In North Oxford, we experience the full range of New England weather, from bitterly cold winter nights to surprisingly humid summer days. Your home's comfort and safety depend on a heating, ventilation, and air conditioning (HVAC) system that can handle these extremes without fail. An inefficient furnace or a broken air conditioner is more than an inconvenience; it's a disruption to your life. We provide comprehensive, reliable, and locally-focused HVAC services designed to keep your North Oxford home comfortable all year round. Our commitment is to deliver exceptional workmanship and unparalleled customer service, ensuring your peace of mind no matter the season.
Choosing and installing a new HVAC system is a significant investment in your home. The quality of the installation is just as important as the quality of the unit itself, directly impacting its efficiency, performance, and lifespan. Our certified technicians specialize in seamless, professional HVAC installations tailored to the specific needs of your North Oxford property.
We begin with a thorough consultation to understand your comfort goals, budget, and home layout. Whether you are building a new home, replacing an outdated system, or upgrading to a more energy-efficient model, we guide you through the options. Our installation expertise covers:
Our installation process is meticulous. We ensure every component is correctly sized, connected, and calibrated for optimal performance. We respect your home, maintaining a clean worksite and completing the installation with minimal disruption to your daily routine.

When your heating or cooling system breaks down, you need a fast and effective solution. We understand the urgency of HVAC emergencies, especially during extreme weather. Our team is equipped to diagnose and repair all makes and models of HVAC equipment. We pride ourselves on our ability to quickly identify the root cause of a problem and implement a lasting fix, not just a temporary patch.
Common issues we resolve for North Oxford homeowners include:
Our technicians arrive with fully stocked vehicles, carrying the necessary tools and common replacement parts to resolve most issues in a single visit. We communicate clearly, explaining the problem and outlining your repair options before any work begins, so you can make an informed decision.
The most effective way to avoid unexpected breakdowns and costly repairs is through regular, professional maintenance. A well-maintained HVAC system runs more efficiently, lasts longer, and provides cleaner, healthier air for your family. Our comprehensive maintenance plans are designed to keep your equipment in peak condition, saving you money and stress in the long run.
A typical maintenance visit includes a detailed inspection, cleaning, and tuning of your system. We check electrical connections, lubricate moving parts, clean coils, inspect the condensate drain, check refrigerant levels, and test system controls. This proactive service catches small issues before they escalate into major failures. Scheduling seasonal tune-ups—one for your heating system in the fall and one for your cooling system in the spring—ensures your equipment is ready to handle the demands of the coming season in North Oxford.
