Signs You Need Commercial Heating Repairs

Monday, December 28th, 2015

If you’re a business owner in the Corpus Christi area, you must take special care during the winter that your building’s commercial heating system remains in the best shape. We don’t experience brutally low temperatures over the season—not compared to cities such as Chicago and Minneapolis—but the outdoor temperatures can still fall to levels that will make the inside of your establishment uncomfortable for your employees, clients, customers, tenants, etc. Watch for signs that the heating system, whatever type it is, is starting to fail so you can call on commercial HVAC professionals right away.

Some Heat Pump Malfunctions You Might Encounter This Winter

Monday, December 21st, 2015

Heat pumps are becoming more popular for homes every year as the technology behind them advances. If this is your first winter using a heat pump to provide your household with warmth, you may want to pay special attention to it to see that it is running correctly. Although heat pumps are built to last for around 15 years, they can still encounter repair problems along the way that will need fast attention from professionals. Below are some of the more common malfunctions a heat pump may encounter over the winter. (more…)

Should the Pilot Light Flame Be a Color Other Than Blue?

Monday, December 14th, 2015

Gas furnaces are still the predominant way that homes stay warm through cooler weather. Many gas furnaces no longer use a standing pilot light to ignite the burners that create hot combustion gas. Instead, they rely on intermittent pilot lights (which turn on only as needed thanks to an electric spark) and hot-surface electronic ignition systems (which operate entirely on electricity, no pilot light needed).

Help! My Heat Pump Won’t Switch to Heating Mode!

Monday, December 7th, 2015

We’re starting to experience colder evenings now in the Corpus Christi area, and we can also expect cooler days ahead as we move into winter. For many of you, this means switching your heat pump over from cooling mode to heating mode. The ease of making this change is one of the biggest advantages that a heat pump provides.

But what if your heat pump won’t stop cooling? If you change the thermostat so that the heat pump sends out hot air, but you don’t receive any warmth from it, then there could be a number of problems. Here are the two most common:

Thermostat malfunction

It’s possible that the thermostat is at fault, not the heat pump itself. If a thermostat loses its connection to the reversing valve (see below) in the heat pump, it won’t be able to change the system from one mode to another. A temperature miscalibration could also be responsible. Whatever the case, you’ll need to have an HVAC technician look into the thermostat and repair it. In some cases, it’s simply better to upgrade to a new thermostat with improved features so you can get the best service from your heat pump.

Broken reversing valve

The key component that makes a heat pump a heat pump (as opposed to a standard air conditioner) is the reversing valve. This valve is attached to the refrigerant line that exits the compressor, and it directs the refrigerant in one of two directions. Depending on the direction, the heat pump will be in heating or cooling mode. If the valve breaks and gets stuck in one position, the heat pump will not be able to switch modes. To fix this, professionals will remove and replace the reversing valve.
