      Timely AC Replacement Can Reduce Maintenance Costs

      The decision to replace your air conditioner isn’t always easy. It’s a significant investment. This is why we always do our best to provide our customers with more cost-effective repairs when possible. However, if your older AC unit is on its last legs and showing signs of failure, replacing it will offer more long-term advantages. A new air conditioner can help you enjoy lower energy bills, provide superior airflow, and leave you with greater peace of mind.

      A wiring problem can cause your AC to stop working. Our experts will inspect your equipment and address any wiring or circuit breaker issues.

      These can become damaged or worn over time (similar to tires wearing out on a car). This is usually indicated by a squealing noise. Our technicians can check for this during routine AC maintenance.

      Do you hear hissing noises or notice foul smells coming from your AC? Chances are there’s a refrigerant leak. Avoid adding refrigerant on your own; an HVAC professional will know the appropriate amount to get your unit working at optimal levels again.

      This is often caused by poor circulation or lack of maintenance. You will know if your evaporator coil is frozen by the warm air leaving your unit.

      Your AC unit’s motor or compressor can wear out over time. After a careful inspection, we will carry out repairs or replace the defective parts.

      When it comes to air conditioning repair and maintenance in Columbia, MO, trust the expertise of Mastertech Heating & Cooling. Contact their team of HVAC professionals today at [phone number] to schedule an appointment and ensure your AC system operates at its best. Don’t compromise on your comfort and the performance of your cooling—rely on the trusted experts at Mastertech Heating & Cooling for all your air conditioning repair and maintenance needs.


      There could be several reasons why your AC is running but not cooling. It could be due to a dirty air filter restricting airflow, a refrigerant leak, a malfunctioning compressor, a faulty thermostat, or issues with the condenser unit. It’s best to contact a professional HVAC technician to diagnose and resolve the problem. They will have the expertise to identify the specific issue and provide the necessary repairs or adjustments to restore your AC’s cooling functionality.

      The cost to service an air conditioner can vary depending on several factors, such as the extent of the service needed, the size of the AC unit, and the location. On average, a basic AC service or maintenance visit can range from $75 to $200. 

      If repairs or additional work are required, the cost can increase. It’s recommended to contact local HVAC companies in your area for specific pricing details as they can provide accurate estimates based on your AC system’s needs and their service rates.

      The cost to fix an AC unit can seem high due to various factors. Firstly, the complexity of AC systems requires skilled technicians with specialized knowledge and training, which contributes to labor costs. Additionally, the cost of replacement parts and materials can vary depending on the specific make and model of the unit. Diagnostic tools, equipment, and overhead expenses also factor into the overall cost. 

      The need for timely repairs to prevent further damage or system failure may lead to higher costs. It’s important to remember that investing in professional AC repairs ensures long-term reliability and efficient cooling.

      The lifespan of an AC unit can vary depending on several factors. On average, a well-maintained air conditioning unit can last between 10 to 15 years. However, this can be influenced by factors such as usage patterns, climate conditions, installation quality, and maintenance practices. 

      Regular maintenance, including cleaning, filter replacements, and professional inspections, can help extend the lifespan of the AC unit. It’s important to consult with HVAC professionals to assess the condition of your specific unit and determine if it requires repairs or replacement as it approaches the end of its lifespan.

      Both of my recent needs were after hours. Out of the three plumbers that I called, Mastertech was the only one that responded and was able to help me... that day. That’s huge considering we are renovating the main level of our house, and five of us are living in our basement with one bathroom, and the water was off due to a leak. There prompt service was much appreciated.read more

      Our tech did amazing!!! He found all the leaks we had in our gas line and got it all fixed in a day. We were on a time crunch and had to get it fixed... before Monday so he came out on Sunday and stayed until he was 100%sure the line was working perfect. Had about 5 more leaks than expected and he was kind, patient, and hardworking!! He had a wonderful attitude even with unexpected problems and even when a wrench slipped and cut his cheek.
