Frequently Asked Questions

May 2021 | New Question:

What is an AC Hard Start Kit and How Can it Help My Utility Bill?

Start Assist Kit is an electrical tool that attaches to the condensing unit of your air conditioner. The extra voltage allows the compressor to start up faster, while using less energy. This can help you save money on your monthly utility bills, prolong the lifespan of the compressor, and more.

Benefits of Start Assist.

  1. Protects the “heart” of your air conditioner

The compressor is essentially the “heart” of your air conditioner. If the compressor is compromised for any reason, the air conditioner won’t function—leaving you without the cool air you want.

  1. Prevents hard starting

Hard starting can lead to short cycling. Short cycling is a huge energy waste and can prevent your home from ever reaching a comfortable temperature. 

  1. Uses less energy.

With Start Assist, your air conditioner won’t have to use as much energy during the startup process. Less energy usage means lower electric bills, even in the hottest months.

  1. Extends your air conditioners lifespan

Replacing a compressor is expensive, in fact, that replacing the air conditioner altogether is generally more cost-effective. Start Assist can ensure that your air conditioner stays in good working order for years to come.

If you’re looking to avoid problems like long term compressor damage, Start Assist is the answer.

How Can You Help Me With Indoor Air Quality?

Poor air quality can affect our family’s comfort and health. So how do we know if we might have a problem? Here are a few warning signs: 

  • ● Unusual and noticeable odor, stale or stuffy air
  • ● Poor airflow
  • ● Dirty or faulty central heating or air conditioning equipment
  • ● Damaged flue pipes or chimneys
  • ● Unvented combustion air sources for fossil fuel appliances
  • ● Excessive humidity/Insufficient humidity
  • ● Tightly constructed or remodeled home (newer & remodeled homes are often sealed better, which has many benefits, but it also means in-home air quality is even more important)
  • ● Presence of microbiological agents
  • ● Health reaction after remodeling, weathering, using new furniture, use of household products, or moving into a new home
  • ● Feeling noticeable healthier outside the home

What is the SEER Rating?

The SEER (seasonal energy efficiency ratio) is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER the more efficient the system will be. The SEER rating of any given unit can range anywhere from 13 to 21.

Why is the SEER rating on the Energy Guide different than what my dealer quoted?

Each split system cooling unit has a nominal SEER rating. This rating can be increased with the upgrade of the same series indoor unit. The SEER rating of a system is derived based on the combination of equipment installed in the home. The outdoor equipment (heat pump or air conditioner), as well as the indoor equipment (evaporator coil and furnace, or air handler), play a vital role in the total rating.

Why should I have regular (or preventative) maintenance? And how often should I have it performed?

Your heating and cooling systems work incredibly hard to perform their functions for your home everyday. The constant stopping, starting and continual operation can wear down any machine if the proper care and maintenance is delayed. However, by performing regular maintenance, you can maximize the lifecycle of your heating or cooling unit and guard against many common equipment failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts that the naked eye may not notice. You should have maintenance done on your system regularly to ensure maximum efficiency and allow prevent possible problems that may occur in the near future.

What equipment requires regular (or preventative) maintenance?

At least twice a year, heat pumps and air conditioners require a professional tune-up. Because gas-fired equipment functions with greater efficiency, they only need to be serviced once each year. Inspections furnace systems should include ductwork, pipes, dampers, valves, the flue pipe, registers, pumps, blowers, gas lines, and every part of the actual furnace. Meanwhile, heat pump and air conditioning unit inspections should also include inspections of the fan, compressor, indoor coils, outdoor coils, and refrigerant lines.

In addition, Trane also provides a network of troubleshooting technicians at Trane Distribution centers across the country which AZ Perfect Comfort will utilize to solve your concern.

What are the advantages of a programmable thermostat?

Since they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.

What type of filter should I use? And how often should I replace it?

Standard filters work to keep your system and its ductwork clean, but they don’t really improve indoor air quality. To do that you need a media filter. The media filter rests between the main return duct and the blower cabinet and will improve dust and particle removal by seven times that of a standard filter. However, upgrading to a pleated media filter will remove everything from insecticide dust to airborne viruses from the filtered air. Always choose a filter that matches your blower’s capacity. For optimum efficiency and filtration, AZ Perfect Comfort recommends that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month.

Where can I get parts for my HVAC system?

AZ Perfect Comfort is the best resource for identifying and supplying the correct, current parts for your system, as well as pricing and availability.

Which HVAC equipment will best fit my home?

There are many factors that affect the sizing and specifications of your system, including square footage, insulation, window surface and configuration, geographic location of your home, duct sizing and arrangement, and many others. AZ Perfect Comfort can perform an in-home load analysis to determine which equipment combinations will perfectly suit your home and your family’s needs. Depending upon the construction of your home, one (1) ton of air conditioning can cool anywhere from 300 to 800 square feet of home. The only way to insure the size of the system you purchase will be large enough to cool your home, but not any larger than you need, is to have your home’s individual heating and cooling needs evaluated by a licensed professional.

What does my warranty cover?

Under the standard factory warranty, most manufacturers cover parts that fail during the warranty period due to defects in the part. The warranty does not cover labor. A warranty certificate was included with your homeowner information packet and is specific to the model numbers, serial numbers, and installation dates of your products. If you cannot find your warranty certificate, AZ Perfect Comfort will also be able to provide you with the information.

What is the life expectancy of my unit?

Dependable Trane products are among the longest-lasting heating and cooling products available. For your specific equipment, there are many variables that affect life expectancy, and of course, the regularity of routine maintenance.
