If your home is cold even when it is hot outside this suggests that the insulation is good; if it were too hot in the summer and too cold in winter this suggests that heat is being lost too quickly in winter and gained in summer. The insulation stops the heat entering in the summer, keeping your house cool.
If the insulation is good then you might want to look at the heating system to see if it is performing well.
Beyond this guess, with the little information you have provided it is really hard to say anything more.
If might be helpful to look through this project which helps you to diagnose faults with central heating systems:
