Customer Testimonials

We had so much work done, new furnace, air conditioning, insulation, sealing the basement, and air duct cleaning, these guys are the real deal! Professional, knowledgeable, efficient, timely, we are so happy with the work they have done, our house is an old farm house from 1920, so you can imagine the obstacles that arise. I would highly recommend them!

Nathan and Keith are excellent technicians. Together they are a fast and efficient team. They were very respectful of us, our home, and pets. I will be referring Halco to friends and family. The difference is outstanding, I can't imagine what the impact on my electric bill is going to be! Thank you!

Excellent work, timely and very nice people. I would call them again for service without thinking twice about it.

Very prompt in responding to any request. Repair people are great--willing to explain problems and solutions and work until it is fixed no matter how longer or how late.
Can't recommend them enough for furnace and/or plumbing. The Gold Plan is worth every cent!

I had Halco insulate and air seal my attic and basement. Today, I received my first energy bill for a full cycle since the work was completed. My gas usage dropped 19% and my overall bill was 10% lower (gas and electric). I saw a reduction in my bill even though I kept the temperature warmer than before. I love the work Halco did in my home and can't wait to continue to see the results.

A great company. Been dealing with them for 10+ years for heating, A/C, insulation. Honest. Excellent technicians. Available in emergencies. Easy to talk with. Wish they were in my home state of PA.

Halco has been our maintenance and service provider for many years at our apartment building. They have been there when we needed them in the middle of the night to get heat back on for our tenants, they are always prompt with our annual service schedule and were very competitive when we needed a new boiler and fuel tank. Everyone we have dealt with has always been professional, knowledgeable and service oriented. I measure performance not only on quality of work and professionalism but on an organization's communication with the customer. Halco has always kept me updated on schedules and any issues related to their service.

I was very impressed with the service I received. The crew was on time for the appointment, they explained everything before it was done, they were very tidy, both inside and outside my home, my routine was not disrupted at all. All my questions were answered, they finished within the estimated time frame, they were professional and polite,. I felt comfortable having them in my home, and I felt respected. I highly recommend this company. I rate them at a 10+.
