HVAC FAQs


We all rely on heating, ventilation, and air conditioning (HVAC) every day to keep us comfortable. But over the years, HVAC systems have gotten much more complicated. To help answer your most frequently asked questions, Deljo Heating and Cooling, a Carrier dealer in Irving Park, has assembled this list of HVAC FAQs.

When Do I Need to Hire an HVAC Professional?

If you’re not sure, you may as well err on the side of at least calling an HVAC professional to diagnose your problem. You’ll definitely want to call an HVAC pro if you’re replacing, repairing, or inspecting a water heater, air conditioner, or furnace.

Not only will an HVAC professional ensure that all your HVAC issues are handled safely, but he or she will also make sure your HVAC system is running efficiently.

What’s the Difference Between Electric and Gas Water Heaters?

From a functional point of view, electric and gas water heaters are quite similar. The only real difference is the mechanism by which the water is heated. However, where a gas water heater may be as tall as your ceiling and three to four feet wide, an electric water heater can be mounted on your wall. Most of them are about the size of a small suitcase.

How Often Should I Inspect My HVAC System?

Your HVAC system actually consists of many parts, from the ducts to the furnace to the water heater. Each of these components, and more, make up a complete HVAC system. To be safe, you should inspect your HVAC system at least once a year. It’s always a good idea to check on it before winter so you’re not left freezing while you wait for a professional to help you.

When Should I Install a New Furnace?

Furnaces usually last 18 to 20 years if you have it regularly maintained. But if you don’t know how old your furnace is, it can be tough to decide whether it’s time to replace it or not. Generally, if your furnace is constantly breaking down and requiring costly repairs, it’s time to replace it. As a general rule of thumb from Deljo Heating and Cooling, a Carrier dealer in Irving Park, you should replace a furnace if the cost of a repair exceeds or equals 50 percent of how much a new replacement furnace would cost.
