"I waited a year and a half to file this review to be fair about my comments. I was at first put off by the fact that the son came over to give an estimate and he wrote about 15 words and a 16,000 dollar estimate with no description of the equipment or what all was included. He was strongly recommended by a friend so I went ahead and approved heat and air and new ductwork in my old 1954 3 bedroom house. He had an adequate crew to do the work and his father was very friendly. The work was adequate but after the job I found a lot to be desired. They left a lot of debris in the attic like old ductwork for me to remove. At every place they removed my freshly installed attic insulation to install new ducts and return duct they left all the insulation thrown about and nothing covering the areas around the ducts so I had to lowcrawl through the attic under all those ducts and reinstall all that insulation, which at my age (70 yrs old) that was no pleasure I can assure you.

"Josh was the tech that came out. He was very professional and clean. He was courteous and on time. He spoke clearly about what was going on with the A/C. He had everything he needed right then and there to find out what was wrong. Also, the problem should be fixed in about 2 days which is super fast compared to my experience with other repair companies. I would defiantly recommend."

"Mike is courteous and knows what he's doing. He's not as cheaply priced as some, but I have found that you get what you pay for. It's nice not to have someone come in for "re-do's.""

I have worked in many industries I worked in the automotive field for 10 years. I now work in supplying doors and trim for major builders across Oklahoma I am working directly with builders to find door hardware cabinet hardware as well as exterior doors. I have been doing lawn care for businesses and homeowners for the past five years, I’ve been helping family and friends and neighbors with projects that they’ve needed done, and I also manage my mother-in-law‘s rentals, I guess you could consider me a handyman or a jack of all trade. I’m just looking to help as many people as possible hopefully save them some money and gain some knowledge to hopefully expand into making this a full-time business. I will do my best to have fair pricing, I pride myself on being honest and straightforward with everyone.

FAQs for air conditioning projects in Duncan, 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.
