5 Ways to Reduce Allergy Symptoms With Your HVAC System

May 20, 2022

Indoor air may contain contaminants like mold spores, pet dander, or pollen. They may trigger uncomfortable allergic symptoms like runny nose, itchy eyes, wheezing, or itching when you breathe them in. You may have tried different solutions to alleviate your symptoms, including keeping your doors and windows open, to no avail. Your HVAC can help you alleviate or eliminate allergens in your home or business. Heating and cooling systems filter out the pollutants and lower the density of allergens. But if not well maintained, it can blow back the contaminants into the house lowering the indoor air quality. Here are different ways how your HVAC unit can help reduce allergy symptoms. 1. Replace Air Filters Your HVAC unit uses air filters to clean the air getting into your premises. These air filters don’t allow any pollen to enter your house. They also help to clean the indoor air by filtering out contaminants such as mold, dust mites, and pet dander. However, if you neglect air filters for several months, they could become clogged, making them inefficient. Make sure you replace air filters after one to three months. If you have pets at home, do a monthly replacement and use the...

Can Rain Damage Your HVAC System?

April 19, 2022

Can Rain Damage Your HVAC System? Most air conditioning systems rely on two units to get the job done, one installed indoors and another outdoors. The most common concern with house owners is if rain affects the air conditioning unit installed outside. Read on to learn more! Can Rain Damage Your AC? The concern of rain damaging your outdoor HVAC unit is a valid one. Fortunately, the units are designed to be exposed to different weather elements, so rain does not pose a significant threat.

Essential Space Heater Safety Tips

February 15, 2022

When your furnace or radiator isn’t producing enough heat, you may rely on a space heater to keep you warm. Space heaters are convenient, inexpensive and can thoroughly heat smaller areas like bedrooms or the living room. Many families bring out their space heaters once winter begins, relying on these small, efficient devices to keep utility bills down. Following proper safety protocols when using a space heater is essential to the safety of your family and home. Shop Responsibly Space heaters provide a cheaper alternative to entirely relying on your home’s heating system. However, you should still shop responsibly to ensure the heater won’t break prematurely or short-circuit. Avoid buying the least expensive option available, instead opting for a reliable brand that has a thermostat and protection against overheating. You may also be interested in an auto-off feature in case you’re liable to fall asleep when it’s on. Know how to maintain and properly use the space heater before purchase to avoid creating a potential fire hazard. Set Up Correctly Space heaters should sit on level surfaces at least three feet away from any flammable materials. Elevate your heater if you have small children or pets in the home. Follow...

9 Steps to Follow When Cleaning a Furnace or Heat Pump

January 12, 2022

Cleaning the furnace is a significant component of a home maintenance project. A dirty furnace or heat pump is less effective and consumes a lot of energy. Cleaning it well lengthens its lifespan, prevents regular costly repairs, and lowers the utility bill. Here are the steps to follow when cleaning the heating and cooling system of a residential or commercial property. 1. Shut Down the Heating and Cooling System Always ensure that the fuel system and electrical power are off before you start cleaning your furnace. Failure to turn them off can lead to electrocution and serious injuries. You can find the red power switchplate near the burner or on the cellar stairs. The fuel shutoff valve is near the incoming gas pipe or oil tank. 2. Clean the Combustion Chamber The combustion chamber is likely to accumulate a lot of dirt because it provides a space for the fuel to mix with adequate air and ignite to generate heat. This process also leads to the excretion of carbon dioxide, soot, and water vapor that can corrode the chamber walls if they build up. Use a small wire brush to scrape the dirt or an industrial shop vacuum to remove...

Tracking Down the Cause of Your Heater’s Burning Smell

December 20, 2021

Fire is a risk that should be taken seriously by every homeowner in San Antonio. That’s why it’s natural to be concerned when you notice a burning smell coming from your furnace. By better understanding your furnace, you’ll be able to get a good feel for whether or not you should be concerned when you encounter this disconcerting odor. Here are a few tips from to help put your mind at ease. How a Furnace Operates To understand the potential cause of a burning smell in your furnace, it’s important to understand how your furnace operates. When your thermostat calls for heat, the heating cycle initiates. First, if you have a gas furnace, the draft inducer will turn on, ensuring that any harmful gases stay out of your living area. Then, the burner will ignite, firing up the heat exchanger. When the heat exchanger reaches the correct temperature, the blower fan will turn on, pushing cold air over the exchanger so that the temperature of the air rises as it’s distributed throughout your home. Any of these individual components can potentially have a malfunction that can lead to a burning smell. New-Season Shock By far, the most common cause of...

All About the Thermostatic Expansion Valve

October 20, 2021

A thermostatic expansion valve is a device that controls the flow of refrigerant gas in refrigeration and air conditioning systems. It does this by regulating the pressure inside your system. This, in turn, regulates the temperature of your home or office building. The best thing about these valves is that they are designed to handle extreme weather conditions easily, whether it’s blistering hot or cold outside. How Does a Thermostatic Expansion Valve Work? The thermal bulb sensor on a thermostatic expansion valve is designed to sense the temperature of cooling water. As the incoming tap water starts to cool, it contacts the bulb sensor and begins transferring heat from its surroundings into itself until equilibrium has been reached between both systems. When this happens, a wax pellet inside of the thermal bulb expands or contracts according to the amount of energy dissipated for equilibrium. This movement of internal components within an expansion device will cause needle valves within its structure to move accordingly, allowing more fluid through with the exact amount needed. The thermal bulb releases less heat as more cold water flows through these internal structures. This allows pressure to build up behind them while also increasing flow rates...

Signs You Need to Replace Your Furnace

September 20, 2021

Furnaces are often overlooked by many homeowners. Since these appliances are typically hidden away from your line of sight, they often don’t get the TLC that other appliances are accorded with. A well-oiled furnace, however, is synonymous with comfortable indoor temperatures during periods of extreme weather. To help you determine if your heater needs replacing, here are some signs to watch out for. Nearing Its Max Lifespan The traditional residential furnace is designed to last for 15 to 30 years. You can maximize your heater’s lifespan by hiring a certified and insured HVAC technician, like those at , to perform scheduled maintenance and minor repairs every year. However, if you moved into a new home that has a furnace that was installed at least 15 years ago, it’s highly recommended to look for a potential replacement. If your current appliance is gas-powered, the lifespan might be closer to 20 years instead of 30. It’s best to look at modern electric-powered furnaces as a replacement since they can last for up to 30 years or more with regular maintenance. Generating Loud Noises If your furnace is generating perceptible noises during standard operation, it indicates a mechanical problem under the hood. Depending...

How Do the Professionals Install an AC Unit?

August 18, 2021

When you’re looking to replace an old air conditioner or install an entirely new one, you may be curious about what goes into installing the system from beginning to end. You may be surprised to learn that there are a lot of steps involved, and the process itself isn’t easy! Here, we’ll list the general steps in order to let you know what to expect. 1. AC Home Estimation Before any physical work can be done, a professional AC installer will first come to your house and estimate what size unit will work best for your home. Sizing is probably the most important step, though, because an AC system that is too small will work harder than it needs to and use more energy to cool a home, while one that is too big will cool a house too quickly, then have long periods of shut-off, which will actually not keep the house’s temperature consistent. During this step, you will also get a first idea of the cost for your new AC unit and be given an estimate of how much time installation will take. 2. Initial Safety Checks When installers arrive at your home on the first day of...
