HVAC Tune-Ups Provide Savings Year Round

With Texas weather as hot as it is in the summer, your AC unit has to work extremely hard. Be prepared for those hot and humid summers of Katy. Performing an AC tune-up annually will increase the lifespan of your AC unit and ensure it won’t stop working when you and your family need it the most. All air conditioning companies are extremely busy during the summer months, and the last thing you want when your AC is broken is to wait hours or days before a company can see to your issue. You can keep many significant problems from happening by getting an air conditioning tune-up every year. These tune-ups can help your AC unit operate at or near original factory specifications, and end up saving you thousands of dollars on repairs. The increased efficiency and longer lifespan of your unit will make you glad you got a tune-up.

Best Rated 24 Hour AC Repair

Living in Texas, your AC unit will be working nonstop during the summer months, and oftentimes, at many other times throughout the year. Sadly, if these units work too hard for too long they could stop working. If that happens, you’ll want to get the issue seen to as soon as possible for the sake of you and your family’s comfort. But don’t contact just any company, make sure you contact a company you trust to repair all your issues for you. Air conditioning systems often experience a vast range of varying issues, and you’ll need a technician that is knowledgeable in order to rectify the situation. If your AC unit needs to be repaired, trust a certified and licensed technician from Abacus to find the problem, figure out how to solve it and repair it. Call today to get the best HVAC professionals in the business to fix any and all of your AC problems in an efficient and timely manner.

Air Conditioning System Replacement

Anytime your air conditioning unit malfunctions, you have the choice to either repair or replace it. Energy Star suggests replacing your AC system if it is over ten years old. However, other issues such as consistent fluctuation in temperature, noticeably high energy bills, or a halting in operation completely, may suggest you need to upgrade your system. Whenever you face expensive repairs, you should consider if replacing will be a better and more affordable option. Abacus has certified and licensed HVAC technicians that will be glad to inspect your AC system and see if a repair or replacement will be a better option for you.

Insulation for Your Attic Keep Heating And Cooling Cost Low

All homeowners want to lower the cost of their monthly energy bill, but many don’t know that the easiest way to do this is through attic insulation. Your house could be showing signs that it needs new attic insulation. Such indicators can be frequent temperature changes in your house, wet insulation, indoor drafts, or significantly high energy bills. Replacing your attic insulation can help to maintain the temperature in your home so that it is warmer in the winter and cooler in the summer. Houses that have good attic insulation have furnaces and air conditioners that work efficiently and, in turn, save on energy costs. Installing attic insulation is not a do-it-yourself kind of job. Call a certified and licensed HVAC company to make your house more comfortable and help you save you money.

Quality Matters With Thermostats

Many homeowners are surprised to discover the value of their thermostat. Thermostats have one of the most important jobs in your house. A great thermostat should be able to steadily keep your home cool or warm, all while saving you money. Most AC experts recommend a programmable thermostat that can lower your energy costs through the use of scheduling. With a schedule in place, you can set your thermostat to increase the temperature when you leave and to decrease it when you get home. Great thermostats last many years, but eventually, they all have to be replaced. An upgraded thermostat will increase the comfort of your home and lower your overall costs. When it’s time to replace your thermostat, Abacus will be happy to help you decide which thermostat is right for your house and install it.

Air Duct Cleaning Services For Your Home

Air duct maintenance often falls through the cracks for many homeowners. Unfortunately, that means so does the air quality in your home. As air ducts get dirtier, they can begin to accumulate mold, bacteria, and fungi that prevent air from flowing freely through your ventilation system. This makes your ventilation system work a lot harder, and in turn, cost you more money monthly. An intensive cleaning of your air ducts can save you a lot of money over time, and improve the overall air quality in your home. We recommend you get a licensed air conditioning company do your air duct cleaning for you.

Reliable Air Duct Installation & Replacement

It can be difficult for homeowners to decide whether they need to clean or replace their home’s air ducts. While many times air duct cleaning is enough, eventually you’ll need to replace your air ducts to completely do away with any problems. Old air ducts can have significant damage that prevents your ventilation system from operating efficiently. If your AC unit is not operating correctly then it will cause higher costs on monthly energy bills. An immediate sign that you should replace your air ducts is if they have ever had mold. In many cases, mold can be completely removed from metal ducts, but plastic ducts must be replaced to get rid of all mold. It’s recommended that you replace your air ducts if your house is over 50 years old, or if there is any extensive damage that can’t be repaired. Getting air ducts installed is not a do-it-yourself type of job. Consult Abacus, a certified and licensed HVAC company and have your new air ducts installed today.
