Tiger Plumbing, Heating, Air Conditioning, & Electrical Services takes pride in being your preferred local plumbers, electricians, and HVAC technicians! In fact, more homeowners in the St. Louis Metro East & Central Illinois communities we serve, say they would call us again before any other plumbing, electrical, heating, or air conditioning service!

"Ill keep this as short as i can, which isn't short given the multitude of screw ups on Tigers part. Overall the turn time was good and setting the appointment was easy, however the experience left ALOT to be desired. The initial person who took my call did not properly record the issue as described resulting in the first tech being unprepared to resolve the issue and a subsequent visit from an advisor. The advisor drew up several service offerings and made a few recommendations for upgrades and enhancements to our existing system, including pointing out a possible safety issue. As part of that she made mention that they would have to remove a small portion of dry wall in the upstairs laundry closet to complete the flexible duct work which we agreed to. She scheduled the appointment for the work to be completed monday (it could have been done friday had the first call taker properly recorded the issue). The technician that showed up on monday was friendly enough however was unprepared to complete the work. Instead of a small hole in my laundry closet the duct work resulted in a hole in my kitchen ceiling spanning half the width of the kitchen, way more intrusive than what the advisor had set us up for. The technician also asked for my assistance multiple times, including to help pull duct work, which if im paying for a service, why do i have to help perform the service? The technician was also unprepared to clean up after himself as he needed to borrow my shop vac, paper towels, and cleaning spray. I guess his shop vac had been damaged on a previous job (again why am i paying you?). The technician also failed to perform all of the work that was paid for days in advance, more specifically they did not cap off the open flue from an old furnace which is a service that had been prepaid with the advisor. When asked about this the technician said he did not have the part, but if he came across one would "drop it off". After realizing this tiger was called requesting a refund for the unperformed work, at which point we were told "it could take up to a week for the supervisor to contact you to process that". Really? Your supervisors are too busy to ensure customer satisfaction in a timely manner, but you sure can come take someones money in less than 48 hours no problem.... I would not recommend them to anyone and definitely will not be using them again for anything. Attached is a picture of the small hole i was told would be left in my laundry closet. Please not that by laundry closet it ended up being kitchen ceiling, and by small hole, it was halfway across the kitchen."

FAQs for window a/c unit service or relocation projects in Belleville, 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.
