R.F. Ohl come out to my Bethlehem home to service the heating and cooling system. They serviced my gas HVAC system and my gas fireplace all in one trip, getting me ready for the winter. For the longest time, I have had a problem with one bedroom not getting enough heat in the winter or enough AC in the summer. Previously, I’ve had other HVAC companies try to fix the problem and they never could. R.F. Ohl’s technician was able to trouble shoot the issue and fix it in the same day! I definitely recommend using R.F. Ohl for your home’s HVAC, heating and cooling systems.

I recently had a problem with my heat pump’s condensation pipe. Ohl’s air conditioning contractors/technicians came out right away and diagnosed the problem quickly. They were very thorough in their explanation and very friendly as well. They fixed the problem, checked out the rest of the system and left my house clean. I would highly recommend them for any HVAC, air conditioning, or other heating system repairs.
