MCME MECHANICAL - Columbia's Certified HVAC Services

In our local climate, thermostat issues often start with simple fixes. First, check that it's set to 'Heat' or 'Cool' correctly and the batteries are fresh. Ensure it's level on the wall and not in direct sunlight or near a vent, which can cause false readings. If problems persist, it could be a wiring issue or a failing component. Our MCME technicians can perform a precise diagnosis and repair or recommend a modern, programmable thermostat to improve your comfort and energy bills.

This is a common question for many homes in our area. While repair is often a good short-term solution, systems over 15 years old are significantly less efficient and more prone to breakdowns, especially during our hot summers. We provide a thorough evaluation, comparing repair costs against the long-term savings and reliability of a new, high-efficiency system. We'll give you a clear, honest recommendation so you can make the best decision for your home's comfort and your budget.

Aging systems often give warnings before a complete failure. Key signs include reduced cooling power, longer run times to reach the set temperature, unusual noises like grinding or rattling, frequent cycling on and off, and a noticeable spike in your energy bills. To avoid a breakdown in peak summer heat, we recommend a pre-season tune-up. Our technicians will clean the system, check refrigerant levels, inspect electrical components, and assess its overall health to keep you cool all season.
