"From beginning to end, this was a very good experience.  The installation was a Carrier heating/air system.  The team arrived as scheduled, and it was an all-day job.  They were very pleasant while, at the same time, professional.  They had to install a new pad for the outside unit as the old pad was too close to the dryer vent.  Also, the inside installation was in a very small closet making it difficult.  Nevertheless, they were able to accomplish it in one day, and the clean-up and removal of the old unit was wonderful.  The unit is working perfectly, and I couldn't be more pleased.  I would highly recommend this company to anyone, and I will continue using them for regular maintenance.  "

"We needed some help with an electronic air cleaner we had installed by another hvac company (they claimed that the unit was working properly) Martin came by and confirmed that there was an issue. He spent time talking to the manufacturer and then helped us solve the issue in a timely and cost effective manner. He also did a routine yearly cleaning of our A/C unit and the furnace, and we are very pleased with the work and experience. 10/10 for communication, ease of scheduling, and value of the work. I highly recommend Martin for all of your HVAC needs"

"Since I have two furnaces, two air-conditioning units and a whole house air filtration system, it was too expense for me to afford the yearly service costs. Ed, the technician, and Steve, the Service Manager, helped me find filters that will help with my allergies and asthma and yet were affordable. I used the "Comfort Care" plan, which has discounts for parts and includes service for all my units."

FAQs for air conditioning projects in Louisville, TN

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
