"Had 100 amp breaker replaced with 200 amp and multiple new lines run to the garage and added 100 amp in the garage. They were thorough and efficient and did the work as expected. Very professional and kept us updated if any potential delays and when new issues were found. I highly recommend and would hire again."

"I needed to find a company who could reroute my dryer vent in my home. Upon calling around it was hard to find someone who would do a smaller job. So I decided to make an Angi's post to see what I might could get. I was contacted by Matthew at Purity Air Restorations. He came to my home, inspected what needed done, was very knowledgeable on the best way to reroute the dryer vent and then gave me an estimate - very fairly priced. Then was able to put me on his schedule quickly. On the day of the job, his guys that installed the dryer vent, were professional, friendly, cleaned up their work mess and did a great job on their work. I am very pleased with my dryer vent. I would like to add that I did have one piece on my dryer vent that was a little tricky and Matthew went over and beyond what I anticipated trying to help me with it. I would definitely recommend them and use them again in the future! "

"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

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

AC capacitors last between five and 15 years, with an average lifespan of 10 years. Most people only need to replace a capacitor once during an AC unit’s lifetime. You don’t need to replace the capacitor unless something is wrong with it, which an HVAC repair pro can diagnose. 

You should schedule a full-service AC inspection at least once a year to ensure it works properly. During this time, your local AC repair pro will check:

  • Safety components, such as carbon monoxide leaks

  • Cooling components, like coolant levels 

  • Electrical components, such as inspecting fuses and wiring

  • Complete system services, like flushing the drain line

While you can DIY some aspects, like changing your air filter, it’s imperative that you call in a pro to inspect your AC for you. Your air conditioner has refrigerant that could be hazardous to your health if not handled properly, so it’s best to let a pro with experience take on this job.

You should service your AC at least once per year, in the spring, and twice per year if your unit is 10 years or older. As your unit ages, more maintenance can catch problems early and help the system reach its full lifespan potential, usually 15 years.

Get on your HVAC technician’s schedule in early spring so your unit is ready to go for the season. If you’re doing two inspections per year, aim for one in the spring and one in the fall. You should also service your furnace once per year in the fall.

Yes, ductless AC adds value to your home. Fixing or replacing traditional ductwork is an incredibly expensive and daunting prospect. Traditional ducts can be noisy and temperamental, with the potential for unwanted guests like hornets and rodents. Ductless mini-splits eliminate a major hassle and expense, so they can increase a home's value.
