"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

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
