F.A.Q.

Tom’s Heating Service has been serving Waukesha County homeowners for decades in solving heating and cooling problems of all kinds. To help you stay comfortable at all times, we put together a list of your most commonly asked cooling FAQs.

Does My Air Conditioner Need Maintenance Every Year?

Yes! Routine air conditioner maintenance is essential to keep it running safely and efficiently, while also saving you on energy costs. During our annual tuneup, our pros check refrigerant levels, clean out the outdoor unit, and address any existing problems before they worsen. You may extend your system’s lifespan, notice lower energy bills, and enjoy improved comfort and air quality.

How Long Will My Air Conditioner Last?

With proper annual maintenance, your cooling system can last anywhere from 10 to 15 years.

Why Is There Ice on My Air Conditioner?

Ice forms on ACs when there isn’t enough airflow over the evaporator coils. This often happens when the air filter gets too dirty. Your system could also be low on refrigerant. If you see ice on your air conditioning system, turn it off right away and let it thaw out. See if your air filter is dirty—if so, replace it. If the filter looks clean, contact one of our experts to diagnose and fix the problem.

What’s the Difference Between an AC and a Heat Pump?

The main difference is that an air conditioner provides only cooling comfort, while a heat pump can produce both hot and cold air. Air conditioners are more common in Southeastern Wisconsin, but heat pumps are more eco-friendly, as they transfer heat energy from the air outside instead of burning fuel to create it. Our experts can help you decide which system is best for your needs.

Why Is R-22 Refrigerant (Freon) Not Being Manufactured Anymore?

R-22 was found to have a serious negative impact on the environment and has been phased out of production. If your cooling system runs on Freon, don’t worry—you can still use it safely. Just know that any repairs you may need will be expensive because supplies are limited. Instead, consider a replacement system that is more cost-effective than an R-22 repair, and today’s units are much more energy-efficient than previous models.

Should the AC Fan Be Set to “Auto” or “On”?

It depends on how you prefer air circulation. The “auto” setting runs the fan only when needed to reach the set temperature—ideal for minimal cooling. The “on” setting provides consistent temperatures and uninterrupted airflow. It also helps alleviate allergy and asthma symptoms by constantly filtering indoor air. Our experts can help you choose the best programmable thermostat for your needs.
