DO NOT USE... the worker was extremely aggressive with me... I was frightened in my own home, he became aggressive when I asked if he cleaned the heating unit... he was very aggressive saying I didn’t trust him... when I all I asked was a question... tried to get extra cash off me to clean extractor fans... still no word from the company... they told me he must have been having a bad day..... a horrific experience.... terrible service... AVOID AT ALL COSTS
