Fast, efficient, and professional. I went to turn my heat on and realized my boiler wasn’t working. It was a Friday before a long holiday weekend but James had one of his guys there first thing Monday morning and my heat was back up and running in just a few hours! Thank you so much!! Highly recommend
Met with me on short notice and took the time to talk about all options, but brief and to the point.
Helped me make a better decision.
Went above and beyond so the work got done in a timely manor and we're very satisfied with the results.
Thank you, James & Crew.
Excellent service. Responded quickly to confirm my appointment and the work was completed quickly the same day. We will be using this company for our yearly heating maintenance.
I had a great experience working with James and his team to install our new boiler and water heater. He worked to understand our needs, gave us solid advice, and provided a competitive bid with no extras or upsells (and no BS!). His work was very professionally done, and it was obvious that he took great pride in his work and in providing the most useful components. He also took the time to explain the work, how the equipment worked, and made sure the settings were what we we were looking for. All in all a great experience, and we will be working with him again.
An HVAC tune-up allows our expert technicians to inspect your system and confirm everything is functioning correctly. If components need replacement, we'll handle it before your system breaks down, saving you time and money while keeping your home comfortable all year long.
HVAC systems in our region typically run around 3,000 hours annually, which is why we recommend scheduling tune-ups twice a year. Regular maintenance helps catch small issues before they become expensive problems and keeps your system running efficiently.
HVAC maintenance involves regularly inspecting your system for issues, replacing worn components, and cleaning it to maintain peak performance. By investing in routine bi-annual maintenance, you keep your HVAC system running smoothly and prevent small problems from turning into major repairs, ultimately saving you money over time.
Most systems need professional service every 6 months to stay in optimal condition. Scheduling regular tune-ups ensures your HVAC system operates efficiently and helps you avoid unexpected breakdowns during extreme weather when you need it most.
Many HVAC companies offer preventive maintenance plans designed to keep systems running smoothly and prevent costly breakdowns. What matters most is understanding what's included in each tune-up and how frequently service occurs. At James A. Dalelis Plumbing & HVAC, our comprehensive maintenance programs include thorough inspections, priority scheduling, and service discounts, making it the smartest way to protect your investment and ensure year-round comfort.
