At C&J Well Co. Service, Pumps, & Drilling, we provide Central Indiana with state-of-the-art well and geothermal drilling and a full-service maintenance team. In addition to drilling, we perform service calls and maintenance checkups and replace pressure tanks and pumps in existing systems. C&J is a family-owned and operated business with a dedicated staff and many satisfied customers. We offer competitive prices without compromising the integrity of our services. Because our wells are drilled using the latest drilling technology, you are ensured to get the most out of your money. C&J Well Company is a member of the BBB, Indiana Ground Water Association, and the Builders Association of Greater Indianapolis. In a quarter of a century, there have been many notable accomplishments, such as opening C and J Water for softeners and treatment, and integrating other local well drilling companies. C&J proudly continues the legacies of Water Wells by Wilhite, Dean Well Drilling, Harness Well Company, and Scobee Well Drilling. Josh and Christy are grateful for their hard-working technicians and strong support staff that led the company through the years.

"Sat at 6AM my well sprung a leak and a gusher was shooting out of the ground. I call CJ at ^AM and the owner Josh answered (wow!). He said his excavation crew couldn't come come until Monday. I had weekend guests and wasn't too keen on going all weekend with no water in the house. Joosh asked me a couple questions. Do have a basement (yes I did) and is there a window in the basement (yes there is). From that he offered to send a crew to hook up a temp water supply to the house to get us trough the weekend. about 10AM on Sat two CJ repair guys showed up and hooked a bypass line from the well head through the basement window and tapped onto the main water supply line in the basement. What a life savor idea and our weekend went WELL ( no pun intended). Then on Monday morning the excavator crew shows up at 10AM and by 1PM the leak in the well pipe in the ground is fixed. I guess the u Bolt holding the pitless adapter to the casing rusted and broke, thus the water was pushing out as the pitless seal was now loose. The CJ crew explained all of this and kept me informed. My experience with Josh and his crews at CJ was top notch all the way! Thanks Josh for answering your phone on Saturday at 6AM repairs"

Boiler Repair questions, answered by experts

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.

There are likely dozens of HVAC repair companies that service your area, and choosing the right one can be a tricky process. To hire the right HVAC technician, we recommend reaching out to local companies and ask the following questions:

  • Are you licensed and insured?

  • Do you have any third-party certifications?

  • Do you often work on my specific type of HVAC system?

  • Do you provide any warranty for your work?

  • Do you offer maintenance contracts for ongoing savings?

  • How many years of experience do you have?

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.

There are a couple of signs that will tell you it’s time to bleed the radiator. If the radiator is making noises, it’s typically because of trapped air, which you can release by bleeding the radiator. You can also test the radiator by turning on your heat and then placing your hand near the top and bottom of the radiator. If you feel cold spots, particularly at the top of the radiator, it’s time to bleed it.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.
