Troublesome Signs to Watch for to Help Keep Your Furnace Running Longer

Tuesday, October 31st, 2017

When it’s thirty degrees outside, the last thing you want is your furnace to die. There are several ways to know if your furnace needs repaired or replaced before bad weather arrives. Be prepared for winter with HVAC maintenance and get some peace of mind. Douglas Cooling & Heating will efficiently manage your heating and cooling needs, whether it’s installation of a new system, regular maintenance, or repair work.

Significant Signs:

Regardless of the season, your heating and cooling equipment wears down over time, and frequent HVAC maintenance is required to keep your system in tip-top shape.  You may wonder if there are telltale signs to indicate whether your unit needs a repair or just needs to be replaced. Check out these troublesome signs your furnace may be showing:

  • Dry and dusty: Older furnaces aren’t able to clean your air and add moisture to it like newer models. If your house feels dry or stale during the winter, you may have an issue with low humidity levels. Low humidity creates a dry environment, which makes allergies worse in the winter and allows dust to accumulate more. Investing in a new furnace will help raise your humidity levels and keep your whole family healthy and happy.
  • Age of the system: If your furnace is close to fifteen years old, replacing the unit is better than constant, expensive repairs. Older heating and cooling systems begin to drop in efficiency, and your energy bill will increase. Newer technology offers sadded benefits, like boosting energy savings and saving you money in the future on repairs.
  • Repeated repair work: If your equipment requires frequent repairs, the cost to keep your current unit running might not be worth sinking money into it. Equipment that needs more work becomes less efficient, resulting in higher energy bills. Douglas Cooling & Heating will inspect your unit to determine if the unit is worth the added expense of repairing it or if replacing it would be better.
  • Uneven temperatures: If some rooms in your home are too hot or too cold, you may have leaky ductwork, faulty thermostat readings, or your unit may be going out. The best solution is to call Douglas Cooling & Heating to have HVAC maintenance performed on your system. We will determine if the unit is at fault or if the thermostat needs replaced.
  • Yellow flame: A furnace should have a bright blue flame to indicate that it is running correctly. If your flame is yellow or flickering, you should contact a professional right away. A yellow flame means carbon monoxide could be seeping into your home.
  • Strange noises: Furnaces near the end of their life may begin making weird noises. You might notice squealing, popping, banging, or rattling when your heating and cooling system first starts up or as it runs. Preventive HVAC maintenance performed twice a year could determine if the noises are treatable or if it’s just a sign that your unit needs to be replaced.

Repair or Replace?

If you are experiencing any of the above-mentioned signs and still aren’t sure what to do, call a professional at Douglas Cooling & Heating! Sometimes the repair is small and can be easily fixed with a simple service call. If the problem is much more significant, our technicians will give you options on how much the repair will cost compared to the cost of a new heating and cooling system.

The most important thing is to increase efficiency to save you money. If the unit can be fixed and will operate efficiently for several more years, you should consider repairing instead of replacing. However, if constant repair work is needed to keep your furnace running, you are losing money on frequent repairs and decreased efficiency from your system.

Get the most out of your furnace this winter by scheduling HVAC maintenance to keep it running efficiently. Call Douglas Cooling & Heating for maintenance or if you are in doubt about replacing your current heating and cooling unit. Our NATE-certified technicians are ready to help you save money and energy!

Some Frequently Asked Questions Here At Douglas Cooling & Heating

Tuesday, May 2nd, 2017

WHAT IS THE AVERAGE LIFE EXPECTANCY OF EQUIPMENT?

Most systems have a lifetime of 10 to 20 years. As your equipment gets older, it’s efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show it’s age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. We can estimate the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back in lower energy usage.

CAN I JUST REPLACE THE OUTDOOR UNIT ON AN OLDER SYSTEM TO SAVE MONEY?

No. Replacing only the outdoor unit will lower the efficiency of the unit. In fact, you can lose up to 15% of the unit’s efficiency! Even worse, your system may fail sooner than normal and most manufacturers’ warranties will be voided. You should always replace the indoor cooling coil with the outdoor unit.

WILL A BIGGER SIZED SYSTEM PERFORM BETTER?

No, you don’t want your air conditioner to be too big. Air conditioners control the comfort level in your home by cooling the air and by removing humidity. An oversized air conditioner will cool your home faster, but it will use more energy and will not remove humidity adequately.

A unit that is too big for your home will have short run cycles. It may take only a short time to cool the air, but the unit shuts off before enough air blows across the indoor coil where moisture condenses into water and drains from your system. Too much moisture left in the air can lead to mold and mildew problems.

These short-run cycles also mean your system starts and stops more often which uses more energy and causes a lot of wear and tear. An air conditioner operates more efficiently during long run cycles.

The same holds true for heating systems. An oversized furnace will warm the house quicker, but it uses more fuel and causes greater temperature swings in the home.

WHY IS A SYSTEM WITH MATCHED COMPONENTS SO IMPORTANT?

A matched system is important for a variety of reasons. One is comfort. When all your components are properly sized to your home, you can control exactly how much heating or cooling you need so you can relax. Also, a properly sized matched system enables every component to perform as designed, meaning proper cycle times are maintained, humidity is controlled, and system sound is minimized.

Another reason matched systems are important is efficiency. Most systems people buy are too large for their homes, which uses more energy than needed for your home. A matched system outlined by a dealer who has completed a load calculation for your home provides just the right amount of heating and cooling you need so you get the most value for your utility dollar.

HOW OFTEN SHOULD I CHANGE MY AIR FILTER?

At the risk of telling you something you’re tired of hearing, replace the air filter in your furnace on a regular basis. Dirty air filters reduce the amount of air flowing through a system and make the furnace work harder to maintain the temperature. How often you change the filter depends on the type of filter you use, if you have pets, and the size of your equipment. Please give us a call and we can give you proper guidance.

WHY SHOULD I SWITCH TO A HIGH-EFFICIENCY AIR FILTER?

Proper air filtration is just as important to the health of your heating and cooling system as it is to the health of your family. Without proper filtration, dust and dirt can build up on your system which impacts operation and efficiency. A high-efficiency filter will remove more dust, dirt, pollen, mold, and other particles from the air. If you suffer from allergies or other respiratory problems, you should strongly consider a high-efficiency filter. No matter what type of filter you have – make sure you change it regularly.

SHOULD I HAVE MY FURNACE AND AIR CONDITIONER SERVICED EVERY YEAR?

Yes. Keeping your system properly maintained will lower energy and repair costs, prevent breakdowns, and prolong the life of your equipment. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.

WHY SHOULD I PURCHASE A SERVICE AGREEMENT?

Without warranty coverage, a breakdown can mean significant expense in parts, labor, or both. However, with one of our service agreements, you avoid that unexpected significant expense. While no warranty can guard against every possible problem, we can explain the broad range of protection our service agreements afford.

HOW CAN I REDUCE ALLERGENS AND IMPROVE THE AIR QUALITY IN MY HOME?

With a high-efficiency air cleaner, you can remove up to 99% of the pollen and spores that find their way into the home. There is also a great reduction in household dust, dirt, smoke, and other air pollutants. Your indoor air will become cleaner and fresher while reducing the allergens and dust that circulate throughout the house. With a whole house humidifier, you can relieve the irritating discomfort of dry indoor air. The humidifier reduces itchy skin, scratchy throats, static electricity, and damage to your furnishings and woodwork. Since humid air feels warmer than dry air, you do not have to set the thermostat as high to feel the comfort you want. A lower thermostat setting will reduce the costs of your energy bill.

Tips for Reducing Energy Costs

Tuesday, May 2nd, 2017

Energy costs getting a little too high? Here are some tips that will help you save on your next bill. 

Cooling

  1. Upgrade to a high-efficiency air conditioner – Swapping your old, inefficient air conditioning system for a high-efficient one can cut electricity bills by one-third. Consult one of our professional technicians to ensure your system is the right size for your home, and you aren’t over- or under-cooling for your space needs.
  2. Turn up the temperature – To save electricity during the summer, set the temperature above 75° as every degree below this will add an extra three to five percent to your energy bill.
  3. Install ceiling fans – Change the direction of airflow on your ceiling fans. In the summer, the blades should operate in a counter-clockwise direction as a way of creating a nice, gentle wind.
  4. Have an annual maintenance performed – Having an annual maintenance performed on your air conditioner by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.
  5. Don’t block vents in well-used rooms – Keep your supply and return air vents free of objects like blinds, carpets or furniture so your air conditioner can operate efficiently and there is even cool air distribution.

Heating

  1. Upgrade to a high-efficiency furnace – New high-efficiency furnaces use up to 50% less fuel than an older system. It can save you up to 25 per cent of your home-heating costs in one year, and within a few years, you’ll have recovered the initial cost of replacing/upgrading your furnace. Choosing a model with an energy efficient motor can save 20 to 50 percent of the energy needed to continuously operate a fan motor. Let us show you the advantages of replacing your old furnace today.
  2. Have an annual maintenance performed – Having an annual maintenance performed on your furnace by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.
  3. Install a programmable thermostat – A programmable thermostat enables you to control your home’s temperature when you’re away or asleep. For every 1° you lower your thermostat for seven hours per day, you save one percent on your heating bill.
  4. Don’t block vents in well-used rooms – Keep your supply and return air vents free of objects like blinds, carpets or furniture so your furnace can operate efficiently and there is even heat distribution.
  5. Install ceiling fans – Change the direction of airflow on your ceiling fans. In the winter, the blades should operate in a clockwise direction helping to push the warm air from the ceiling down into the room.
