Question Answers
My air conditioner in DC isn't cooling well and my bills are high. What should I do?
This is a common issue for DC homes, often caused by an aging system, refrigerant leaks, or dirty components. Allied Service Company can provide a thorough HVAC inspection to pinpoint the inefficiency. We'll check your refrigerant levels, clean coils, and assess the system's overall health. Often, a professional maintenance service or a strategic repair can restore efficiency and lower your bills. If your system is old and frequently failing, we can discuss replacement options that are better suited to our local climate and your home's specific needs.
Do you handle hot water recirculation pump installations for older DC homes?
Absolutely. Installing a hot water recirculation pump is a great solution for older DC residences where plumbing runs can be long, eliminating the wait for hot water at the tap. Our licensed plumbers are experienced in retrofitting these systems into existing homes. We'll assess your plumbing layout, recommend an appropriate pump, and perform a clean installation that provides immediate comfort and can contribute to water savings, making it a practical upgrade for many local homeowners.
