"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."

Heating and Air Conditioning questions, answered by experts

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.
