"Project: Install a new HVAC for upstairs. Kevin came Friday afternoon to evaluate our needs and quoted me the pros/cons/prices for two different brands of HVAC. I selected the Goodman units and we agreed on installation to begin the following Tuesday at 9:00 a.m. with an estimate of 5 hours for completion. He arrived a few minutes early on Tuesday and completed the installation an hour ahead of schedule. He and his helper were very professional, courteous and helpful. The results have surpassed my expectation."

"This job is to fully replace furnace, air conditioning and ductwork plus adding additional cooling. Signed the contract on Tuesday morning and six hours later, my compressor gave up the ghost. Called J&J Burk representative, and they arranged a service call early the next day at my request. Confirmed the compressor had blown up and installed temporary AC units in two rooms to tide us over. In addition, the main project was scheduled for Monday, 30 March but the contractor offered to start the next day, Thursday 26 March. The work has moved along very smartly and I would give them a SIX on a scale of Five. The technicians are skillful, courteous and keep me informed at all times as to the progress. Looks like the estimated 5 work days will shrink to four, but not certain. Still, I am VERY impressed with this contractor and would recommend them any time. This is from a retired Civil Engineer who used to write contracts and specification for this sort of work at a nearby Air Force Base. This work is top-notch."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

FAQs for air conditioning projects in Lawton, OK

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.
