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.

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...

June 28, 2021

When you start shopping for air filters, you will quickly notice that most products mention something called a MERV rating. What does this mean? Keep reading to find out all about what MERV ratings are and how they work. What Does MERV Stand For? MERV stands for Minimum Efficiency Reporting Value. This is essentially a type of measurement used to determine how good of a job an air filter will do. The MERV scale was initially developed by the American Society of Heating, Refrigeration, and Air Conditioner Engineers (ASHRAE). Over the years, it has been adopted by most major air filter manufacturers who now specifically aim for certain MERV ratings when they produce products. The MERV rating can be a very useful way of comparing filters regardless of their type, size, or materials. The MERV scale runs from 1 to 20, and ratings are assigned based on the size of particles that pass through the filter. Lower MERV levels mean the filter catches less small debris, and higher MERV levels mean it filters more particles out of the air. What Do Different MERV Levels Mean? It can be a little hard to understand what MERV means when you just look...

Top 5 Ways You Can Boost Your Home’s Comfort and Save Money with a Zoning System

December 18, 2020

In a conventional forced-air system, one thermostat controls the temperature for the entire house. But sometimes you only need to use one or two rooms. In those instances, a conventional system will still run and consume the same amount of energy. In this article, we’ll look at how zoning can help save you money and boost your San Antonio home’s comfort. 1. Enhance Temperature Control A zoning system will have multiple air handlers that allow you to control airflow for separate rooms. Every contiguous area has a thermostat that records temperatures that will tell the air handler when to start. That means you don’t have to condition those areas of your home you don’t use frequently. Conventional heating systems will heat all parts of the building simultaneously. Even when you are only using one room, your furnace will keep running. As a result, they end up wasting a lot of energy, which will keep raising your utility bills. 2. Effective Approach to Adding an Extra Room Another benefit of zoning is that some areas of your home may have unique heating and cooling needs. Perhaps some rooms have features such as high ceilings, lofts, or large windows. Such features may...
