"If you care about the safety of your kids and pets don?t used them for heating and cooling! We hired Apex to install a new furnace and thermostat in December. The installation seemed fine at first. But when we left town for a few days and left the air conditioning on for our cat, we came back to a nightmare. The heat was running at full blast and the house was well over 100°F. It was dangerously hot?this could have killed our cat. This wasn?t a small mistake. It was a serious failure, either in how the system was installed or configured. There was no warning, no alert?just a sealed-up house baking in extreme heat. If you care about the safety of your pets or children, I strongly recommend you do not use Apex for heating and cooling. When I called to report it, they acted like I was an inconvenience. I was told ?someone might call back,? and that was it. No urgency, no concern, no accountability.

Heating and Air Conditioning questions, answered by experts

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

You should schedule a full-service AC inspection at least once a year to ensure it works properly. During this time, your local AC repair pro will check:

  • Safety components, such as carbon monoxide leaks

  • Cooling components, like coolant levels 

  • Electrical components, such as inspecting fuses and wiring

  • Complete system services, like flushing the drain line

While you can DIY some aspects, like changing your air filter, it’s imperative that you call in a pro to inspect your AC for you. Your air conditioner has refrigerant that could be hazardous to your health if not handled properly, so it’s best to let a pro with experience take on this job.

Freon circulates through your AC unit in a closed loop, so ideally, all of it should remain inside your system and never need to be replaced. However, if your AC starts leaking Freon (which is common), you’ll need to top it up. Known as an AC recharge, the cost of adding refrigerant to your air conditioner depends on the size and type of the AC unit, as well as the type of refrigerant.
