"Excellent Service! I highly recommend the Capitol Region Plumbing and Heating Services LLC! Avi, and Sean came to my home immediately when I needed their help with bathroom plumbing and a water pump system. They were courteous, knowledgeable, and thoroughly evaluated the problems. Their excellent assessment and quality of work were evident as I looked at their pictures of before and after replacements of PVC pipes for main sewer lines, sink and shower drains, and water lines for the toilet. Also, Avi and Sean installed a new well pump and pressure tank system. They even came to my home on a holiday to assure me that I'd have water. As true professionals, Avi, and Sean are efficient, punctual, and reputable. Their work ethic is commendable and gracious manners are exceptional. This was an incredible plumbing service that everyone expects and appreciates!"

Heating Oil questions, answered by experts

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.
