"I Had 5 different bids on my bathtub and shower projects, Jim Needham was the most professional company I dealt with. Pricing is a concern ,and he came up with an amount I could work with. I am looking forward to having them install my products and I like the fact they are an actual plumbing company!!"

"The repair was made.  Sean, the service tech was courteous and professional and obviously knew what he was doing. He replaced the circuit board which took less than 1/2 hour and for that I was charged $597.00. Thinking that the circuit board was pricey (Sean, the service tech indicated so), I thought the repair bill of $597 was reasonable.  Only after calling some stores (the next day) and finding out a circuit board cost $125 did I realize I got ripped off. Controlling Systems labor charge for 1/2 hour work amounted to $472. I called the owner/guy in charge to request a refund for part of the labor charge. (I really didn't expect to receive anything) Not only did this person(whose name I wished I remembered, I would state it here) not want to hear my complaint, he hung up on me because he knew he ripped me off. He was rude and didn't want to hear my complaint. He obviously didn't want to hear anything I had to say, only stating that I agreed to the repair charge beforehand. To that he's correct, I did agree to the charge but when I asked Sean what was the cost of the circuit board, he said  $250-300. Now I know parts are marked up when purchased through a company such as CS but I still believe this company took advantage of me. ( and probably hundreds of others out there). Controlling Systems did not provide parts cost, labor costs, etc in their estimate which they used to (I had used them 3 years ago, but I won't ever use them again) Future potential customers take heed: I WOULD ALWAYS REQUEST THE ESTIMATE REPAIR BILL BE BROKEN DOWN to parts cost, labor cost, etc. And if they tell you they can't provide that, that's a good sign you're being overcharged.
Normally I am careful about negotiating and reading the fine print, etc. but this day I was distracted and the temperature was in the teens. I wanted the furnace fixed and I didn't have time to get estimates. Also if I hadn't  used Controlling Systems I would have been charged the $100 diagnostic(service) charge. Lastly, Sean intially quoted me $700. When I told him I was going to get other estimates, he lowered the estimate to $597.

"Like any plumbing job today, the cost of installation is rough two or three times the cost of the item. This is a product of shortages of skilled help and there is little to be done. If you want it done particularly with any speed you will pay these prices. The cost of a water heater installed is three times what it was only ten years ago."

Install Boiler FAQs, answered by experts

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.
