We made it through a very cold February, and now many of us are hoping we’ll have an easy shot right to spring. It might happen. Or we might have more cold weather and need our heating systems working for a few more weeks. This is one of the reasons it’s still important to pay attention to your home’s furnace.

We always stress with customers that when a heating system needs a repair, it doesn’t matter the time year it is: the repair must be scheduled as soon as possible. For a gas furnace, it’s especially important because it has the potential to become hazardous if malfunctions are ignored. Even though it’s March, keep an eye out for furnace problems at this time so you can move fast to have them taken care of.

Ways a Faulty Thermostat Can Affect Your Home Heating

Monday, February 8th, 2021

We enjoy mild winters here in Texas, with some occasional cold snaps where we’re thankful to have central heating systems. Because we don’t rely as heavily on our heaters as our neighbors to the north do, we can often coast along with a basic setting on the thermostat during the days and a lower temperature at night and not have to worry about the heating system needing to turn on too often. 

But your heating in San Antonio, TX can start to suffer if the thermostat isn’t working right. Thermostat troubles are often easy to overlook: a homeowner may assume that some of the problems listed below are troubles from inside the heating system itself. This is why it’s important to only call on HVAC professionals when you have heating issues. Our technicians can determine what kind of malfunction is harming your home comfort. If it turns out the thermostat is at fault, we’ll have an easier repair or replacement to take care of that will get your comfort back to normal.

The Impact of a Malfunctioning Thermostat

Thermostats can fail in several ways, from the simplest of manual models to the most complex new smart thermostats with Wi-Fi connections. 

The most common thermostat malfunction is a basic miscalibration. All thermostats have a temperature sensor that reads the air temperature near the center of the house to estimate how warm the building is in general. If the thermostat is miscalibrated, it will either sense the house as warmer or cooler than it actually is, and the house won’t be able to reach your desired temperature. The thermostat will shut the heater off too soon or allow it to run too long. If you find that you’re adjusting the thermostat often when this wasn’t normally a problem, it may mean that the thermostat needs professionals to recalibrate it. (We recommend replacing old manual thermostats that use a mercury sensor; these are out-of-date units.)

A loss of connection to the heater is another problem thermostats have—and it isn’t as easy to diagnose as you might think. Thermostats have multiple wires connecting to the control board of the HVAC system: separate wires to turn on and off the heating system and to turn on and off the blower fan. If one of these wires fails, it means the heater or blower fan won’t respond or won’t shut off. Let a technician determine what’s wrong and how it can be fixed. 

Thermostats can pick up ghost readings that are similar to a miscalibration, except in this case the issue is a hot or cold anomaly outside of the thermostat. If the heating system seems to be turning on and off at odd times, check to see that the thermostat isn’t exposed to a draft (such as an open window) or a new heat source like a lamp or an appliance. A thermostat that was poorly located in the first place may have direct sunlight affecting it. 

No matter the thermostat problem or other HVAC issue that’s hurting your winter comfort, put your trust in our team.

Why Does My Furnace Turn On and Off So Often?

Monday, January 25th, 2021
furnace-isolated-white

During our mild winter months when you run the furnace to keep your household warm, you’ll become used to a standard pattern for how the HVAC system turns on and off. You’ll hear the blower fan come on, then the furnace burners ignite, and the rush of heated air pushed through the ductwork. After fifteen minutes or more, the furnace will then start cycling down, turning off the burners and eventually the fan. When the temperature begins to fall below the setting on the thermostat, the HVAC system will begin another heating cycle.

This is the normal behavior you’re used to from the furnace and probably don’t pay much attention to it. But if the furnace breaks this pattern and begins to turn on and off with greater frequency, you may notice. And then you may wonder: is this a problem?

How a Heating System Can Warn You It’s In Trouble With Sounds

Monday, January 11th, 2021

We can imagine that in the future, home heating systems like furnaces will come with complex computer diagnostics that will allow them to identify malfunctions immediately and then alert you to their existence. They may even be able to automatically call your friendly neighborhood heating repair experts—that’s us!—to get the problem fixed ASAP.

But until that technology arrives, you’ll have to use other warning signs from your heater that will tell you it’s time to call us for heating repair in San Antonio, TX. Today, we’re going to look at one specific type of warning, which is unusual sounds.

If you’ve had your heating system for at least one season already, then you know the sort of noises it makes regularly. When you notice something out of the ordinary, it may be a developing repair problem, even if you haven’t noticed any other change in the heater’s performance.

The Biggest Gas Furnace Worry: A Cracked Heat Exchanger

Monday, November 30th, 2020

Gas furnaces are one of the best ways to provide comfort to a home during any winter season. They are reliable, work fast at delivering heat, and are powerful enough to help drafty and poorly insulated homes get through cold days.

Homeowners sometimes have worries about the safety of using a gas furnace. But if gas furnaces were inherently dangerous, they wouldn’t be permitted in homes at all—and they certainly wouldn’t be the number type of heating system in the country. The modern gas furnace is built with numerous safety precautions. If you make sure to keep up with regular maintenance and prompt furnace repair in San Antonio, TX when necessary, you shouldn’t have to worry about your gas furnace posing any hazards. 

However … we do need to talk about one concern: the cracked heat exchanger.

Why Won’t Your Heat Pump Actually Heat?

Monday, November 16th, 2020

A heat pump is a convenient way to provide comfort to a home since it works as both a cooling and heating system. Changing between the two modes is as easy as adjusting the thermostat. Once colder weather starts in winter, you only need to set the thermostat to a higher temperature and the system will switch over without trouble to begin heating. 

Except—well, no heat pump can work 100% free of malfunctions, so you may find yourself in a situation where your heat pump isn’t changing into heating mode when you need it. It may still send cool air from the vents, or maybe it isn’t sending out air that’s warm enough. What’s wrong, and does this mean you need to call us for heating repair in Schertz, TX?

Now that we’re in the second half of winter, it’s wise to watch for problems your household heating system may experience.

The Guilty Thermostat: When It’s the Source of Winter Discomfort

Monday, January 27th, 2020

When you think of problems with your household heating system, you probably think of the heater unit itself: the furnace or the heat pump. But a heating system is exactly that—a system of components that work together to provide even, efficient, and effective comfort for the house. The system also includes the ductwork, the air handler, and the thermostat.

The thermostat often gets overlooked when homeowners try to figure out why they aren’t getting the comfort they need or why the heater has shut down. But even small thermostat problems can have consequences for comfort and result in an unnecessary climb in monthly utility bills. Fixing, recalibrating, and replacing thermostats is an important heating service in San Antonio, TX we offer.
