer climate.

What size HVAC system is right for my home in Southeast Pennsylvania?

The right HVAC system size for your home in Southeast Pennsylvania depends on factors like square footage, insulation, number of windows, and local climate. A professional load calculation ensures your system is properly sized for comfort and efficiency. Oversized or undersized units can lead to higher energy bills and uneven temperatures.
