Q: What does HVAC stand for?
A: It stands for Heating, Ventilation and Air Conditioning.

Q: What regular maintenance do HVAC systems need?
A: Your air conditioning and heating units need to maintain unrestricted air flows. You must keep all filters, heat exchangers and coils free of dust, dirt and debris. A maintenance check for your heating and cooling system is recommended twice a year; ideally a spring and autumn tune-up.

Q: How do I know if my system is working properly?
A: Check for strange noises and assess the time it takes to cool down or heat up. You should also see if it is cooling or heating all areas of your home sufficiently. Check if your utility bills have been rising for no apparent reason. Any of these are signs that you might have a problem that needs JMJ Air Conditioning and Heating services.

Q: How do I know if my HVAC unit is big enough?
A: Before purchasing an HVAC system, you should always make sure your system is sized properly to match your needs and budget. JMJ Air Conditioning and Heating provides on-site assessment prior to the installation or replacement of your HVAC system. We have the expertise to determine the proper unit size for your home or business place.

Q: At what temperature should I set my thermostat?
A: Temperature settings depend on the time of year and your personal preferences. In the summer, the average temperature setting is 75 to 80 degrees while in the winter, it is 68 to 72 degrees.

Q: How can I reduce my energy costs?
A: You can adjust the temperature 5 to 8 degrees down in winter or up in summer. You should not block vents in well-used rooms for even air distribution. However, you should close vents in less-used rooms.  You can also install a programmable thermostat to control your home’s temperature when you are away or asleep. It would also be better to upgrade your old air conditioning system to a high-efficiency system in order to reduce energy costs.

Q: How will I know if my HVAC unit needs to be replaced or repaired?

A: If your unit is 7 years older, fails to heat or cool areas of your home, constantly turns on and off, produces high utility bills, then it is more practical to replace your existing system.
