How Often Should I Maintain My HVAC? 

Like every other household equipment, the HVAC requires ongoing maintenance. Periodic maintenance reveals current and potential problems and adds years to the service life of the unit. A well-maintained unit operates reliably for years and needs less frequent repairs. Have your technician inspect and maintain your unit at least twice every year (once before the heating season and then again before the cooling season).

How to Tell If I Need a New HVAC?

Here are some signs you need a new HVAC:

• Your HVAC is on its last legs (15 years or older)
• It needs frequent repairs
• High electricity bill
• You hear weird noises and notice unusual odors coming from your HVAC
• Repair costs exceed 50 percent of the price of a new system
• Poor indoor air quality

How Can I Lower My Cooling Costs?

Here are some simple ways to lower your cooling costs:

• Maintain your HVAC regularly
• Install a programmable thermostat. Do not place your thermostat close to a heat source or in a room that receives direct sunlight
• If possible, avoid cooking indoors
• Use heat-emitting appliances such as televisions, laptops and tablets sparingly during the day
• Upgrade your windows
• Use ceiling and portable fans to get the air moving
• Keep blinds and curtains closed during the heat of the day. Leave your windows open at night
• Plant shade trees around your house
• Seal off any leaks

What Size HVAC Unit Do I Need?

To answer this question, we will have to do a Manual J Load calculation. The calculation is done to determine the amount of heating and cooling loads of a home or building. Some factors to consider when doing a Manual J Load calculation are the type and number of windows and their placement, number of occupants, number of exterior doors, and material type and location.
