The Effects of Hot Weather on Your Air Conditioner and How Your System Deals With Those?

When the temperature rises in the mid-summer, your AC system takes extra workload to maintain a comfortable indoor temperature. Plus, the longer you run your AC system, the higher the electricity bill you need to pay. But there are other effects of the summer heat on your AC system. Let us take a more detailed look at AC systems vs. hot weather conditions.


As the outdoor temperature rises, your air conditioner works harder to keep your indoor environment cool and comfortable. When the outdoor temperature touches the scale of 100 degrees Fahrenheit, you may notice that your AC system is having difficulty maintaining the comfort of your home. Sometimes, your AC may even fail to reach your comfort level of cooling. Setting the temperature level to achieve the desired temperature is not recommended, as it can reduce the lifespan of your air conditioning system.


The humid climate is uncomfortable to live in, and it also impacts the lifespan of your air conditioner. As there are more water droplets in the air, the cooling system needs to work harder. The air conditioning system can’t cool the water droplets directly. Thus, it needs to go through the air and water particles to cool the right ones. Due to humidity and extra strain on your air conditioner, the lifespan gets reduced, and there are higher chances that your air conditioner may require frequent repair and servicing. Using a dehumidifier, in addition to using an air conditioner, will help you control the humidity. If you are facing any trouble with your air conditioner, you may call for an AC contractor in Roanoke.

Temperature Inconsistencies:

You may feel varying temperature levels in different rooms at your home during the summer. Even when you are setting the AC temperature at the right level to keep your entire house cool, some of the rooms may remain inevitably warmer than others. Places closer to your air conditioning system tend to stay cooler than the rooms at a distance. You can do a few things to control this temperature discrepancy. Portable fans can be the correct device to even out this temperature discrepancy. Closing the vents of your rooms is another way to deal with the problem methodically.

Energy Cost:

Your energy bills are comparatively higher during summers than during other seasons of the year. When your AC must work hard to keep your home cool and comfortable fighting the summer heat, it leads to higher energy consumption. The unit needs to function at its maximum capacity to maintain the desired temperature inside your home, and your wallet will notice its effect. The modern AC companies in Roanoke design their models in such a way so that the homeowner can set the AC unit not to operate above a specific limit. It helps them to save money on electricity bills while preventing the AC systems from overheating.

Susceptible Components:

Most of the internal parts of your air conditioning system can prevent damage because of high heat, as they are designed to handle high temperatures. But some of the components, like the capacitors, can burn due to excessively high temperatures. The heat weakens the outer shell of the capacitor and leads to burning. If your AC is making cracking sound while operating, there is a good chance that your capacitor has been compromised. You may also notice a decreased performance in your air conditioner. You may call an AC contractor in Roanoke and seek maintenance service.

Gas Furnace Buyer’s Guide

Replacing the old furnace in your central heating system with a new more efficient model can offset volatile energy prices. Also, today’s furnaces pollute less and boost comfort by producing heat more steadily than older furnaces.  Gas is the most common heating fuel and here we will focus on gas furnaces.

Over the next several posts, we will cover the most important parts in the process of selecting your gas furnace….

  1. Size matters – The furnace’s specifications should meet your needs.
  2. Efficiency also matters – The efficiency of gas furnaces is reflected in its AFUE
  3. Repair or replace – Depends on what’s wrong and the age of your system
  4. Most and least reliable – Usually when do systems fail? When they are most needed
  5. Features – Each brand of furnace offers a similar array of key features
  6. How to choose your contractor? Key qualifications to look for.

Size Matters!

The furnace’s specifications should fit your needs. Installing a new furnace that’s too small won’t keep your house comfortable during extremely cold weather.

To offset that, the furnaces in most homes are larger than necessary. Initial cost is only one of the drawbacks of that strategy. A furnace that is too large will cycle on and off more frequently. That puts more wear on its components, wastes energy, and might cause the temperature to vary to uncomfortable levels. Also, a larger replacement furnace might require larger ducts. Without the right size ducts, airflow can be noisy.

To be sure of correct sizing and a proper installation, choose a licensed, reputable contractor who will take the time to calculate your heating needs. Such calculations take into account the climate and the size, design and construction of your house.

Efficiency Also Matters!

Gas is currently the most common heating fuel and most new central-heating systems use gas. How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher the number, the more heat the furnace can produce from each therm of gas.

Furnaces have become more energy-efficient over the years. A gas furnace made in the early 1970’s typically has an AFUE of about 65 percent. The lowest efficiency allowed by law for new gas furnaces is 78 percent, and some new models achieve 97 percent.

The price of a new furnace generally rises in step with its fuel efficiency but you can often recoup that additional cost through lower fuel bills over the life of the furnace. How quickly you recover the investment depends on more than just AFUE. The climate where you live, how well your home is insulated, and your local gas and electricity rates also affect payback times.

A Woods consultant can present several models in a range of efficiencies and help you calculate the annual estimated operating cost of each model you’re considering.
