A well maintained or upgraded heating system performs more effectively and will be more reliable. Having a properly functional heating system is essential in the cold winter months. When it comes to heating your home or business, there are many different options. Boilers and Furnaces can be powered by fuel, natural gas, or electricity. It may also be possible to convert from one system to another.  However, having an underperforming system should not be an option.  If you undersize your new boiler or furnace you run the risk of overworking it and not getting the full life expectancy from it.  An underpowered system may not even heat the entire building.

So, whether you decide to install a new furnace, or a complete HVAC system for your home or an entire office building, our highly trained and experienced technicians will provide a high level of quality service you can depend on.

Air Conditioning

Ductless Air Conditioner, Central Air Conditioner, Mini Splits, Air Purifiers

There are various energy efficient options available for cooling your home or business. However, the SEER rating (Seasonal Energy Efficiency Ratio) is not the only thing you need to consider when deciding on what type of cooling system you want to install. With today’s technology it is possible to cool and entire home or building with different zones even without duct work adding more comfort and value to your home or business.

Each type of system is useful for certain situations. Having the proper heating and cooling systems installed will also serve to improve the air quality in your home or business. According to the Environmental Protection Agency (EPA), our exposure to air pollutants is significantly higher indoors compared to outside. Upgrading old equipment can improve the air quality which can have a direct affect on your well-being.

The latest research supports that installation of a germicidal UV air purifier inside your central air system is the best approach for reducing contaminants such as viruses (including COVID19), bacteria, mold, mildew and allergens. Giving you a safe and chemical free way to reduce airborne contaminants indoors.

Spray Foam Insulation

Attic, Basement, Crawlspace, Exterior Walls, Interior Walls

The U.S. Department of Energy estimates that 56% of the energy used in a home goes to heating and cooling. Making climate control one of the largest expenses of home ownership outside of the mortgage and can dramatically add to any businesses operating expenses.

Heating, Ventilation and Air Conditioning (HVAC) systems have a big effect on your utility bills and your energy consumption. Spray foam insulation can reduce the workload on your HVAC system, therefore making your home or business more energy efficient, which saves you money. The best option would be to have spray foam insulation installed during the construction or renovation stage so that you properly insulate the entire building envelope.  However, it has been proven that just having the attic, basement or crawlspace insulated with spray foam can greatly improve and eliminate air leakage in those areas, further reducing your energy consumption.
