Learn how to keep your home comfortable, troubleshoot common issues, and make informed decisions about your heating and cooling system. Our guides are written by experienced HVAC professionals.
When your air conditioner runs but fails to cool your home, it can indicate several issues ranging from simple filter problems to serious compressor failures. This is one of the most common AC complaints, especially during hot East Bay summers.
Read moreIf your AC is actively blowing warm or hot air through the vents, the system has a specific issue that needs diagnosis. Unlike units that simply fail to cool, this symptom points to particular problems with the cooling cycle.
Read moreIce forming on your AC unit or refrigerant lines indicates a problem with airflow or refrigerant levels. While it might seem counterintuitive, this freezing actually prevents your system from cooling properly.
Read moreA furnace that fails to heat your home during cold weather is an urgent issue. The problem could range from a simple thermostat setting to a serious component failure requiring immediate professional attention.
Read moreWhen your furnace blows cold air instead of warm, the burners may not be igniting properly or there could be issues with heat exchange. This problem needs prompt attention to restore comfort and prevent system damage.
Read moreUnusual sounds from your heating or cooling system often indicate mechanical problems that will worsen over time. Identifying and addressing these noises early can prevent costly breakdowns and extend equipment life.
Read moreUnexpectedly high utility bills often point to HVAC inefficiency. Your system may be working harder than necessary due to maintenance issues, poor insulation, or aging equipment that's losing efficiency.
Indoor air quality problems can cause health issues including allergies, respiratory problems, and general discomfort. Your HVAC system plays a crucial role in filtering and circulating clean air throughout your home.
Thermostat problems can make your HVAC system unresponsive, cause temperature swings, or lead to inefficient operation. As the control center of your heating and cooling, a malfunctioning thermostat affects your entire comfort system.
Water pooling around your indoor HVAC unit or dripping from the ceiling near the unit indicates a drainage problem or other issue that needs immediate attention to prevent water damage and mold growth.
Short cycling occurs when your AC turns on and off rapidly without completing a full cooling cycle. This wastes energy, fails to properly cool your home, and puts excessive wear on the compressor.
Hot and cold spots throughout your home indicate airflow or system design issues. Some rooms being significantly warmer or cooler than others reduces comfort and may indicate problems worth addressing.
Replace your air filter every 1-3 months depending on usage. A clean filter improves air quality, increases efficiency, and prevents system strain. Check monthly during peak heating and cooling seasons.
Ensure supply and return vents aren't blocked by furniture, curtains, or rugs. Blocked vents cause uneven temperatures, increase energy costs, and can strain your system.
Professional tune-ups catch small problems before they become expensive repairs. Schedule cooling maintenance in spring and heating maintenance in fall for optimal performance.
Set your thermostat to adjust temperatures when you're away or sleeping. Even a few degrees adjustment can reduce energy bills by 10% or more without sacrificing comfort.
Keep at least 2 feet of clearance around your outdoor AC or heat pump unit. Remove leaves, debris, and vegetation regularly. Good airflow is essential for efficient operation.
Most HVAC systems last 15-20 years with proper maintenance. If your system is approaching this age, start planning for replacement before an emergency forces a rushed decision.
