Q  How do I select a contractor?

AWhen selecting a contractor, it is important to know and trust the person coming into your home. You might want to consider setting up a phone interview to ask questions such as:

  • Do they take on projects of your size?
  • Are contractors at this company subject to background checks?
  • Can they give you a list of previous clients?
  • How many other projects would they have going at the same time?
  • How long have they worked with their subcontractors?

Based on the phone interviews, select a few contractors to meet for estimates and further discussion. A good contractor should be able to answer your questions satisfactorily and in a manner that puts you at ease. Ensure that you can communicate well with the contractor you select because this person will be in your home for hours at a time, but don’t let personality fool you. Check with your state’s consumer protection agency and your local Better Business Bureau to make sure contractors don’t have a history of disputes with clients or subcontractors.

Q Does Quality Air Control service both residential and commercial needs?

AQuality Air Control is proud to offer both residential and commercial HVAC services. We are happy to work on any heating, air conditioning, ventilating, maintenance job – no matter the size!

Q What is the average life expectancy of equipment?

A Most systems have a lifetime of 11 years or less. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. If your system is over five years old, you should have a heating and cooling contractor check your system for maintenance or replacement. In addition, in newer homes, many contractors install the cheapest, bottom-of-the-line units available. This may mean these systems will have an even lower life span. To ensure your system has a long and effective life, schedule regular service and make sure you change filters and other replaceable components regularly.

Q How long will my HVAC system last?

AHVAC Manufacturers typically give products a life span of between 12 and 15 years. The key to system longevity is regular maintenance by experienced HVAC professionals like Quality Air Control. With proper care, you can ensure that your air conditioning and heating system can last from 15 to 20 years. Meanwhile, a gas furnace can typically run for up to 25 years.

Q Can I trust Quality Air Control?

AAbsolutely! Quality Air Control has a fully-trained and licensed staff of professional HVAC specialists. We want you to feel comfortable with the people you bring into your home, so we pride ourselves on friendliness, professionalism, and promptness.

Q How do I know which kind of system I need?

A There are essentially three main furnace types available to users. Furnaces can be single-stage, two-stage, or modulating. They cycle on and off depending on where you set the thermostat.

  1. Single-stage is like a stove where the knobs only have one setting: high. Since a single-stage furnace can only be on or off, the result is greater peaks and valleys in temperature, and less energy efficiency.
  1. Two-stage has two settings, high and low. Two-stage furnaces are more popular than single stage because they have a low-burning setting that keeps the heat from dropping too far below your desired point – making them more efficient because they keep the air temperature from varying as much as a single stage.
  1. A modulating furnace is more like your real stove; it can adjust the flame to any point between off and high. It constantly adjusts its flame to try to keep the air temperature constant. In theory, this results in greater comfort and better efficiency.

If you need to maintain or replace your HVAC system, the first step in determining which system is best for you is calling Quality Air Control. Our trained professionals can help you decide which heating and cooling system will be the best fit for your home and your budget.

Q How often should filters be cleaned or replaced?

A We suggest that our customers have the furnace filter replaced at least once every 4 to 6 weeks during heating season and once monthly for air conditioning.
