New Construction See our Builder & Remodeler page for details


An air conditioner is one of the most common appliances in homes today. Air conditioners require regular service to keep them up and running efficiently. Lack of continued maintenance makes an air conditioner diminish over time through each year of its operation. For instance, if you buy an air conditioner with an energy efficiency rating of 12, after a few years, if not maintained properly, your unit might start functioning like a unit with a rating of 9. Various researchers claim that regular air conditioning service and maintenance will enable a unit to function with up to 95 percent of its primary effectiveness. The results of such studies affirm that the amount spent on the annual maintenance of the air conditioner can be easily redeemed by saving the costs of repair as well as saving cost on your monthly electric charges.

toneproject.ru, like other air conditioning service companies presents special offers during the seasons of spring and fall. We also provide annual service programs to make your work easier. The air conditioning service checks must include the following: comparison of the unit’s operating temperatures and pressures with those specified by the manufacturer, oiling the fan motors, inspecting the compressor’s amp draw, cleaning the coils in the condenser, and inspecting the proper adjustment of the belts. toneproject.ru uses a 15-Point Check for all our customers.

One of the most vital parts that has to be inspected is the coolant level of the air conditioning unit. The coolant levels of air conditioners need to be monitored every year. All heating and air conditioning systems require periodic maintenance. This enables them to maintain their heating and cooling effectiveness, improve their service life and is important to reduce overall energy consumption.
