Hello, my name is Dennis and I live in Manchester, England. I am really sensitive to changes in temperature and also suffer from hay fever so I don't like to open my windows. This makes the summer months can be a little uncomfortable. A friend suggested that I invest in an HVAC system and I did so. The HVAC system really made a difference to my life and I was pleased. However, last year, the HVAC system began to malfunction. I didn't know what to do but my friend suggested a HVAC contractor who was able to repair the system while also giving me some great maintenance tips.
