"Had maintenance contract with Absolute to service HVAC, electrical, plumbing twice a year. On recent maintenance visit A/C condensation line was found to be clogged due to "dirt getting into the system from lack of filter maintenance". Cost $329 to clean line which was not covered under contract (and seems a bit excessive!!). Was told filter replacement was not covered in maintenance contract. Seems to me that this would be a priority maintenance item! Technician comment on last visit 5 months earlier stated filter was "still clean" and not replaced. Needless to say we will be finding another company to do our maintenance from now on."

"DO NOT USE THIS COMPANY. Please look at the YELP or BBB complaints, they are much more akin to what I experienced. They are certainly manipulating the Google reviews. I hired Lion to do a simple cleaning/certifying of our HVAC units as part of a sale. I was initially quoted $119, and I verified no less than 3 times with the customer service rep that the price would include cleaning and testing. When our tech showed up, he said we were misquoted and the charge for cleaning and testing would be about $450, as it was part of their "maintenance" package. They very reluctantly cut us a "deal" for just over $300. Not only was zero cleaning done, the tech did not perform a single action that could be classified as "maintenance." What we got was a diagnostic and estimate for repairs and replacement. I called to complain twice before someone finally got back to me. I was told that the tech didn't perform the cleaning because it may have damaged the unit, which was clearly a lie because the tech never told me that and actually gave me a quote to perform the AC coil cleaning, $470 (what a deal!). The rep then told me that a simple cleaning was done, but not the deep clean that I was expecting. I asked that my invoice be revised to reflect that, but was quickly blocked. Yes, they actually blocked my number after repeatedly misrepresenting both the price and work. I was shocked. I filed a complaint with the BBB, of which I discovered there are many. Hopefully they do the right thing and just give me a refund, but I won't hold my breath. Again, they are clearly manipulating their reviews on Google. Customers do your research!"

FAQs for window a/c unit service or relocation projects in Westminster, CO

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.
