Common Questions

Why are my heating bills so high in Haverhill, and what can Smart Oil and Gas Heating do to help?

High heating bills in our climate are often caused by older, inefficient heating systems working overtime or systems in need of maintenance. Smart Oil and Gas Heating can perform a detailed efficiency assessment of your oil or gas furnace or boiler. We offer expert cleaning, tuning, and repair services to restore peak efficiency and recommend high-efficiency system upgrades that can significantly reduce your fuel consumption and monthly costs.

I have ice building up on my outdoor HVAC unit. Is this a serious problem?

Yes, significant ice buildup on heat pumps or other outdoor units in Haverhill can indicate a problem with the defrost cycle or refrigerant levels, reducing efficiency and potentially causing system failure. It's important to address it. Our technicians at Smart Oil and Gas Heating are trained to diagnose the root cause, whether it's a faulty component, low refrigerant, or airflow issue, and perform the necessary repair to ensure safe, efficient operation and prevent further damage.

What kind of preventative maintenance do you recommend for Haverhill homes to avoid these common issues?

We recommend a comprehensive annual heating system tune-up before each winter. For Haverhill homeowners, this includes cleaning critical components, checking and adjusting fuel burners for maximum efficiency, inspecting heat exchangers for safety, testing system controls, and verifying proper airflow—all of which combat high bills. For systems with outdoor units, we thoroughly check the defrost cycle and refrigerant charge to prevent ice buildup. Our maintenance plans are designed to catch small problems before they become big, costly repairs.
