Professional Filter Replacement in Preston, Cary

Most HVAC systems don't die out of nowhere. They fail because small problems — a dirty coil, a weakening capacitor, low refrigerant — go unnoticed year after year until something expensive breaks. A $3,000 compressor failure, a cracked heat exchanger, a coil eaten through by corrosion — all of it preventable with annual maintenance that costs a fraction of what the repair bill looks like. The average HVAC replacement in the Triangle runs $6,000 to $12,000, and most of those replacements happen to systems that were never maintained. That's the math. Element Service Group's maintenance plans exist to keep you on the right side of it.

What HVAC Maintenance Includes

Maintenance breaks into a few categories. Annual maintenance plans are the backbone — you sign up once, and we schedule your spring AC tune-up and fall heating tune-up automatically. No remembering, no missed years. Each visit includes a full system inspection, cleaning, calibration, and a written report on your equipment's condition.

Spring AC tune-ups get your cooling system ready before the Triangle's first 90-degree week hits. We check refrigerant levels, clean the condenser and evaporator coils, test the capacitor and contactor, and make sure the system is cycling properly. Fall heating tune-ups do the same for your furnace or heat pump — checking the heat exchanger for cracks, testing safety controls, cleaning burners, and verifying carbon monoxide levels.

Filter replacement, preventive maintenance visits, and full system inspections round out the category. Some of this you can do yourself. Some of it you really shouldn't.

Why Maintenance Plans Pay Off in This Climate

Triangle HVAC systems work harder than most. Your AC runs heavy from May through September — we regularly hit 95 degrees or higher in July and August — and your heating kicks in from November through March. That's 8 to 9 months of the year where your system is under load. Homes in Apex, Cary, and Holly Springs that were built during the 2000–2015 boom are running original equipment that's now squarely in the breakdown zone.

Duke Energy customers in Wake County see summer electric bills push past $200 a month. A poorly maintained system can add 15–25% to that number. Dirty coils alone can reduce efficiency by 30%. A $200 maintenance visit that saves you $40 a month on energy and prevents a $2,000 repair pays for itself multiple times over.

Plan Benefits Beyond the Tune-Up

Element Service Group's maintenance members get more than two visits a year. You get priority scheduling — which matters in July when every AC company in Raleigh-Durham is booked out two weeks. You get discounts on repairs. And you get the peace of mind that comes from a veteran-owned company with 700+ five-star reviews standing behind your equipment year-round.

We also track your system's history. Each visit builds on the last, so we can spot trends — a capacitor that's weakening, refrigerant that's slowly dropping, a blower motor drawing more amps than it should. Catching those trends early means you replace a $150 part on your schedule instead of a $3,000 part on the system's schedule.

The Satisfaction Guarantee

If you're not happy with a maintenance visit, we make it right. It's that simple. The plan is month-to-month with no long-term contracts you can't get out of. We keep members because the value is obvious, not because the cancellation process is complicated.
