It is inconvenient to have your HVAC unit fail on a hot summer day. It’s even worse if you have to wait for a contractor for a few days in the heat. Fortunately, there are some AC issues that you can fix on your own. The most common AC repair is for units that are not cooling properly or at all. Here are a few things you can do on your own to resolve the most common problems.

Examine the Furnace

Before you do anything else, check the furnace to see if the problem is coming from there. Begin by turning your thermostat to the lowest temperature setting in AC mode. Then, check the furnace to see if the fan is activated. Reset the circuit breaker if it does not start. If this doesn’t work, it’s possible that your furnace is to blame, and it’s time to call your favorite AC repair service.

Check the Air Flow

If your furnace is not the source of the problem, the next step is to try the simplest solutions first. Ascertain that your entire system has unrestricted air flow. Are the cash registers in the house open and unblocked? What is the condition of your furnace filter? Is it sanitary? Is it necessary to replace it? Are the condenser coils squeaky clean? Is there any kink in your refrigerant lines, and is your blower fan working properly?

If there is anything obstructing the airflow, do everything you can to restore unrestricted airflow to your system. However, before performing any cleaning or AC repair, turn off the AC and furnace breakers in the main electrical panel, then use a voltage tester on the contactor wires to ensure that the power is truly off. Turn off the gas at the gas valve that serves your furnace if you have one.

Coils for the Evaporator and Condenser

Because of restricted air flow or low refrigerant levels, the evaporator coil may have ice on it. Close the air handler/furnace panel and turn the thermostat from “Cooling” to “Off” to defrost the coil. Then turn on the fan. The coil should be defrosted within an hour or two. If the ice was caused by a blockage in the airflow, you should be fine once you fix that. However, if low refrigerant levels were the cause, you’ll need a professional to come take a look and, if necessary, recharge your refrigerant.

If the outside condenser coil becomes clogged, it can cause your compressor to overheat and shut down. After you have turned off the breakers, you should turn off the power at the air handler or furnace. The disconnect block must then be removed. Clear out the coils. If the air conditioner does not start up properly, it is time to inspect the access panel.

Examine the Access Panel

The first step is to inspect for blown fuses. If you find them, it indicates that the condensing unit may have a faulty component. Remove the fuses and continue with the AC repair. Install new fuses and restart the unit once the repairs are completed.

It’s also important to check the wiring in the access panel, which could be damaged. Remove the panel and turn off the power. Look for broken or chewed-up wire and insulation, as well as any signs of rodents. If you notice any damage, you can repair it yourself if you have the necessary skills, or you can hire a professional.

How do you know if it was successful?

Reinstall the access panel and the disconnect block, then turn on the furnace switch and the circuit breaker to test your AC repair. If the repairs were successful, the condenser fan and compressor should spin. Unfortunately, if your air conditioner still doesn’t work, you’ll have to contact an Austin AC repair service. Sometimes, especially if your HVAC system is older, it is more cost effective to replace it rather than repair it.

Spray foam insulation outperforms all other types of insulation on a consistent basis. Unfortunately, while polyurethane spray foam is effective at both insulating and sealing, it contains ingredients that can have negative health effects if not handled properly. Isocyanates, for example, can cause skin and eye irritation, asthma, lung damage, and other respiratory problems. There are several steps you should take to keep everyone safe, whether you are the applicator, a helper, or an occupant of the building being sprayed.

Spray Foam Insulation Installation

To begin, read the product information for instructions on how to apply the product, as well as safety practices, precautions, and hazards. You can avoid exposure to potentially harmful ingredients if you take all necessary precautions. In addition, based on the manufacturer’s recommendation, determine the safe re-entry time for unprotected individuals.

If you have any breathing problems or health concerns while applying the foam, seek immediate medical attention. Only properly protected individuals should enter the work area once the foam has been applied. Aside from that, fresh air is essential. Make sure you have adequate ventilation. It is critical to avoid chemical exposure while the spray foam insulation cures after it has been applied. To accomplish this, keep the work area closed to everyone for the predetermined amount of time.

Following the application of the Spray Foam Insulation

Read all instructions carefully to determine the exact time required for curing. For two-component, high-pressure spray foam insulation, some manufacturers recommend 24 hours. This is commonly referred to as “professional” spray foam. The curing time for one-component foam, which comes in 12- or 24-ounce cans, can range from 8 to 24 hours. In general, 24 hours should be sufficient for safe re-entry without the use of protective equipment. Rather than rushing this part of the process, it’s best to be on the safe side and wait longer than specified. If this estimate is not found on the product label, contact the manufacturer or supplier for the re-entry time.

Spray foam insulation becomes chemically inactive when properly applied and allowed to cure. However, there are a number of factors that can influence curing rates. Temperature, humidity, improper workplace practices (such as not sealing air vents or shutting down the HVAC system), improper foam mixing, and other poor application techniques can all affect curing times.

Is Spray Foam Insulation a Do-It-Yourself Project?

Spray foam insulation is a simple do-it-yourself project. In this case, homeowners can apply the insulation with spray foam cans or kits. These kits always come with instructions on how to use them. Larger projects, on the other hand, should be handled by professional contractors. There are simply too many factors that could pose greater potential health hazards with a large project. For application, they typically necessitate the use of protective equipment as well as specialized skills.

Most of us are unaware of the significance and benefits of an attic door cover. However, it is a necessary step if you want to reduce your utility bills. The majority of attic doors are uninsulated and have gaps around the perimeter. This exposed entryway allows unconditioned air to escape the attic, reducing the effectiveness of your existing insulation. Installing or upgrading your attic door cover can improve your home’s energy efficiency and lower the amount of money you spend on heating and cooling. So, what exactly is an attic door cover, and how can you tell if you have a good one?

What is an Attic Door Cover?

An attic door cover, also known as an attic tent, acts as an insulator between your living space and the attic. It seals off the entrance to your attic and keeps unwanted outside air out. During the summer, you can prevent hot, allergen-laden air from entering your home by installing a cover. In the winter, it will keep the freezing attic air out. With an attic door cover, your HVAC system won’t have to work as hard to keep your home at a comfortable temperature.

What Makes a Good Attic Door Cover?

A properly installed attic access cover will have an airtight seal and an R-value that is comparable to your existing attic insulation. It will also be durable enough to withstand repeated opening and closing as you enter and exit your attic. You should treat your attic access as you would any other opening to the outside world. If your front door had gaps and was drafty, you’d seal it right away! The same is true for attic access. A 14-inch gap around your attic door can potentially let in the same amount of air as a typical bedroom heating duct. Wow! What a colossal waste of energy!

The Different Types of Attic Door Covers

There are numerous types of covers. Some are constructed with reflective bubble insulation and laminate, while others are constructed with rigid foam insulation and velcro straps, hinges, and zippers. With so many options, you’re sure to find a cover that fits your attic access, preferences, and budget. Brand-name covers are available, including the Attic Tent, Therma-Dome, Laddermate, Draft-Cap, and Attic Zipper. You can also make your own if you consider yourself a DIYer.

Are You Interested in Buying an Attic Door Cover?

It makes no difference whether you choose a specific type or brand of cover, or whether you install it yourself or hire a professional to do so. The most important thing is to completely seal the opening to ensure that it is airtight. Your savings will be determined by your current energy costs and the airtightness of the attic door cover. If you want to install an attic door cover or have any questions, please contact us and we’ll get you started!

Natural insulation products have many properties that set them apart from conventional materials. Overall, their impact on the environment is much less than that of conventional insulation products. All-natural insulation materials are made from renewable plant or animal sources; their manufacturing processes use very little energy; they are safe for installers and pleasant to handle, and they are reusable or biodegradable at the end of a building’s life.

Why burn wood?

Wood is a renewable resource for timber structures, high-grade insulation and as a fuel. It is one of the most important locally-produced and renewable energy sources. It can be obtained in quantity from sustainably managed woods and forests without needing to transport it a great distance. Wood is a natural fuel that grows by converting solar energy. Leaving wood to rot releases as much carbon dioxide (CO2) as when it is incinerated. Read more “Wood fired heating”
