Heating and Air Conditioning on the Same Day

San Diego Winter Problem #3: HVAC Confusion

Why do I have to choose?

Your HVAC system (heating, ventilating, and air conditioning) gets really confused during the harsh San Diego winter. The "Heating" part of your system is actually used (really) for about 30 minutes each morning to "take the chill off" and yet, around 2:00pm, it is back to "Cooling" mode as that bright sun streams through your picture windows. 

Yes, it is almost always 74 degrees here in San Diego, but glass windows heat up interiors like a greenhouse unless you keep your windows open (but that's another topic). Anyway the real problem is that most thermostats force you to manually choose between heat and cool, which when done twice a day makes you feel like a cave man calling on the HVAC gods to do his bidding! Urg. Now. Um. Heat. Now. Cool. Mmm! 

Luckily, technology has started to get past this, and modern thermostats like the Nest Learning Thermostat will automatically handle the mode switch for you. Thank goodness for small miracles! Together, as a united humanity, we will overcome!
