When Should I Replace My Thermostat?

Monday, March 21st, 2016

Your thermostat is the brain of your HVAC system, regulating the temperature inside a single room or your entire living space. It works by sensing the ambient temperature and sending an electrical signal to your air conditioning system, furnace, or both, causing it to cycle. Thermostats are fairly reliable devices, but they occasionally run into problems just like any other component of your system. But how do you know when it’s time to replace your thermostat?

3 Common Cooling Issues You May Encounter This Summer

Monday, March 14th, 2016

In an ideal world, you’ll never run into any issues using your cooling system. However, even well-maintained air conditioners need regular maintenance and occasional repairs. Hopefully you don’t face any detrimental issues this summer. However, read on for 3 common cooling issues you might encounter, to help you prepare if you find yourself needing repairs.

1. Your Unit Doesn’t Turn On

There are a couple different factors that may be at play here. Your first instinct may be to call for repairs, and we’ll be happy to help. However, first you should check to see that your thermostat is set in the “cooling” position, and that your system is receiving power. Though these may seem obvious, the fact is that with multiple occupants in the home, settings can get adjusted without your knowing. Of course if your system is still having electrical problems after you’ve checked this, you’ll need the assistance of an experienced HVAC technician.

2. Your Unit Blows Warm Air

Dirty filters are a very common culprit for warm air. It’s not that your AC isn’t producing cold air, but that the cooler air can’t flow through the ductwork properly. Clean air filters will not only help this, it protects the inside components of your AC and helps it perform properly. You should also make sure that the outside unit is running, and that there are no leaves, dirt, or other debris obstructing airflow. One last thing that may be causing warm air to flow through your system is insufficient refrigerant, which a licensed HVAC professional will need to replenish for you.

3. Your Unit Cycles Frequently or Will Not Turn Off

If your AC unit is too large for your home, it will go through a process called short-cycling. This is when it shuts off and on rapidly. This rapid cycling can also occur if an air handler is blowing cool air directly onto the thermostat. On the contrary, if your system won’t cycle off, the unit may be too small for your home. It could also be due to low refrigerant levels or a faulty relay switch. Either of these would need to be repaired by a professional.

Why a Bigger Air Conditioner Is Not Always Better

Monday, March 7th, 2016

If you’re thinking of replacing your air conditioner this year, it’s important to take a few factors into consideration. A common misconception about air conditioning is that a bigger unit will run less and cost less. Think of your AC system like a car: the more you drive your car in stop-and-go traffic rather than the highway, the faster it wears down. Your air conditioner must continuously shut on and off to compensate for its size if it is too big, a process known as short-cycling. This makes your system inefficient.
