"Greg came on schedule and discussed the project with us. He suggested LED pancake lights and dimmer. We originally planned to put in lights on either side of the room. He e-mailed a price by the end of the day. It was a fair price but over our current budget. We really only needed the lights on one side of the room (over the new office area), so I asked Greg to revise the estimate. It was not trouble and he did not try to push me into the original quote. We agreed on the price and he scheduled the work. Brennan came promptly and even texted me when he was close by so I could put the dog in another room. He completed the work very efficiently, cleaned up everything and was just awesome really. Everything is wonderful!!! I have found my electrician from now on!!!"

"It went great! Kevin and his crew went above and beyond my expectations. From the initial call, to the complete walkthrough free estimate, to the cleaning, Kevin kept us informed throughout the entire process. I asked for a thorough inspection and cleaning, and that is exactly what we got. They thoroughly cleaned and sanitized our complete HVAC system, including all supply lines, registers, and returns. They even removed and thoroughly cleaned the grills. They opened up the trunk lines and cleaned and sanitized them then sanitized with Foster’s 40:80 antimicrobial product. They sent me videos of their work as they were working throughout the house, and I was shocked to see mold growing in the attic unit. They cleaned and treated it, so hopefully our allergy problems will go away. Because they are mold specialists, I asked about a problem we were having with a leaking window. Kevin and his guys caulked the window and treated the interior wall and didn’t even charge me for the extra work. They were not the cheapest quote, but it was so much better than the last time we had vent cleaning, so the extra cost was so worth it! I highly recommend them and look forward to referring them to others and using them in the future."

"I have known Jacob for several years through his previous work with a HVAC subcontractor and was very excited to learn that he started his own company. I recently hired him to do a whole house HVAC install which included units, ductwork, and gas piping. As usual, his work was impeccable. He was clear and concise on his estimate and actually finished the job one day earlier than expected. I will definitely be using Three Rivers Mechanical on all of my future projects."

Heating and Air Conditioning FAQs, answered by experts

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

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.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.
