"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."

"So I've just sold my home in Lakewood and the Technicians at Time have come to repair a furnace motor and correct an code violation in my electrical panel that the city missed when I stalled 4 years ago. Their service has always been excellent. Madison returns messages first thing in the morning. The electrician Kevin Wendt explained the code violations clearly and corrected in 2 hours. I forgot the young man who repaired my furnace but he found the last motor in town for my model, potentially saving me having to spend thousands more. Home repair is never a pleasant experience but 3 times over the last decade, this business has given me peace of mind and fixed all issues quickly and professionally. Richard Gainer"
