M & R Heating & Air Conditioning - Washington DC's Qualified HVAC Services

DC's humidity can trap allergens and pollutants indoors. We recommend a multi-step approach: first, ensure your HVAC system is clean and your air filters are changed regularly. We can also install advanced air purification systems or UV lights in your ductwork to actively neutralize mold spores, bacteria, and other contaminants, significantly improving your indoor air quality.

Capacitors help start your AC's motors, and the relentless, high-demand operation during our hot, humid summers puts immense strain on them, causing premature failure. The best prevention is a professional preseason maintenance tune-up. We'll test the capacitor's health, clean the system to reduce strain, and identify any electrical issues before they lead to a costly, uncomfortable breakdown on the hottest day of the year.

Our comprehensive maintenance service is designed for our local climate. We thoroughly clean coils and components, check refrigerant levels, calibrate thermostats, tighten all electrical connections (including capacitors), lubricate moving parts, and perform a full safety inspection. This proactive service improves efficiency, prevents common failures, and ensures your system is ready to handle both our humid summers and chilly winters.
