Q: What is HVAC?

A: HVAC is short for Heating, Ventilation and Air Conditioning. HVAC is most oftenused to depict the whole heating and cooling system consisting of the duct work, air filters, humidification controls, and registers.


Q: What regular maintenance do heating and air conditioning systems need? 

A: The most important part of HVAC maintenance aspect is maintaining unrestricted air flows. Dust, dirt, and debris are an HVAC system’s worst enemies. Whether it’s an indoor or outdoor unit, you must keep all filters clean and heat exchangers and coils free of restrictions.

We recommend that your heating and cooling system be checked and serviced twice a year; ideally a spring and autumn tune-up. Also we recommend that you change your filter regularly, depending on the type of filter you have. Changing your filter alone can eliminate many of the common problems that arise, and can significantly reduce the likelihood of a serious breakdown.


Q: How do I know if I have an existing warranty on my furnace, air conditioner or HVAC system? 

A: Locate the label on the outer surface of the equipment for a manufacture date. If the equipment is less than five years old it may have a warranty, but may not as this is based on the model of equipment. Warranty terms and conditions change according to manufacturer and installation company. A+ Plumbing, Heating, & Cooling can verify the warranty status of your heating and cooling system via Get Warranty form.


Q: Why do I need to change my filter regularly? 

A: Regular filter replacement helps your heating and cooling system operate at peak levels and improves indoor air quality. It is important to change filters regularly to ensure proper air flow and to keep your home free from dust, allergens and germs. Depending on the type of filter you have, you may require weekly or monthly filter replacements. Your A+ Plumbing, Heating, & Cooling professional service technician will recommend the ideal filters and replacement schedules for your unit(s).

Q: Is sound an issue for heating and air conditioning? 

A: Yes. Loud heating and cooling equipment contribute to sound pollution. Although no financial savings are tied to lower sound levels, the sound rating of a cooling system can have a considerable effect on comfort and enjoyment of your home. The sound level of an air conditioner or heat pump depends on a variety of factors, such as the age and make of the unit, and whether the compressor is insulated or not can contribute to the amount of noise it makes.

Q: How do I know my heating or air conditioning system needs maintenance? 

A: Is it making strange noises? Is it cooling or heating all areas of your home sufficiently? Has it been taking longer to cool down or heat up? Have your utility bills been rising for no apparent reason? Any of these are signs that you may have a problem that needs service. In most cases, the longer you delay, the worse any underlying problems will get. So be sure to contact A+ Plumbing, Heating, & Cooling services to check out your system whenever you notice anything out of the ordinary.


Q: How do I know if my A/C unit is big enough? 

A: Bigger isn’t always better; its performance and efficiency that count. Before purchasing a replacement system you should always make sure your system is sized properly to match your needs and budget. Your A+ Plumbing, Heating, & Cooling technician will thoroughly assess your home and comfort requirements to determine the proper size and make the appropriate recommendation.


Q: How can I increase the efficiency and life of my home’s heating and cooling systems? 

A: Here are a few quick tips:

- Clean and replace your filters frequently.

- Your system will heat and cool more evenly when the blower is in the “on” position. The blower provides constant air movement throughout the home, and allows for better filtration.

- Install shades, drapes, shutters, or screens on windows that are exposed to extreme sunlight to keep room temperatures at moderate levels.


Q: How can I eliminate indoor odors? 

A: You may have tried to cover up indoor odors by spraying air fresheners or lighting candles. Unfortunately, these tactics only mask the odors, they don’t get rid of them. These remedies may in fact negatively affect indoor air quality from chemicals that cause allergic reactions or eye irritation for homeowners.

Bacteria, dust mites, animal dander, cat saliva and mold may also be roots of your home’s odor problem. Sometimes poor ventilation contributes to unpleasant odors. Moisture condensation on walls windows and stagnate air are signs of poor ventilation. A qualified A+ Plumbing, Heating, & Cooling technician can inspect your home comfort system to determine if this is an issue that should be addressed. The technician can also inform you how to solve the ventilation system’s ability to correctly circulate and ventilate indoor air.


Q: How do I know which indoor air quality product is right for me? 

A: Every person and every home entails a different comfort need. The threshold of irritancy and triggers that affect people’s health and comfort combine to determine the proper solutions. High threshold levels may require simple solutions like a better air filter. Low threshold levels may require an air purification system for the reduction of triggers and irritants. With A+ Plumbing, Heating, & Cooling our professional service technicians can help you decide which indoor air improvement products are right for you.


Q: How healthy is my indoor air? 

A: According to studies created by the U.S. Environmental Protection Agency, exposure to air pollutants indoors can be 100 times higher than outdoors. Frequent dusting and vacuuming can help reduce the amount of dust and dust mites present in your home. However, not all airborne particles can be eliminated. Filtration devices can help eliminate particles that are too small to be caught by a vacuum. Some filtration devices include UV light units, air filters, energy recovery ventilators (ERVs), heat recovery ventilators (HRVs) and electronic air cleaners. Our A+ Plumbing, Heating, & Cooling professionals will provide the information about which indoor air improvement devices are right for you.

Q: At what temperature should I set my thermostat? 

Temperature settings depend on the time of year and your personal preferences. In the summer, the average temperature setting is 75°-80°. In the winter 68°-72° is the norm. Remember, when leaving your house; try to avoid drastic temperature changes. Do not set your temperature at a difference more than 5°; this will cause your unit to work harder to achieve the desired temperature setting.
