Years ago on our blog, we warned customers about the dangers of purchasing HVAC equipment online. There are plenty of reasons for this, such as getting a system with a voided warranty. A common item people purchase on their own is high-tech thermostats, thinking they can’t go wrong with basic climate controls. Unfortunately, a mismatched HVAC system and thermostat can end up damaging the HVAC system.
But the most important reason to never purchase HVAC equipment online is the issue of sizing. Unless you’re a professional HVAC technician, you won’t know how to properly size a new air conditioner to work correctly for your house. Sizing must be precise. A system that’s too large or too small means years of trouble from an AC that never seems to work right.
When we talk about installation of a new heating, air conditioning, and ventilation system for a house, we often say things like, “If you have a good installation, the new system will save money on energy costs.” Or, “If you have a good installation, you won’t have to worry about hot and cold spots around your home.”
Because the winter season is short and mild in Southern California, it usually isn’t until now (i.e. November) that homeowners start to consider special home maintenance needs for the season. That’s fine—if you haven’t arranged yet for fall HVAC maintenance with our team, it’s certainly not too late for it. Call us to schedule 
Spring and summer both arrive early here in Southern California.
You are hunting for a heating, air conditioning, and electrical contractor for work in your house. You already know that simply pulling a name off of a quick Internet search isn’t the best way to go about making the choice. You want a contractor you can trust not only to get the job done right, but whom you’ll feel comfortable allowing into your house.
