"Installed new AC and heater unit in April 2023. Had used Garrett prior as I found them reasonably priced. After the install, numerous safety/code violations were found when the unit was inspected. Among them were not adding a safety drip pan under the furnace, not installing a coil condensate drain correctly, running a flexible gas line into the furnace cabinet (a code violation), not terminating the electric correctly (a code violation), leaving exposed wires on the AC unit outside. The new owner claims it's not his responsibility to fix these issues. I'd steer away and go with someone that wants to back up their work (sorry, it's your work if you buy the company). Update as of 01/15/2025 Response to review and company response Jan 2025. Company DID NOT come out or even reach out to me regarding this. Tape and duct work repairs? When did you come to my house? Shows how dishonest this company is. Stay clear. Only excuses from this company (for example. we bought our business in 2024, not our problem!)"

FAQs for heating and air conditioning service projects in Alton, 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.
