"PIC really offers the sort of trades service we used ro find in Wisconsin communities. Scott explained different options with newer technologies before letting me decide what was right for us and our pocket book. We've had him do both AC repair work and installation and we're planning a garage heating system this fall as well. Fast, knowledgeable, and respectful of our circumstances. I highly recommend PIC for any HVAC need, large or small. I've talked to many others who have had the same experience with them as well!"

"Austin installed A/C in our newly remodeled home and we will continue to go through him for any future HVAC needs. He was efficient, thorough, and transparent throughout the entire process, answering any questions we had. As well as reassuring us we could reach out to him after the job was done if we ever had any problems down the road. We highly recommend his services and the peace of mind he provides!"

"We had a large drain pipe in the basement that would leak large amounts with big rains. We had another company (Best 1), come and tell us they needed to jackhammer out the cement, "order a part", and then they never called back. Dan's stepped in and visited within 2 days of our call, and had it fixed in two hours (no cement removal or special parts required). Best of all, it worked. I will be using Dan's from now on.

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Install Boiler questions, answered by experts

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.
