​​​T&T cannot stress enough the value of preventive H.V.A.C maintenance. On service calls we see again and again many air conditioner and heater problems that could have been avoided had the system been receiving regular care. Think of it this way: You would never drive your auto year after year without getting regular oil changes, tune ups and tire rotations. Heating and AC equipment is no different. Your heating and cooling systems work hard to keep you comfortable. They cannot perform optimally without regular attention. When you take good care of your heater or air conditioner, it will repay you with many benefits:

Small problems won’t turn into major expenses Heater and AC maintenance keeps your system in optimal condition Furnaces, heat pumps and air conditioners will last longer A well-maintained system is more energy-efficient, so it costs less to operate Prevents buildup of dust, dirt, and debris
Keeps potential problems from damaging other parts of the system
Heating and air conditioner service agreements are especially important after a new H.V.A.C installation. Investing in a heat pump, new furnace or energy-efficient air conditioner is a major expense. It can not only greatly improve your comfort, it can also increase property value and save significantly on power bills, so it only makes sense to take good care of the new system. Because we understand the value of H.V.A.C service agreements, we include a one-year preventive maintenance tune-up with all system installations 

Annual preventive maintenance is designed to keep your residential or commercial H.V.A.C equipment in prime condition. Older systems benefit from regular service because they will last longer and run more efficiently. Small problems can be fixed before they escalate, reducing the risk of equipment failure. T&T Cooling & Heating L.L.C offers value-added service plans for heat pumps, furnaces and air conditioners. 

Benefits include:

15% discount on parts and materials
Discounted per-hour cost
No overtime, emergency, or weekend charges

What is a Boiler?

A boiler is an enclosed vessel in which water is heated and circulated, either as hot water, steam, or super heated steam for the purpose of heating, powering, and/or producing electricity. The furnace of the boiler is where the fuel and air are introduced to combustion; fuel/ air mixtures are normally introduced into the furnace by using burners, where the flames are formed. The resulting hot gases travel through a series of heat exchangers, where heat is transferred to the water flowing though them. The combustion gases are finally released to the atmosphere via the stack of exhaust section of the boiler.


Total Efficiency Concept

Total Efficiency Concept is an innovative method to maximize the overall performance of a combustion process by measuring and controlling the different parameters corresponding to the four most important areas of process operation, which are Combustion Efficiency, Maintenance Efficiency, Safety, and Environmental Efficiency. By balancing all of the requirements set forth in each of these areas, it is possible to operate under conditions that allow for the most cost efficient and safe working environment, while still complying with the environmental regulations applicable to the combustion process.

 It is important to strive for perfect combustion efficiency, but many times perfect combustion efficiency is impractical due to the requirements of maintenance efficiency, safety, environmental efficiency, and fuel efficiency.Maintenance EfficiencyAlthough a brand new burner or boiler may run extremely efficiently with little or no problems, as time goes on, the same boiler slowly begins to lower its efficiency. This is because as a boiler or burner gets older it becomes dirtier and deteriorates. This affects the combustion process greatly and can seriously affect emissions and safety. In most cases, as a burner wears down, more excess air will be needed to ensure proper combustion and reduce CO emissions. To ensure that efficiency is maintained when a boiler ages, it is important to closely monitor the amount of O2 needed to produce proper combustion and CO emissions Safety, Safety is a major concern when dealing with any form of combustion. The toxic emissions that are released along with the risk of possible explosions can cause great harm. Older parts that are used in the combustion process can create more dangerous conditions. To ensure complete safety it is essential to monitor levels of CO and CxHy (hydrocarbons). It is also necessary to check the amounts of oxygen needed to ensure low levels of CO and hydrocarbons. CO is a toxic gas that can be lethal in higher concentrations. Hydrocarbons contain unburned fuel, which can cause explosions and consequently, great injury.Environmental Efficiency Toxic compounds such as sulfur dioxide, carbon monoxide, nitrogen oxides, and particles are undesirable emissions that are frequently results of the combustion of fossil fuels. These compounds cause smog, acid rain, and respiratory problems. In effort to reduce these pollutants federal and state laws have been established under the guidelines of the Clean Air Act and the EPA (Environmental Protection Agency). Combustion analysis aids in monitoring these toxic gases and meeting the regulations set forth by the government and EPA.
