"It went well. He was on time. He didn't find anything wrong with my system. He said the amount of freon in the system was just right--not too much and not too little. I liked that almost no freon appeared to leak out when he connected his equipment to test the level. He spent a lot of time with me and answered all my questions. He gave me an estimate for the cost of installing a new system. I think he hoped I would buy a new system, but I did not do so. I would buy a new system if I could convince myself that the  electricity savings would pay for the system within a reasonable number of years.

"This company was the second i had out to look at repairing our tankless hot water heater. For over a week the hot water would turn off randomly.  Baltica was my second opinion  for the repairs and i felt really lucky to have found them on Angie's list. The first company told me i needed to replace the entire 5 year old unit for $2200.00. Baltica answered all my questions before coming out,  Marius assessed the condition once  he came out,  the unit was flushed and clean out valves were installed he was very professional.  How nice to work with a company that stands behind their service.

Install Boiler questions, answered by experts

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.
