We came home late from work and found our AC had stopped working during the day -- it was the same temp inside as out. We quickly called Air Specialists around 7PM and shortly after 8PM Sam was there -- he quickly diagnosed our problem (having never seen our system before!) and also produced all the parts necessary to fix it. Before 9PM our house was cooling and Sam had finished -- he made sure the temperature was dropping and everything was working before he left. The cost was so reasonable -- we couldn't believe the great rate for after hours emergency service, the parts that were provided (we even needed a compressor!) and how quick the work was done. And Sam was so pleasant - and payment SO EASY! We're having them back the fall to check our Heating system and all our ducts -- This company will certainly have our repeat business for repair and standard servicing of our HVAC unit.
