Another important thing your house must have good heating system for keeping your house warm and comfortable. The most important thing in winter season is keeping your house and it is very easy to say but difficult to maintain. It is very difficult to maintain your heating system because of too much high electricity bills. If you are reluctant to do so because of the chilly weather and you don't want a 'cold welcome', set up a heating system with an inbuilt thermostat, which can stabilize the temperature automatically and even have timers in them. Close windows and ventilators during night and make optimum utilization of sunlight during day. These panels can store energy and are powerful enough to keep a house functional at night too. Besides erecting solar panels on houses, solar cells are now used for many appliances and devices. This inexpensive and trouble-free way of storing and using energy is now becoming the upcoming trend in the energy sector. Otherwise you can hire an 'external auditor' that has been trained for such purpose and are well-equipped for the assessment. They have the blower doors and infrared cameras to assess the loss of cooling and heat from a house. Any hidden holes and cracks are detected.

Removing leaks around your house will also help in controlling energy lost and hence higher bills. These leaks have plenty of contribution in high cost of power bills. These are the possible ways for air to go in and out of the house. This ultimately increases the workload heating/cooling system of house.
