"We were very impressed with Mike and his team. They were prompt, communicative and professional. We had not had our ducts cleaned for a considerable time and it showed! Integrity took before and after pictures to show their work and they did a phenomenal job. They also gave us pointers for things to watch for. We will definitely be using them again in the future and make this a part of our regular annual routine."

"My God! Dan came out this morning, I explained what was done, he went to work on it right away! My furnace stopped working December 25th, 2024, no heat till today! Keep in mind, the last technician I hired in January 2025, charged me 240 dollars for 20 minutes analysis just to tell me I need new furnace and AC central, my AC works beautifully. Then I used 4 space heaters to keep my house warm! Man my electric bill was over 400 dollars the first month and climbing higher each coming months till Spring arrived! I hired B & D Plumbing and Heater Co. to come out and finish the job. It was a gentleman name Dan, he did an extremely awesome job, telling me the details, explaining everything I needed to knowledge. And now the furnace works about as good as it gets beautifully. The impressive part, he took his sweet time. And the most impressive part was when he presented my total bill! I was about to have a major heart attack when I saw the bill! It wasn’t through the roof bill! Cheap cheap"

The installation was clean, completed on time, and everything has been working flawlessly. I highly recommend Prolific Mechanical to anyone looking for honest, high-quality HVAC work."

"We met serviceman Alex L. from DJ's today. He worked as long as it was necessary to diagnose and fix issues with our furnace humidifier. It needed several adjustments. He worked very diligently and the price was reasonable (especially by today's standards for pricing). We would definitely hire DJs again for other HVAC and plumbing work. We also appreciated the company's thoroughness in providing reminder calls and other contact on the day of service to ensure we met Alex at our home at the right time. This shows an emphasis on customer service that we appreciate. Both Charlotte and Karen were very helpful to us on the phone today as well."

Heating and Air Conditioning questions, answered by experts

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.
