"Mr. Bost did an excellent job for me for a reasonable price. I know he obtained the best deal for me on the furnace and the air conditioning unit. He answered all my questions. He was on the job when he said he would be; he was professional and courteous. The installation went smoothly, and I have had no problem with the furnace or air conditioner since they were installed in 2008."

"Henry initially was going to do the work on Memorial Day saying he worked all the time. After discovering that his supplier would not be working on Memorial Day he rescheduled to the following Friday and voluntarily knocked $200 off the price. Friday arrived and Henry & crew did an excellent job removing the old unit and installing the new unit. A week or so after installation I noticed some weird noises when the AC ran. They tracked down the problems to parts of the old system that they had not touched. System is now performing well. Would highly recommend to anyone."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"After calling four plumbers to service what we thought was a major drain leak (overflowing tub, flowing down to our main level ceiling), Fred called back shortly after I initially reached out and left a message with one of his staff members.  He wanted to know, in detail, what was going on and would stop to interject and to ask me questions to ensure that he understood the plumbing challenge.  He asked if we would be home for awhile.  I said 'yes', and he said, "I'm really close to your address, we'll be over there shortly to check this out."  They were prompt, courteous, and he took the time to troubleshoot and to decipher that it wasn't a plumbing or drain problem; it was a washer/dryer problem.  He suggested next steps; part of the equation was having an appliance repair professional out to fix the problem.  He asked me to call him back and let him know what the challenge was. I asked what I could pay him and he said, "Nothing at all."  My husband and I were floored!  For someone who went out of their way to help us and to not write up a bill in return made our day.  He was solutions oriented, he was thorough, and he was so compassionate.  He just really cared about our challenge and wanted to ensure that it was taken care of.  We'd call him again in a heartbeat!

FAQs for window a/c unit service or relocation projects in Manchester, MD

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.
