What Are Some HVAC System Best Practices?

A lot of people ask what’s the best temperature to set your thermostat at, and the answer to that is whatever temperature you’re most comfortable with. Some tips when it comes to the change of seasons is to make sure to change your filters. The thinner, 1-inch filters you want to change every 1-2 months and the thicker, 4-inch filters you want to change at least twice a year. If you have a humidifier with any ductwork coming out of it, there should be a damper attached to it. Make sure that is open in the winter and closed in the summer. If the weather forecast shows cold temperatures coming later in the week, be sure to set your thermostat at a higher temperature than you would usually and leave it there. Don’t let it set back when you leave for work or during the night because it’s going to have a harder time catching up once that temperature drops.

How Often Should I Get My Heating & Cooling System Checked?

One of the valuable services that we offer is annual checks of the system, both heating and cooling. It’s recommended that we look at each at least once a year. As far as before or after the season, it doesn’t matter as long as we’re seeing the equipment at least once a year. Beyond those two systems checks, what we’re trying to do is determine whether or not we can prevent emergency visits. We’re checking capacitors, we’re checking blower motors, we’re also checking the general condition of the equipment. Typically, when we’re doing a system check, we want to be as thorough as possible. When we’re taking our readings, we’re trying to prevent unnecessary calls or emergency calls at the most inopportune time. Of course, regular cleaning is always recommended; changing filters, etc.

What Should I Check Before I Call An HVAC Company?

Often, our customers will ask “what issues do we check on prior to calling for service?” That’s a great question. You should always make sure that your air conditioner or furnace has power, check that the breakers are turned on, and make sure that the thermostat is set correctly. You always want to check to make sure your filters are unclogged. At that point, turn the unit off and make note of any noises or smells. Be sure to give this information to the dispatchers when you call Deljo heating.

How Often Should I Change My Filter?

Although every filter is not the same, on average, most people change their filter every 60 days. If you have a lot of pets, you may want to move this up to 45 days or 30 days. But, on average, at least a minimum of 60 days.

How Often Should I Get My HVAC System Maintenanced?

The simple answer is once a year. Annual maintenance by a professional will extend the life of your equipment dramatically. Every manufacturer recommends the maintenance on your equipment annually to maintain the warranty they have. Now, your equipment doesn’t know what season it is, so if you get your furnace checked in the spring or the fall, it doesn’t matter as long as you get it done once a year.
