"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."

"Alan is handy on everything we have asked him to do, as I am not handy. Personal, easy to get along with, answers all questions. From fixing ceiling fan, patch a roof, backboards for my horseshoe court. When ants destroyed would on window sills, Al took out bad wood and cut new boards and fitted. Also bathroom shower and fittings needed replaced, Al saw the problem and got the correct fittings and replaced. Al has been so helpful these 6 years we have known him. I can call text him and he gets back to me in a timely manner. I would refer Al to anyone doing anything they have. Al is the best"

"Sears' package of services allowed me to worry very little because they coordinated all the trades. Sears has a longstanding reputation for standing behind their products, something I had not found to be true with other contractors I had used in the past. Thecarpenter/job coordinator who did the refacing work was wonderful to work with, making minor modifiations as necessary to fit my needs.  I had not originally intended to purchase new appliances, but Sears offered me such a great discount that I added a new cooktop, double ovens (which required some cabinet modifications), and a dishwasher, which were installed by the carpenter.  He also coordinated the quartz countertop and flooring installations. All of the work Sears did was well done and professional. After the job was completed, I noticed that a door in the den that had to be cut off to accommodate the new flooring was a bit rough, and they sent the carpenter back to fix it within a week. I was somewhat concerned that I would not like the laminate used to reface the wood cabinets, but it has turned out to be very attractive, more durable than wood, and easy to clean.  No one can even find the seams in the quartz countertop or the Congoleum flooring, so I feel that their workmen are very experienced and skilled. I not only would recommend Sears to others, I would use them again for other work."

FAQs for window a/c unit service or relocation projects in Madison, WI

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.
