Question Answers

What's the fastest way to prevent my HVAC pipes from freezing in a Boston winter?

If you suspect a risk of freezing, call us immediately for emergency service. Our technicians can perform a system check, apply professional-grade insulation to vulnerable pipes, and ensure your furnace is operating at peak efficiency to maintain safe temperatures. For prevention, we recommend a pre-winter maintenance visit to identify and address any weak points before the deep cold sets in.

How can I improve the air quality in my older Boston home?

Older Boston homes often have drafty windows and accumulated dust that affect air quality. We recommend starting with a professional duct cleaning to remove allergens and debris. From there, we can install advanced air purification systems, like HEPA filters or UV lights, directly into your HVAC system to actively clean the air circulating throughout your home, tackling local pollen, dust, and humidity issues.

My system is running but my house is still cold. What could be wrong?

This is a common issue in Boston, especially with older systems. The problem could range from inadequate insulation and drafts—common in historic homes—to a furnace that's not producing enough heat due to a faulty component or need for calibration. Our diagnostic service will pinpoint the exact cause, whether it's a HVAC repair, a recommendation for better insulation, or a discussion about system upgrades for improved efficiency in our climate.
