"I should have written this review a year ago when the work was done. I needed a new heater. A neighbor recommended Marshall Services. I have found them to be a knowledgeable, family-owned team that truly stands out. They’re remarkably adaptable to change—adjusting plans smoothly when new needs arise—and their communication is excellent: clear, proactive, and easy to understand. From the first conversation, their honesty and transparency inspired my confidence, and every interaction since then reinforced that trust. Most importantly, you can count on them. They follow through on commitments, keep you updated without asking, and deliver quality work with genuine care. The combination of expertise, reliable service, and that family-owned touch made the entire experience seamless and stress-free. Marshall Services is my go-to HVAC company and has my highest recommendation."

"Longacre is the best. I had an issue with my water heater. They contacted me so quickly, was able to get me scheduled same day and showed up within 1hr. By far the best. From the time they showed up they were very professional, clean and thorough. You gained a loyal customer. Thank you for your business."

"After signing up with Servicepro, I was on the phone with Horizon within 10 minutes. This was about 9:30 PM. They offered to come and fix the problem he next morning (day before Thanksgiving) but I declined because I was going away. Anyway I scheduled a 10 am appointment for Friday November 28, 2008 and they were very prompt. The techinitian expalined the issue and my heat was up and running within the hour. Very impressed with their service and professionalism. I am now signed up for annual check up for my HVAC system and would not hesitate to recommend them to others."
