"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

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.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.
