"The unit is very old and it's not worth fixing as it needs to be replaced. The technician was very knowledgeable and informed me of my options. I have been using Shavitz for years and they replaced my main HVAC unit a few years back. They always come through and make it happen. When other companies say no, they try and come up with solutions to help."

"Vinny came over to my home the same day to give an estimate as I needed to replace my exisiting humidifier. I already knew it wasn’t working and super old so best to replace it. He explained everything to me when looking at my furnace room. Explained the different size and efficiency of the various models I could use with the size of my home. Quick to schedule installation as well :) I will definitely use this company for future HVAC needs!"

"Coldest Polar Vortex in history -44F, our 10+ year old furnace said no more. Travis, from Lifeline was here in 3 hours. We upgraded to a dual stage, 96%ECM, 100,000 BTU, HVAC. Travis also was able to get us a $450 ComEd rebate. Before leaving, he loaned us new, highly efficient space heaters, while they picked up our new system. Bob and John completed installation within 3 hours, no breaks. Its worth noting they also installed our A/C in 2017 with the same elitist standards as our new HVAC. I would highly recommend to family and friends. Lifeline has become like family, -perfectionist till the end. My hat is off to you, Lifeline."

Heating and Air Conditioning questions, answered by experts

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.
