"My husband signed a contract with Tony Shipman, boss of Precision Mechanical in Sullivan IN. (Terre Haute). We paid him $4,000 and the job is not finished. He promised to give us water lines, and upgraded electrical service, which has never been accomplished. There are also many damages that have been made. There is a hole in my kitchen wall, there are several deep ditches in our lawn, making it unsafe for our daughter to play and causing water build-up perfect for a mosquito breeding pool. They took the electrical prongs from our heater to place on the well pump! They even used my husband’s gas in the shed without permission. They used all the drinking water we had without replacing it several times. They also left trash behind on our lawn. Tony Shipman has said he would do the job multiple times but has not shown, or even notified us of the reasons for not coming as planned. Mr. Shipman is now ignoring calls and text messages as well. This has been ongoing for three months. Our family has been wronged; we are seeking justice. We cannot afford a lawyer and are praying we receive help. I do not want anyone else to be wronged by Tony Shipman and his crew with Precision Mechanical. Please, do not overlook this review. We thought he was a good option because our local news station (WTHI) has a positive report. I anyone and everyone to heed this warning so it doesn't happen again to an innocent family."

FAQs for heating and air conditioning service projects in Sullivan, IN
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.
