We are a Heating & Air conditioning company that specialize in heating & air conditioning installation and repairs.

"The technician was very professional and respectful of my home by removing and/or covering his shoes as needed. He kept me informed about his progress and issues he found as he continued his work. The furnace is very old, so he conducted research, determined the problem, got the needed parts and completed the job for a reasonable cost. I would definitely use his services again. 5 stars!"

Vent Heating & Cooling service is a family owned and operated company that has been servicing the La Grange Park, Illinois area for over 30 years. We offer comprehensive heating and cooling services to residential areas and are experts in our field. We have always been the preferred choice over our competitors. We can keep your family home at consistent comfortable temperatures at affordable prices. For quickest response please give us a call.

"This is our second year in our home and we realized last winter that our backroom addition had little-to-no heat flow and was frigid cold. Our goal was to make that room usable year-round. We bid with two other HVAC contractors and we pulled the trigger with Jim and his team. What put them apart was that they took their time assessing our home and situation, walked through all possible options, and clearly communicated those options. They evaluated and wanted to find the most feasible option for us, with efficiency and cost in mind. The other contractors came through and kind of already had their minds set on what heating system to use. Jim is also very personable, knowledgeable, and easy to communicate with. Jim and Carlton's proposal was the most cost effective overall - the unit/system itself and our personal ROI. It was gas as opposed to electric, the job was the least complex in terms of labor and construction, and it's functionality was worth the price."

Whether you need to have your air conditioning system completely replaced or you just need some basic heating repairs, call the friendly and professional technicians at Shavitz Heating & Air Conditioning. We value our Chicago heating and air conditioning customers and treat them like our family. We want you to be comfortable in your home. That is why we offer a 100% satisfaction guarantee and a lifetime workmanship warranty. Also, if we cannot install a new AC or heating system for you in a day, our technicians will deliver a portable heater or air conditioning system so that you can stay comfortable in your home. Call our team today to schedule HVAC services in the Chicagoland area.

"My simple advice is to ask for all costs upfront in writing. This was a two day job, but it should have been a one day job, I will get into that later. The repair was fine but the communication and billing was unacceptable. I was told by the technician in the field that the $179 Service charge would be credited to the final bill, which is what I am used to with other service comanies like plumbers. Because of that I agreed to the work. I was then surprised to see the service charge on my final bill as well as a $50 extra deposit fee. I called the office and they said that they never credit the service charge, perhaps it was a miscommunication error, and that they would correct the extra deposit fee. But there was no accountability or responsibility for their uniformed field tech who essentially lied to me. I feel it was dishonest and a bad business practice to not offer any kind of discount for their mistake. They also showed up the first day and then went to the warehouse to get the part but came back with the wrong part. They then had to reschedule for the following week because it was 3pm on Friday and the warehouse was now closed and they couldn't get the part until later. They offered to do the work over the weekend but that would incur overtime charges. I told them I would not pay overtime charges for a mistake they made getting the wrong part. Overall I am very dissatisfied with the company and would not recommend them."

Window a/c unit installations FAQs

Running a window air conditioner to cool a small room often costs less than $4 per day, making it cheaper than central air for single-room cooling. However, central air might be more efficient if you're using multiple window units or need to cool a space larger than 1,000 square feet. Choosing the right size AC is crucial—a unit that's too big or small can waste energy and increase costs.

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
