Best Boiler Services in Dallas TX

We contacted Big Bear upon recommendation from a friend and were not disappointed.  We subscribed to their annual service plan to maintain our two HVAC systems in the house we purchased within the last few years.

It was our first major checkup and they diagnosed two failing capacitors in our heating system and showed me (on the multimeter) why they were failing.  

They also re-taped the wiring/lines from our outdoor A/C condenser units that had been damaged by rats at no additional charge.

Great service, friendly staff!  Thanks, Claudio!

AC wasn't keeping up so my wife called Milestone and had them come out. My unit is under warranty and they said there was a leak in the evaporator coil. They had her sign up for a membership and told her it would cost almost 3k to replace under warranty? She paid half and they said they'd come back when the part came in. After she told me this I checked online and read
AC evaporator coil replacement costs $650 to $2,400 if not under warranty or $400 to $1,000 if under warranty for labor and refrigerant.
I don't understand why it cost so much. At this point they already have half the money and I'll end up paying twice as much as the high end recommended online.

Pros: Scheduling service was friendly.  Quote was free.  
Cons: Primary technician was rude and condescending (assistant was fine).  Quote was obscenely high.  My second quote from another company was less than half the amount Service Today quoted.  I ultimately hired a licensed individual who did the work for 15% of the Service Today price.  The work (replacing 8 working smoke detectors) took less than 40 minutes to complete.  Service Today quoted $800, $1600 if I purchased the detectors from them.
