Once older air conditioning and heating systems can no longer be fixed with repairs and maintenance, or those repair costs start to become very frequent and expensive, it may be time to consider a system replacement. With this upgrade, homeowners can expect improved energy efficiency, improved air quality, fewer system breakdowns, and lower energy bills. Additionally, modern systems can help add value to your property once it comes time to sell. Use this gallery to see recent installations our team has completed, and how the discreet system designs may fit into the layout of your property.

Outside Air Conditioning System Replacements

We replace outdoor units that have worn out or aren't performing as well as they used to for our Long Island clients. Here are some samples of before and after pictures of compressors that we've worked on in the area. Not only does it improve the overall efficiency of a home's ability to cool, it also looks more attractive.

Inside Air Conditioning System Replacements

Air conditioning systems often have air handlers that are responsible for moving the air evenly through your home. Often, these are located in basements and attics. Here are some samples of before and after attic air handlers that we replaced for our customers.

Hydronic Boiler Replacements

Hydronic boilers use water to conduct heat, making this system a highly energy-efficient option. This system is long-lasting with proper repairs and maintenance, but when it is time for a replacement, we are here to help. Here are some recent basement system replacements.

Boiler Replacement

In this edition of "Before & After" we'll tell you about how T.F. O'Brien helped a customer get the heating equipment they needed for both safety and comfort. Our customer had a 20+-year-old boiler that was still functioning but was emitting slight traces of carbon monoxide into the home. We removed the unsafe boiler and installed a brand-new one. We raised the new unit on cement blocks. We installed a new stainless steel chimney liner to ensure the exhaust flows safely outside of the house, and installed new piping and new circulator pumps for each of the heating zones in the home. Finally, we tested the system and made sure there was no carbon monoxide emission in the home. The customer now has a safe, reliable heating system that will last many years.

Steam Boiler Replacements

Steam boilers transfer heat from a fuel source to water contained within the boiler to create heat. this option can be more environmentally friendly offering the use of options for using alternative fuels. Contact us to find out more.

Boiler and Water Heater Replacement

In this edition of "Before & After" we'll tell you about how T.F. O'Brien helped a customer move from an old boiler and water heater system into modern, efficient equipment.

An existing customer had a very old boiler that continued to need repairs year after year. When it came time for a new system, we installed a brand-new boiler and a new indirect water heater. We re-piped all of the heating zones to save space and allow for easier access. We installed all new exhaust piping for both the boiler and the existing furnace as well. This system has been working great and is a much more reliable solution for the homeowner.

Boiler Replacement

For this Before & After, an existing customer called us because their boiler was leaking water. We found the boiler leaking water from a crack in the heat exchanger. This boiler was more than 25 years old, and all of the piping around the boiler was old and deteriorating, causing more leaks. We replaced the boiler with a new one. This is a very large (300k btu) boiler for a large home and it weighed more than 600 lbs, which meant we had to safely lower the new boiler down into the basement. Additionally, we installed all new piping around the boiler.

New Ductless System Installation

Ductless systems are a popular option for homes lacking ductwork. Since energy is not lost through ducts, nearly all air is heated. As shown in these images, the design of these systems in sleek and can unobtrusively fit into the design of any home.

Air Handler Replacements

Air handlers work with outdoor units such as an air conditioner or heat pump to distribute heated or cooled air through a system of ducts. This system helps to ensure proper air distribution, temperature control, and indoor air quality.

Air Conditioning Replacement

For this Before & After, a customer called us for service because her existing system was turning on, but blowing warm air. We determined that the system had a refrigerant leak and it would have cost thousands of dollars to attempt a repair. Not to mention, the existing system was roughly 20 years old!

Our customer wished to proceed with a new, more reliable system, so we installed a brand-new system with a new copper line set to ensure there would be no leaks anywhere. The old line set was not covered and ran exposed along the side of the house. We covered not only our new line set but the existing line set for the home's secondary system to make for a more aesthetically pleasing look on the outside of the house. We also spun the new unit so the service side of the unit is closer to the house, allowing the unit to look much more attractive to passers-by and the homeowner.

Air Handler Update

For this Before & After, we performed an air handler update for one of our service customers. While performing routine maintenance, we discovered several concerns with their old system, which was approximately 25 years old. The primary issue was a serious refrigerant leak, which lead to two options - a very expensive repair on an outdated system, or replacing the system with a new one. We installed a new system for the customer. We were able to re-route the drain lines under the floorboards and move the unit over, which provided more attic space for the customer.

Furnace System Replacements

There are different types of furnaces including gas, oil and electric. Each type has unique benefits and capabilities. Here are some recent basement replacements.

Gas Furnace Replacement and AC Installation

In this edition of "Before & After" we'll tell you about how T.F. O'Brien helped a customer move from very old equipment into a modern and much more efficient system. A new customer called us looking to get an estimate on replacing his gas furnace, which was more than 30 years old. Additionally, he did not have air conditioning in his home, so he wanted to not only upgrade his heating system but add AC as well. To accommodate his needs, we installed a new gas furnace with a new air conditioning system. Additionally, we modified and insulated the supply air ductwork to better fit the new system, installed new return air ducting, and added filtration. To properly finish off the project, we installed a new stainless steel chimney liner to ensure the system would exhaust safely.

Gas Furnace and AC Replacement

In this edition of "Before & After," a customer called us for an estimate on replacing an AC and heat system that was roughly 30 years old and not working very well. We ended up installing a brand new gas furnace with a new AC system. We installed new condensate drain lines and a new emergency drain pan to prevent any emergency condensate issues. The old system did not have an emergency drain pan, so if there was ever a drainage issue, this could have caused a terrible water leak. Then we installed new return air ducting and we insulated a significant section of the existing ductwork in order to increase the performance of the new system. Lastly, we replaced a large section of the gas pipe feeding the furnace, helping to ensure that the gas line is safe and free from any hazards.
