EXCELLENT rating

Great results!! I must say the Gask Technical Services Team (Gerson) was quite efficient & detailed on assessing my residential HVAC needs... After trying out (2) other companies the past (2) years, it only took (GTS) maybe 5-6 hours to correct an HVAC issue i have been dealing with for years... Great install!!!! THANKS!

Gerson was so prompt and very professional. Our call was very last minute and he came right away to check out an issue we had with our heating system. He diagnosed the problem in all of 5 minutes and was back the very next morning to fix the issue we had. He even followed up to confirm all was still in working order. I would highly recommend him!
