3 Ways to Stop a Cracked Heat Exchanger

Monday, February 1st, 2016

A cracked heat exchanger in your furnace is a serious problem: so serious that if you spot it, you need to shut down your heater immediately and call in a repair service. The good news is that our winters are usually mild enough in San Antonio, TX so that it’s not a catastrophe in most cases, but it can still leave you in the lurch. Sadly, there’s not a whole lot that can be done once the exchanger is cracked. The damage can send toxic gasses leaking into your home whenever you run the furnace. A good heating service can replace the cracked heat exchange with a better one, but you can also take steps to stop a cracked heat exchanger before it starts. Here are 3 ways to accomplish that: each of them easy to do, and capable of saving you a lot of heartache down the road.

Signs You Need to Repair Your Heat Pump

Friday, February 28th, 2014

Heat pumps are a great way to take care of two comfort problems at once: heating and air conditioning. They are particularly good options in Texas because they produce high levels of cooling to match a standalone air conditioner, and they won’t struggle with our mild winter weather.

Because heat pumps are complex devices that rely on mechanical parts, they can malfunction and wear down to the point that they need repairs. Even if you’ve kept your heat pump well-maintained, you may still expect an occasional need for heating repair in San Antonio, TX. When that happens, trust to the work of the staff at Cowboys Air Conditioning & Heating to help you repair your heat pump to full capacity.

Here are a few signs that your heat pump needs our help:

Icing Along The Coils

If you notice ice developing along either the indoor or outdoor coils, you heat pump is in danger of losing its ability to do heat exchange, which will leave you without heating and cooling. You can’t just scrape the ice off—it will come right back. You’ll have to call up heating technicians to investigate and see if the problem comes from a leak in the refrigerant, dirt along the coil, or some other problem that is restricting the coil from absorbing a sufficient amount of heat.

Clicking and Grinding Noises

Loud, strange sounds from any mechanical device is rarely a good sign. If you heat a clicking noise—usually during start-up—it usually indicates that one of the capacitors is failing. The capacitors are responsible for transmitting the electrical charge to the motors to start them running and keep them running. The capacitor will need replacement. Grinding points to failing motors, either worn down by age or dust, and they will also need to be replaced.

Heat Pump Stays in One Mode

If your heat pump will only blow cool air when you want heat, or only blow hot air when you need cooling, then it’s likely the crucial reversing valve that allows the unit to switch functions has broken. There are other possible reasons, such as a broken or miscalibrated thermostat, for this trouble, so call for professionals to diagnose and solve the problem.

To help avoid these problems, make sure that you have signed up for a maintenance program to keep your heat pump tuned-up, adjusted, and cleaned. A yearly visit from an expert in heating repair in San Antonio, TX will help your heat pump have a longer life with few malfunctions.

Cowboys Air Conditioning & Heating offers speedy repairs, 24 hours a day, when your heat pump has trouble. Give us a call today and schedule an appointment. Make sure you sign up for our preventive maintenance agreement to get the most value from your heat pump.

Heating Repair Because of Rust

Sunday, December 22nd, 2013

Rust is the result of a reaction between iron and oxygen combined with moisture from water or air. This reaction creates the red iron oxides that we know as “rust.” Given enough time, rust can chew away almost any iron or iron-alloy and turn it into flakes. You obviously do not want rust getting into the metal of your heating system and causing damage that will lead to repairs and eventually the need for a replacement system.

When you notice any issues in your heating system because of rust or other corrosion, call for repairs right away. Cowboys Air Conditioning & Heating is ready to serve you 24 hours a day with emergency heating repair in San Antonio, TX. Don’t wait for rust to cause you even greater problems.

Common heating repairs because of rust

  • Replacing cracked heat exchangers: Although it may sound odd that a gas-powered furnace, which doesn’t use water to create heat, can develop rust, it can occur because of the reaction between combustion gas and the metal of the furnace. This rust should occur slowly, however. If the furnace has poor ventilation, or if leaks from an air conditioner seep into the furnace’s cabinet, the process will speed up and result in a dangerous situation: cracks developing in the heat exchangers. These cracks can release carbon monoxide exhaust, which is toxic and an explosion hazard. Rust along the inside of a furnace needs to have professional attention immediately.
  • Cleaning the burner: The burner in a gas furnace is where the gas jets ignite to create the heat that will raise the temperature of the air. If rust develops along the burner, it can restrict the flow of oxygen and prevent the jets from turning on. A rattling or booming noise often indicates this problem developing. Experts will need to detach the burner unit and remove the rust.
  • Heat pump repairs: Heat pumps produce condensation and water vapor as they operate, so rust can occur inside them and affect different components, such as the reversing valve, the motors, and the evaporator coils. You cannot have rust anywhere inside a heat pump or it will severely affect the system’s performance. Professionals will need to replace the rusted parts.

Rust is one of the biggest warning signs you can encounter with your heater; don’t “tolerate” a “little bit” of rust when you see it on your furnace, heat pump, or any other heating system. The rust will only continue to grow until the damage turns catastrophic. Call our heating technicians to find out why the rust has started, how to get rid of it, and how to prevent it from returning.

Common Heating Repairs Caused by a Clogged Air Filter

Friday, November 1st, 2013

A common way to heat and cool a home is through a central air conditioner and furnace that share the same set of ducts. Both of these systems use air filters to capture dust, dirt, and other debris in the air to prevent them from entering the cabinet and damaging the components.

During the heating season, you should change out your air filter at least once a month so it doesn’t become excessively clogged. A filter with too much debris contamination can lead to serious trouble that requires professional repair. We’ll list a few of the more common repairs that HVAC technicians have to perform on furnaces because of air filters that have gotten too choked with dust and other contaminants.

If you need heating repair in Canyon Lake, TX, for any problems due to a clogged air filter, trust Cowboys Air Conditioning & Heating. We also offer a Preventive Maintenance Agreement that will help you avoid needing these repairs in the future.

Cleaning the burners

A clogged air filter will do a poor job of preventing dust from getting inside the furnace cabinet. If dirt begins to spread across the burners of a gas-powered furnace, it will cut off the oxygen required for the pilot light and the gas jets to ignite. This means you won’t get any heating at all.

Fixing fan blades

Whether you have a furnace or a heat pump, you’ll need fans to distribute your warmed air. If debris enters the cabinet because of an air filter clog, the damage could bend the blades of the fans. Because the fans are precision instruments, even small kinks in their blades will lead to them striking the housing—a problem that must be addressed right away.

Replacing burnt-out motors

The multiple motors inside a furnace will have to work harder if they become coated with dust and grime. This will lead to them wearing out faster and possibly burning out, requiring that they get replaced.

The simplest step you can take to make sure that you won’t have these sorts of problems from a clogged air filter is to change the filter regularly. However, it’s never too late to sign up for preventive maintenance if you’ve let the air filter go for too long without getting swapped out. Contact Cowboys Air Conditioning & Heating to sign up for our maintenance program. And if you have need for heating repair in Canyon Lake, TX, we can handle that as well.
