Trusted HVAC Services in Portsmouth, VA 23707 - Don Jones Heating And Cooling

It depends on the age and condition of your unit. For older systems (10+ years) struggling in our humid summers, a replacement with a modern, energy-efficient model is often more cost-effective long-term. For newer units, a repair might be all that's needed. We can diagnose the issue—common culprits here are refrigerant leaks or failing compressors—and provide an honest recommendation for the most efficient and economical solution for your home.

Thermostat malfunctions are frequent in our area due to power surges and humidity. Issues can range from incorrect temperature readings to a complete system failure. Our preventative maintenance plans include checking and calibrating your thermostat, ensuring all electrical connections are secure, and cleaning components to prevent dust buildup. This proactive service helps avoid sudden breakdowns, especially during peak summer or winter seasons.

For our climate, proper sizing (load calculation) is critical—an oversized or undersized unit won't cool efficiently or control humidity. We recommend systems with higher SEER ratings for better energy efficiency and models with strong dehumidification capabilities. Our installation process ensures optimal airflow and correct refrigerant charge, which are key to a system that delivers reliable, powerful cooling through the hottest Virginia days.
