Excellent installation service!




Review of R.F. Ohl

The installation team was very informative and did beautiful work installing my fireplace. They we're friendly and personable. Everything was explained and demonstrated in detail. However we were very disappointed and unsatisfied with the delay in services waiting for parts to arrive. We had to make several phone calls and complain to speed up the process. Waited almost 6 months to have fireplace installed. This has no reflection on the men who did installation. We were completely satisfied with that aspect.

Review of R.F. Ohl

Outstanding, fast, complete service. 24 hour turnaround from call to install! The quote was fair, the installation was performed very professionally. The crew (Frank and Mike) organized and neatly installed the new electric and plumbing connections, bleed the lines throughout the house and then gave good tips on how to get the most of the new heater. They took care of clean up and took away the old unit and everything else that was no longer necessary. We highly recommend them and are very satisfied. .

Tips on How To Hire The Best Heating or Air Conditioning Expert

Here are some tips on how to hire the best heating and cooling contractor for your demands. Check to see if the service technicians are NATE accredited. Having repair technicians that are NATE certified should be a requirement that all individuals demand.

Another point to consider is continuing education. Make sure to ask your contractor if they are continuously improving the educational foundation of their service and repair technicians.

Always be sure to request references. As you can see on this webpage, we have tons of great reviews from clients in Allentown. Certainly, we would more than happy to provide you with a list a references as well.

Ask about the types of services and agreements that the HVAC company offers. For instance, is there a preventative maintenance agreement or an annual tuneup servicing. These sorts of services help to preserve the operational effectiveness of the heating and air conditioning system. They also help to pinpoint potential problems before they become a major issue. We provide both to give you the ultimate flexibility and possibilities.
