We can answer any questions you may have about our services or how these products work. Read a sample of commonly asked questions below.

What does HVAC stand for?

HVAC stands for Heating, Ventilation, and Air Conditioning.

Are there any federal tax benefits to replacing my heating and air conditioning systems to more energy efficient units?

There are significant tax savings when you update your heating or air conditioning units. Here is a link to the federal income tax credits for energy efficiency: https://www.energystar.gov/about/federal_tax_credits. Always check with a tax professional to verify any tax implications or questions you may have.

When should I have my furnace or air conditioner serviced/cleaned?

Manufacturers recommend service and checking of the safety devices be checked on a yearly basis. A gas furnace can produce carbon monoxide and could be dangerous if not vented correctly. The ideal time for your furnace to be serviced is in the Fall, before you turn it on. Air conditioners need to have the refrigerant(R-22, 410A) levels checked to make sure it is operating efficiently. The best time to have you’re A/C looked at is in the Spring. Heat pumps should be serviced in both, the spring and the fall every year.

How often should I change my air filter?

There are many different types of filters. For the standard 1” fiberglass filter, we recommend changing it out every 30 days. There is a washable version of this filter available and instead of throwing it away you should clean it every 30 days. The 1” pleated filter may need to be changed every 3 or 4 weeks. 4” media filters should be changed approximately every 6 months.

How long can I expect my new system to last?

If you have a qualified HVAC technician perform yearly maintenance (serviced/cleaned) as recommended by the manufacturer on your unit, industry averages suggest that an air conditioner last about 12-15 years and a gas furnace should last up to 20-25 years.

Should I change my indoor coil?

If you are replacing your heat pump or air conditioner, then the answer is most likely yes. Efficiency ratings for an air conditioner or heat pump are based on performance as part of a matched system. If only the outdoor portion is changed, the savings and efficiency may be less than that of a matched system.

What is York factory authorized dealer?

Not just anyone can become a factory authorized dealer. Actually, less than 5 percent of heating and cooling professionals in the country receive this distinction. Only dealers who meet their high standards and close scrutiny –not only for technical expertise, but also for business practices and customer service quality can earn this distinction. Here at Wright Mechanical Heating and Air Conditioning we take great pride in being Louisville’s oldest york dealer!

What is MERV?

MERV is an acronym for minimum efficiency reporting value. MERV rating is a scale designed by the air conditioning, heating, and refrigeration institute (ASHRAE) in 1987 to rate the effectiveness of air filters. The scale is a better representation for accuracy of air-cleaner ratings and allows for improved health, reduced cost and energy efficiency in heating, ventilation, and air conditioning(HVAC) systems. For more information about ASHRAE here is a link to their website: https://www.ashrae.org/home. For example, a HEPA filter is often impractical in central HVAC systems due to the large pressure drop the dense filter material causes. Experiments indicate that medium-efficiency filters of MERV 7 to 13 are almost as effective as true HEPA filters at removing allergens, with much lower associated system and operating costs. MERV ratings are from 1-20 with the higher the number the denser the material. For a residential application, MERV 7 to 13 will work best for a home HVAC system.

How often should I change my air filters?

Most manufacturer’s recommend that you change your filters every 90 days but there are few factors to take into consideration. If you have a pet then you should consider changing your filters every 60 days. If you have more than one pet and you or a family member have allergies then every 30-45 days would be best.

What is the life expectancy of my new HVAC system?

If you have a HVAC professional service your system on a yearly basis you can expect your air conditioner to last 10 to 12 years and a gas furnace to last 20 to 25 years.

How do I know what size HVAC system I should have?

There is no rule of thumb when it comes to sizing a HVAC system. There are many variables to take into consideration. Depending on how your house is constructed, a one ton AC unit will cool 300 to 800 square feet. The key is to have a HVAC professional do a load calculation which will take into account all the important factors. Wright Mechanical Services will give you a free estimate to assess your needs. You can count on us to give you an honest assessment on what will work best for you.

How can I improve the efficiency of my heating and cooling system?

Changing your filters and keeping your equipment clean is the best thing you can do. If your equipment is dirty or your filters need to be changed then your HVAC has to work harder to do the same job. Yearly maintenance in the fall and spring is key to keeping your system working efficiently as possible and extends the life expectancy. Instead of throwing it away, you should clean it every 30 days.
