"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."

FAQs for heating and air conditioning service projects in Oak Lawn, IL
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
