"Absolutely fantastic!!! Locating someone who is honest and competent is difficult to find in HVAC - if I took the word of every tech that said "you have a cracked heat exchange", who scared tenants into believing that they were dying from poisonous gases, I would be out $35k in under 2 yrs. (One of those claims was not a cracked exchange but a wasp's nest.) I found Mike's name on Angie's List after I took over managing our family's residential and commercial properties, and after being lied to or being mislead by incompetent techs. Other than familiarity with HVAC as a homeowner, my experience was limited. Mike helped me navigate through my "on the job" exposure, beginning with identifying for me the unique/odd/old units in some of our apartment buildings that some techs had never seen before. Mike was the 4th company in a row that I called who didn't work on that type of unit. But he was the first that didn't charge me a service call, and the only one who could identify the type of unit it was and who could work on them. Since that time, Mike has been my most prized contact! He arrives on time, is respectful to our tenants and their homes, and he has never walked away from a job because he could make more money on another service call - we had another valued HVAC contact who went MIA, stringing me along, while a post-op tenant was enduring week long heat wave. When I called Mike, he was out the next day, and had it fixed in three hours. It was a tedious job, but he did it. As long as I am responsible for our buildings, he will be first on our call list!! I believe in honor and loyalty, and this company deserves mine!!!!!"

"Emily was the product manager - she assessed the insulation we had, which was very inadequate, and gave us a range of upgrade options. A team of three guys did the work, solving some of our problems in a very resrouceful way. Then Emily came back and checked everything over. We were very happy with both the work performed and the customer service. The house feels unusually toasty now. We'll update this review in the spring after we see if we get our usual ice dams - hoping they're gone forever."

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

"Heath saved the day! I was hosting a afternoon party and woke up to a 62° house. After contacting Angie’s list for emergency service they recommended Heath. He was here within 45 minutes after contacting. He was pleasant, professional and knows his trade. After diagnosing the problem he said it was the intake motor, he examined it finding a blockage which he removed then cleaned. He even went the extra mile checking to see if the motor was still under warranty In case it was compromised and checked back with me the next day. He didn’t charge me an emergency call only the service fee which was very reasonable. I will use him in the future for any furnace or air conditioning needs as I know he is dependable, honest, skilled and a nice guy."

FAQs for air conditioning projects in Seward, IL

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.
