What does HVAC stand for?

HVAC stands for Heating, Ventilation, and Air Conditioning.

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!

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.

Should I be concerned about carbon monoxide poisoning?

Carbon monoxide is odorless and tasteless and can be potentially fatal. Even if the levels are not enough to be fatal, it still can lead to serious health risks. The most common cause is a malfunctioning central heating system due to being installed without the proper safety concerns or an old heating system that is failing. Conducting regular maintenance by a licensed HVAC technician is recommended and will alleviate any health concerns. It is advisable to install a carbon monoxide detector in your home. The detector should be located in a central location of the home or ideally adjacent to every living area. If you have any doubts about the safety of your heating system please contact a reputable and licensed HVAC company right away to have your system inspected.

What is the proper humidity level?

The recommended humidity level should be 35% but anything between 30% and 40% works best for most homes. If your home rises above those levels condensation can occur and your home becomes a prime breeding ground for mold and other allergens. Dust mites, the leading cause of allergies, thrive in as little as 50% relative humidity. Allergens like molds thrive in relative humidity conditions above 60%, leading to a variety of ailments including asthma, allergies and respiratory infections.

What is an AHRI-certified system?

AHRI is the abbreviation for the Air-Conditioning, Heating, and Refrigeration Institute, a trade association representing manufacturers of heating, cooling, water heating, and commercial refrigeration equipment. AHRI is an internationally recognized advocate for the industry, and develops standards and certifies the performance of many products.
In the case of an air conditioner or heat pump, an AHRI-certified system confirms the performance ratings of specific combinations of the outdoor unit, indoor unit, and/or furnace listed in the AHRI Directory of Certified Product Performance. AHRI’s voluntary certification programs conduct third-party laboratory testing to confirm performance ratings. The ratings associated with such combination are certified in the form of an AHRI Certificate of Product Ratings.
