Maintaining Your HVAC and Plumbing in Gaithersburg, MD
Gaithersburg is no stranger to extreme temperatures, including a record high of 101 degrees Fahrenheit and a low of minus 7 degrees. In the middle of July or January, you count on your HVAC system to provide effective cooling and heating. Extreme temperatures require the equipment to work overtime, which increases the wear and chances of a breakdown. In winter, you run the risk of frozen or burst pipes.
The relative humidity can also create obstacles for the proper function of your HVAC in Gaithersburg, MD. With an average humidity of 70% in July, Gaithersburg residents use their HVAC and plumbing systems most often in the summer. Humidity can strain your HVAC system, and the heat and humidity could damage your plumbing.
