Frequently Asked Questions About Hafeman's Heating & Cooling, LLC
What size unit furnace or air conditioning unit do I need?
The appropriate size of your HVAC system is critical for optimal performance and energy efficiency. An undersized system may struggle to meet demand, while an oversized one can lead to inefficient cycling. While a general rule suggests one ton of cooling capacity per 500 square feet, many factors influence the ideal size for your home. Our team at Hafeman's Heating & Cooling expertly assesses these factors to recommend the most suitable system for your specific needs. Contact us for a professional evaluation to ensure your HVAC system operates at peak efficiency.

Do I need to worry about the outdoor HVAC unit components in the Wisconsin weather?
While our technicians at Hafeman's Heating & Cooling will thoroughly inspect the mechanical and electrical components during service visits, we recommend periodic checks of your outdoor unit.

For any concerns or if you suspect a significant issue, our 24-hour emergency service is available to promptly address your HVAC needs.
What are furnace air ducts and how do they affect airflow?

Proper maintenance, including professional cleaning and sealing, is crucial for optimal airflow and energy efficiency. Sealed ducts in unfinished areas can improve system efficiency by up to 20%.

How can using an electronic programmable thermostat help me save money?

When properly utilized, it can yield savings of up to $180 annually on energy expenses. These devices allow for automated temperature adjustments during periods when you're away, at work, or sleeping. For professional installation of a programmable thermostat in northeast Wisconsin, contact Hafeman's Heating & Cooling to enhance your home's energy efficiency.
How often should HVAC filters be replaced?
HVAC filters should be replaced every three months, or more frequently in homes with pets, smokers, or high allergen levels. Regular filter changes can extend your AC unit's lifespan by up to 40%. To ensure you're using the correct filter size, consult with Hafeman's Heating & Cooling before making a purchase. Timely filter replacements are crucial for maintaining air quality and system efficiency. For those preferring professional assistance, we offer service plans that include regular filter changes by our experienced technicians.
What is a ductless air conditioner and how does it work?
A ductless air conditioner is a wall-mounted unit that cools your home without the need for ductwork or an air handler. Known for their efficiency and quiet operation, these systems can be installed in various locations throughout your home. Some models also function as inverters, providing heating capabilities. Multiple units can be installed to create customized temperature zones in different areas of your house. For expert ductless AC installation in northeast Wisconsin, contact Hafeman's Heating & Cooling.
What makes your duct cleaning process different?
At Hafeman's Heating & Cooling, we employ a negative pressure system for duct cleaning. This method creates a vacuum within the entire ductwork system, effectively extracting all dust and debris. Our approach ensures a thorough and comprehensive cleaning of your air ducts.
