"The technician arrived within a half hour of our initial call. Although he did not have the part on hand he made a quick trip to their service center and returned immediately with what he needed. The technician was prompt, professional, and knowledgeable. I feel it's also worth mentioning that the technician is also a combat veteran who served multiple tours overseas and is in the process of becoming a licensed plumber. I think it says a lot about a company who hires veterans. I'll never call anyone but Regional Plumbing and Heating for the types of services they provide."

"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."

"Called them as A/C was not working. They came out and refreshed freon. that was $215 fee. Our A/C was old and we were advised that it may or may not last. We decided to get a new A/C as ours was 20 years old. They advised me of the different models that they work with and gave me a written estimate and let me choose. The.y also subtracted the cost of the freon from the installation cost of a new A/C. One thing that was very impressive was that they were very punctual and gave us estimated time to have work completed. We ran into many other vendors who could not seem to provide accurate information. My wife and I felt an immediate concern for our worries from Oscar. We felt our needs were met and was very happy with service provided. I appreciated the way we were treated. This is a small business that seems to go the extra mile for you."

"My initial contact was with Chris Rounds who was very friendly and helpful in helping me choose my new roof. He is very responsive and easy to reach by phone. The crew came out on the day promised and started the roof removing process. The entire project took 2 days to complete. Each day, they picked up all shingles and roofing nails around the property and from what the crew told me, that was a LOT of nails. The roof is absolutely gorgeous!
A few days after install, we had a huge winds in our area and unfortunately a few shingles flew off. I called Chris and he had people out the next day to fix the problem. He explained that because of the cold weather and the newness of the roof, the shingles hadn't had time to seal together properly when the winds came in. I totally understand the unusual circumstance and in no way think they did sub-par work. The service was prompt and professional.
I would totally use All Star again if the need were to present itself. Great company. Great people.

FAQs for window a/c unit service or relocation projects in Cortland, IL

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
