Mascot Mechanical Frequently Asked Questions

Frequently Asked Questions

Mascot Mechanical’s primary goal is customer satisfaction. The following are the most frequently asked heating and cooling questions. If you should have other questions please give us a call at 469-854-8667 and we will be glad to help.

In most cases, your central air conditioning system will give off signs well before it will fail completely.  Here are some to look for:

  • Moisture or leakage around the indoor equipment could indicate a problem with equipment or in the drain line that is there to carry off excessive moisture.
  • Strange grating or squealing sounds could be warning of serious damage, if the unit is not serviced immediately.
  • Unusual smells coming from your vents – a pungent smell could indicate burned insulation in electrical wiring, a musty smell may be caused by mold growing in the ductwork.
  • Poor or uneven airflow – if some rooms get less airflow than others it’s likely a problem with ducting; if all rooms are getting less cooled air it may be a compressor problem.
  • Rising energy bills you can’t otherwise account for.
  • Frequent circuit breaker problems when the air conditioning comes on could indicate a short in the equipment.
  • If the air isn’t as cool as it used to be, even when turned up full, indicates impending system failure.

Sometimes thermostats break and the problem is not with the air conditioning equipment at all. If you notice any of these symptoms, it’s best to give Mascot Mechanical a call at 469-854-8667.

About 10-12 years is normal in North Texas. This is a harsh climate, so regular maintenance is essential to get the most from your equipment. With current utility prices you should consider replacing sooner rather than later. Newer, higher efficiency equipment can help offset increases in electric rates.

Today’s highly efficient central air and heating systems can save as much as 50% on utility bills. High efficiency equipment doesn’t have to run as hard or as often, so it uses less electricity or gas. Because it runs less often it also lasts longer – another cost-saving feature. At today’s utility prices it doesn’t take long to recover the cost of a new air conditioning and heating system. Ask Mascot Mechanical for details, 469-854-8667.

Your air conditioner and electric or gas furnace are parts of a total HVAC system that will work better, longer and more efficiently with all components matched in capacity and efficiency. For example, your new air conditioner will be rated with a specific SEER efficiency rating. Your existing furnace and indoor coil can significantly affect this efficiency because of technology differences and an imbalance in capacity. A mismatched system that mixes old and new technologies diminishes its performance and your comfort. Financially speaking, it’s much less expensive to replace the furnace at the same time, while the installation crew is there.

Seasonal Energy Efficiency Ratio. Think of it as similar to mileage ratings for cars and trucks – a higher number is better. For example, a 14 SEER rating unit will provide about 40% better efficiency than the 10 SEER units installed in most homes in the 1990s. The minimum SEER value permitted by law now is 13 SEER. For even greater utility savings, we offer equipment rated up to 21 SEER.

Most brands of air conditioners are compatible with each other, as long as you ensure that coils and blowers are sized properly. The best way to assure a match is to stick with one brand so you can be certain of the benefits of a fully integrated system.

We start with an energy analysis of your home, measuring windows, checking insulation, ductwork and building materials, as well as a variety of other factors. We also will ask you if there are rooms in your home that are always too hot or too cold, which may indicate a problem with the existing ductwork, which we should be able to correct.

Yes. An oversized system will provide cooling faster, but will not remove humidity adequately. Also, if your ductwork isn’t big enough to match the air conditioner, the airflow will be too slow and you could freeze the coil, and it will cease to work. Size matters

Running the blower continuously may provide better energy management. It uses a little more electricity, but it tends to even out temperatures and ventilation throughout the house. There are other benefits, too. Continuous operation will provide clearer air because it’s filtered constantly. Also, blower motors usually last longer when they’re not repeatedly starting and stopping.

We recommend that you try both ways to see which you prefer. Some new furnaces allow for this and let you use different speeds, depending on whether the furnace or air conditioner is running.

A programmable thermostat can provide greater comfort and lower utility costs by raising and lowering the temperature for you automatically at specific times each day. It could be an especially good investment if you have a fairly regular household schedule.

Indoor air quality is a problem in millions of American homes. the US Environmental Protection Agency documents that indoor air can be as much as 4-to-5 times more polluted than outdoor air. Mascot Mechanical offers whole-house air cleaners to fit a wide range of budgets, including the Carrier Infinity® Air Purifier air filtration system that provides incredibly clean air. It captures and kills airborne pathogens such as bacteria, viruses and mold. For more details, see this EPA Introduction to Indoor Air Quality.

Temperature is the thing most people think of first. It’s important, as is air filtration (see answer immediately above). To that list add humidity and overall system control.

More humidity in winter makes your home feel warmer, while reducing static electricity, dry, itchy skin and damage to hardwood floors and furniture. Conversely, removing humidity in hot months (the job of your central air conditioning equipment) makes the air feel cooler and less sticky.

Overall control of your central HVAC system – thermostats, humidistats, and zoning design – must be adequate to keep temperatures, air cleanliness and humidity consistent throughout the house. Deficiencies in any of these key areas can cause discomfort and operating inefficiencies. Mascot Mechanical has the know-how and equipment to make certain your heating and air conditioning system delivers in all these critical areas.
