"This company came highly recommended, as many of today's technicians cannot service traditional "steam" boiler systems. Ever since last year's "furnace emergency", this "Old House" here found "its rescue match" with Pohlman Plumbing & CJ, a highly skilled specialist, who tweaked the boiler back to "steam". Explaining why my Amish-built "Oldie-Goldie" was here to last, CJ enjoyed "challenges" & was not trying to "up-sell". This positive experience of transparency & trust convinced us that we'd found "the" company for all our "Old House" future HVAC & plumbing needs, thx!"

"We came in to work one day, to find there was no AC in our offices. It was 90+ degrees that day, and as owner of the company, I saw that there was going to be little to no productivity that day. I called several companies, only to be told it would be a day or two before they could service our system. I was on the verge of sending everyone home, because the fans I purchased, just weren't doing the trick. Then, I called Paramount. Alan was at our offices within the hour. He determined it was a fan motor, and after a short trip to his office, had the new fan in hand. He also recommended replacement of a capacitor that he deemed to be on it's last leg. I figured he'd have to run to his shop again to get that, but he showed me a Full Stock of parts he had in his van. I'm in the Service Industry, and I have to admit I was impressed how stocked and organized his truck was. I was expecting a high bill, due to the response time and having to run back to his shop for fan. I was somewhat shocked how reasonable the bill was, and even added a little extra! Alan stayed around for a short time afterwards, and gave me some tips on what to do to keep my AC unit running efficiently. We have recommended Paramount to several companies and friends since this time, and they all have been pleased. We found our permanent Heating and Air company, and highly recommend Paramount to all. Thanks Again Paramount, and especially Alan, for doing a Great and Professional job! Russell with DTS Communications in Nottingham"

Heating and Air Conditioning questions, answered by experts

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
