"Happy Holidays all! Please use my Holtzople (H) review to help you address your HVAC needs! Last summer, my Trane AC unit failed. Corey W (H) was the tech that came out to the house and troubleshooted/resolved the problem (leaking refrigerant). He also advised on probability of future repairs. Sadly, the unit performed well for only a short time before failing. It was time to consider my options. Repairs were becoming more frequent and costly. Tyler (H System Designer) visited and walked around my house inspecting my current HVAC system. We discussed repairing or replacing my ailing AC unit. He recommended replacing with a split ductless system and emailed a quote for 1. Enhanced Mitsubishi hyper heat mini split system (system) 2. Favorable financing options - low interest rates and affordable monthly payments. The install took a week. H’s crew arrived each morning, respected my property, and worked as a team to carefully install the new system. With gratitude, John"

"I had used No-Frost about ten years ago to completely replace the furnace and heat pump in my townhouse and also add an Aprilaire furnace humidifier. I chose them at that point not only because they were the low bid but because they explained everything clearly, provided great documentation and also were a Trane dealer and offered a ten year warranty. The installation and service in my townhouse were first rate and I had no trouble at all with the system for over ten years. We moved to another house less than a year ago and inherited a system with a very old furnace humidifier that the previous owner had not been using, had disconnected the supply and drain lines, and it had no filter. I called two contractors for estimates on replacing the unit. The first contractor sent a crew out to look at the system and give an estimate. When I called No-Frost, Eileen quoted me a price over the phone that was half the price of the other contractor. They would also give me a furnace/heat pump system check at no charge. Given my history with No-Frost, it was a No-Brainer. They were able to schedule within a week with an Aprilaire 600 with the advanced humidistat. The tech arrived on time. Our furnace and water heater are both tucked into a closet in our finished basement and there is not a lot of room to maneuver. Additionally, since we were replacing an existing installation, the new humidifier needed to fit in the same space. Initially, the tech had serious doubts about whether the new humidifier was going to fit. After some deliberation, we decided to give it a try. About twenty minutes later the tech called me down and showed me that it actually fit perfectly, with more than enough room open the unit to change the filter. Additionally, we had requested the Aprilaire unit with the automatic exterior humidity sensor. The tech explained to me that he had that system installed in his house and was not satisfied with the performance. There was a way to modify the installation to avoid running the outside sensor and improve performance, which he did. During the free system check, the tech also pointed out that there were signs of black mold inside the furnace. I had also previously noted some mold on one of the ceiling air vents. The tech gave me a recommendation for a duct cleaning company. Within two hours the installation was complete. There was an existing PVC drain line that went into the floor in the utility closet that we used for the humidifier drain. The system ran for about twenty minutes and all was well. About ten minutes after the tech had left, I started getting a puddle of water on the floor around the PVC drain. I shut the unit off and immediately called No-Frost. Eileen told me she would send the tech right back. Within ten minutes he was back, and he determined that there was a problem with the drain line that went into the concrete floor. I would need to call a plumber. Amazingly, I was able to get a plumber, Robert Bookhultz, out within two hours. They snaked the drain line to the outside, excavated the end (which had been buried under 6 inches of dirt), and added a 12 foot extension. Drain problem solved. The humidifier works great. Our HVAC system is about 15 years old and I will certainly call No-Frost when it is time to replace it."

"The process was easy and the service top notch from the estimate with the sales rep to scheduling and the install. Ill recommend them to anyone who needs heating and air services."

"Horizon Services was tasked to replace a 25 year old Central Air system. The team was on time, well mannered, polite, friendly, worked as one unit. Talking and giving suggestions to another if needed. Any mess they made, they cleaned up. I left the house to return to work. I left my cell phone number for them to call me if they completed the job prior to my return. they attempted to return items to their original space. I don't remember the crew taking a lunch break. I asked if anyone had lunch? They stated "finishing this job is more important.". The job took approximately ten hours. (Non stop) It was expensive, but worth it! When they removed the antiquated material it was replaced with brand new up to date equipment., The old equipment was taken away! I would highly recommend Horizon Services to anyone who asked."

"They (2 workers) did an EXECCENT job installing gas heater and Central Air unit. They were very polite and professional. I could not convince them to take a coffee break. Answered all my question. I'm soo happy I chose Blue Dot !! Also the price was unmatch... Thanks !! PS... The Wife is back to calling me HONEY again :)"

"The sales person, sold me a 15.5 seer heat pump and and the model it says 14.0 seer, so I asked the technician and he told me that, with both systems equal to 15.5 seer. I wanted to see 15.5 seer on the machine specifications but it does not said. So at this point, I donâ t know if the system installed at my house was 14.0 or 15.5 seer."

"EXCELLENCE! The team was amazing. We had a leak in the front yard and it took 'a minute' for the county to find our shut-off valve to determine it was our pipe. Gary from Heil came out on time to give an estimate and they were able to get Miss Utility out and do the work the same day, all in about 3 hours! They only had to dig one hole near the shut-off to replace the whole line. They also filled the hole back in AND SEEDED and put hay on top, and at my request wrapped caution tape around the area (so the area can dry out). The hole they had to drill in the wall in the basement was patched and their "Pullzit” method worked beautifully (I actually video taped it, it was awesome to see). Oh and they either took off their shoes or put on their own shoe covers when they came in the house (didn't have to ask). Thank you Gary, Ronnie, Shaun, Tatiana and everyone involved for resolving this so quickly and efficiently. We HIGHLY recommend Heil Plumbing!!"
