"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

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

Yes, through thorough cleaning and inspection, optimizing functionality, and reducing energy use.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.
