Maintenance and service play a key role in the life-cycle of a heating or air conditioning system. If all recommended maintenance and service actions are taken, an air conditioner can last 12 to 15 years and a gas furnace 20 to 25 years.

There are a few reasons why your furnace could be leaking water during the summer months. Some things you can try on your own are replacing your filter, hosing out the outside condenser, and pouring water or bleach through your vinyl condensate tube to alleviate any blockages.

If you ever see ice around your outside condenser or inside coil, the first thing you need to do is turn the air conditioner off from the thermostat and set your fan to “ON”. This will allow air movement through the system in order to allow that ice to thaw. Please keep in mind that if a technician arrives at your home and finds ice, there is nothing they can do to help you until the ice is thawed out. The second thing you need to do is call Lenz to schedule a service call.

If you feel lukewarm air coming out your vents rather than cold air, your unit could be low on freon or your system has some type of blockage that is not allowing cold air to flow. Again, you can change your filter and hose out your outside condenser before calling a professional at Lenz. You can also close your blinds and keep the windows and doors shut to contain prevent the cold air from leaving your home.

Typically, your air conditioner has the capacity to make your home 30 degrees cooler than the outside temperature. If the temperature in your home does not match your thermostat setting by +/- 5 degrees, it could be due to swift fluctuations in outside temperature. You’re A/C is working extra hard to keep up with the heat and humidity. Your unit often just needs more time to catch up.

If you can constantly hear your inside blower, first, check your thermostat and be sure that the fan setting is on “AUTO”. On 90+ degree days, your air conditioner may cycle on and off more often due to the fact that it is trying to satisfy your indoor temperature while the outdoor temperature continues to rise.

Humidifiers, specifically Aprilaire Humidifiers, have the ability to make the inside of your home 30% less humid than the outside. Use the table shown below to gauge what the humidity in your home should be at based off of the outside temperature.
