Q&A
What services do you offer for a home addition or expansion?
When adding onto your North Oxford home, your existing HVAC system may struggle to heat or cool the new space effectively. We specialize in creating additional zones for home expansions, installing new air handlers and ductwork to ensure consistent comfort throughout your entire house without overworking your main system. This approach improves efficiency and comfort in both your new and existing rooms.
We're building a new home in the area. Can you handle the full HVAC installation?
Absolutely. With over 35 years of combined experience in residential and commercial projects, we routinely manage large-scale installations for new constructions. Our process includes working with your builder, properly sizing and selecting efficient furnaces, air conditioners, or heat pumps, and installing the complete ductwork and air handling system to ensure optimal performance from day one.
My HVAC pipes keep freezing in winter. What's the common cause in this area?
Frozen pipes are often a symptom of improper HVAC installation or insufficient insulation, issues we frequently correct in North Oxford homes. An undersized system, leaky ductwork, or blocked airflow can cause the evaporator coil to get too cold. Our technicians diagnose the root cause—whether it's installation-related or a maintenance issue like a dirty filter—and provide a lasting fix to prevent recurrence and protect your system.
