Ensuring your home has the correctly sized HVAC system is crucial for optimal comfort and efficiency. An undersized air conditioner, constantly running to keep up with demand, risks premature breakdown. Conversely, an oversized unit cycles on and off too frequently, leading to poor air circulation and uneven temperatures.

HVAC system size, typically measured in tons, indicates cooling capacity. While a general guideline suggests one ton for every 500 square feet, many factors influence the ideal size for your specific home. The Hafeman's Heating & Cooling team expertly calculates this to ensure your system operates efficiently and effectively. For expert guidance in selecting the perfect HVAC system size for your home, contact our team today!

At Hafeman's Heating & Cooling, we recommend that you have your system inspected by a professional HVAC contractor in the spring and fall to coincide with the cooling and heating seasons. This will ensure everything from the blower (the internal motor) to the thermostat is running smoothly. If you're looking to keep your home at an optimal temperature, contact the HVAC service northeast Wisconsin residents can depend upon.

While the HVAC professionals at Hafeman's Heating & Cooling will inspect the mechanics, electronics, and dangerous parts, you should walk by the outdoor unit every few weeks to remove any leaves, weeds, debris, and dead rodents. These can collect around the machine and cause damage, electrical issues, and, in some cases, fires. Contact our team today so we can quickly identify and address any issues your system may be experiencing. If you believe there's a major problem with your unit, we offer 24-hour emergency services in order to promptly address any issue.

Air ducts are the passages to connect and move the warm or cool air to the house. Ducts need to be professionally cleaned to actually remove all the dust and pollutants. Ducts are insulated and sealed. Leaky air ducts lead to poor airflow and quality.

Sealing ducts in unfinished spaces, such as attics, basements, and crawl spaces, can improve efficiency by 20% or more depending on the efficiency of the furnace. If you believe there's an issue with your ducts, contact the heating contractors northeast Wisconsin residents rely on. Hafeman's Heating & Cooling is here to help ensure your ducts won't cause any problems in your home!

Setting and programming a thermostat will stop your HVAC from running on overdrive. When used properly, it can help to save you as much as $180 per year in energy costs. Also, by using a programmable thermostat you can save yourself money when you're away on vacation, at work, or during the night. Contact Hafeman's Heating & Cooling when you're in need of an HVAC service across northeast Wisconsin and let us install a programmable thermostat in your home.

Your filter should be changed every three months each season or more frequently if you have pets, smoke, or have allergens in the house. AC units that receive regular maintenance can last up to 40% longer! Each house or unit has a different filter size, and some may even have more than one filter. Reach out to Hafeman's Heating & Cooling before purchasing your filter to guarantee that you have the correct-sized one for your unit.

Energy Star and other agencies that monitor energy efficiency report that changing the filter is a top DIY action item for a properly functioning HVAC system, as a dirty filter can increase energy costs and damage your equipment. Each time you replace the filter; you're helping to improve the air quality in the house. If you don't wish to replace the filter yourself, our team can place you on a service plan to have one of our many experienced heating and cooling technicians replace it for you!

A ductless air conditioner is one that hangs on the wall and requires no ductwork or air handler to cool your house. They're known for being efficient and quiet. Most people cannot hear the unit running. Because this type of unit requires no ductwork, Hafeman's Heating & Cooling can place it anywhere within your home.

It can also be sold as an inverter and heat your home. One unit can have multiple heads that can be placed in different areas and on different floors. All the different heads can be run at different temperatures to ensure each section of your home feels comfortable. When you're in need of AC installation across northeast Wisconsin, contact our team!

We use a negative pressure system, putting the entire ductwork system into a vacuum to successfully pull all the dust and debris out of it.

It's typically best to have your air ducts cleaned every four to six years, but each house is different.
