As temps and dew points climb this summer, air conditioning is top of mind for many homeowners. That’s why we compiled a list of the top cooling FAQs our customers ask, along with answers from our experts here at West Allis Heating & Air Conditioning.

What’s the best air conditioning option?

This depends on your cooling needs. Proper sizing is critical to finding the right system for your home. In fact, the right-sized system can save you up to 50 percent on energy costs. Another efficient cooling option to consider is a ductless split system. It’s ideal for areas without ductwork, such as sunrooms, or any areas that never quite feel cool enough.

How often should my air conditioner be serviced?

The WAH pros highly recommend annual maintenance to keep your system running at its best. A routine inspection and cleaning:

  • Improves energy efficiency
  • Reduces the likelihood of repair
  • Extends system lifespan
  • Enhances air quality

Consider signing up for our Comfort Maintenance Agreement, which includes regular inspections, discounts on services and products, priority scheduling, and so much more.

Another tip, make sure you don’t skip out on service—annual professional maintenance is a requirement to maintain manufacturer warranties on newer systems.

Does my A/C need refrigerant?

If your system doesn’t seem to be cooling as effectively as it used to, it might need a simple refrigerant recharge. Our pros know exactly which type to use and can have this done in no time. Just give us a call or schedule an appointment to have your system looked at sooner rather than later to stay cool.

What’s the deal with energy ratings?

The two you’ll see most for air conditioners are EER and SEER. Energy Efficiency Ratio (EER) measures the cooling output of an air conditioner divided by its energy usage under specific test conditions. Seasonal Energy Efficiency Ratio (SEER) measures the efficiency of cooling equipment based on a seasonal average (versus specific test conditions). The higher the rating for both, the more efficient the system.

How can I lower my energy costs?

There are a few different ways you can save this summer:

  • Upgrade to a newer, high-efficiency cooling unit
  • Use a programmable thermostat to adjust temps based on your needs
  • Use a ceiling fan to keep air moving throughout your home
  • Consider a ductless system in warmer areas to avoid turning the air down
  • Open your windows at night when temperatures drop (just remember to close up in the morning before temps start to rise again)

Can I use air conditioning to control humidity?

If your home feels overly humid, we have a couple of options that can help, including a two-stage air conditioner or dehumidifier. A two-stage air conditioner runs more often than a single-stage A/C, which means it removes twice as much humidity. This is a common solution for local homeowners, but we also recommend whole-home dehumidifiers which reduce overly humid conditions. Talk to our pros and they’ll help you decide which is best for your needs.

How can I maximize the lifespan of my A/C system?

Regular, professional maintenance is the best way to prolong the life of your air conditioner. In addition, make sure your outdoor unit isn’t blocked by any foliage or debris that could inhibit airflow. Closing blinds and shades during the day to minimize the amount of heat your A/C must offset will also prevent it from working overtime. Programmable thermostats are another efficient way to reduce air conditioning usage.

I need to replace my A/C—any advice?

There are many factors to consider when finding the ideal air conditioner for your home and lifestyle. It’s best to consult a professional to guide you through the A/C replacement process, from purchasing a new system to installation and unit operation.
