Nothing means more to us than a customer who feels they were treated honestly. Michele was only in town for a short time, and we made sure she was taken care of quickly, with no pressure and nothing she did not need. That is the Killian's way on every single call. If you want an AC company in St. Pete that shoots straight, we are here for you.

Honoring the men and women who gave everything for our freedom this Memorial Day. 🇺🇸

To the families who carry that weight every day, thank you.

Wishing every Pinellas County household a safe, peaceful long weekend. The cookouts, the beach trips, the pool days, all of it is well-earned.

If your AC decides to take the holiday off, we will not. We are running same-day service across Pinellas all weekend, Memorial Day included. Your family stays cool, the cookout stays on.

How often should you change your AC filter?

In Florida, more often than the package says.

Most 1-inch pleated filters claim 90 days on the box. That number assumes an average home. Pinellas County is not average. Between humidity, pollen seasons, sand from the beach, and pets, your filter clogs a lot faster.

Here's what we tell our customers:

1. Standard 1-inch pleated filter, change every 30 to 45 days during AC season
2. 4-inch media filter, change every 6 to 9 months
3. Pets or allergies in the home, check at 30 days and swap if it looks loaded

A clean filter is the cheapest preventive maintenance you can do. It protects the blower motor, keeps the evaporator coil clean, and trims your electric bill. Skipping it is how a $20 filter turns into a $400 service call in July.

Pop yours out today. If you cannot see light through it, swap it.

Real customers, real results. 🙌

"I am absolutely thrilled with the service from Killian's Air Conditioning. Killian's did an A/C repair for us which was great, then a complete new unit and handler when our A/C died. From the moment I first called, they were fantastic."

Thank you, Jackie. Glad we could keep you cool through it all.

Whether it is a quick repair or a full system replacement, we treat every Pinellas County home like our own. No pressure, no surprises, just solid work and a system that runs the way it should.

Hurricane season starts June 1. Your AC needs a plan too.

Most Pinellas homeowners stock up on water and batteries but forget the system that runs 24/7 keeping their family comfortable. Here's a quick prep checklist:

1. Trim branches and clear debris around your outdoor unit. Anything within 2 feet can become a projectile.
2. Know where your AC disconnect is. If a storm is coming, shutting it off at the disconnect protects the compressor from power surges.
3. After the storm, do not turn it back on until the unit has been checked for water intrusion or debris damage.
4. Schedule a pre-season tune-up now. Catching a weak capacitor or low refrigerant before peak summer beats waiting on a service call in 95 degree heat.

We are booking storm-prep tune-ups across Pinellas County right now. Same-day service when we can.

Your AC is trying to tell you something. Here are 3 signs it needs attention before summer hits:

1. It's blowing warm or lukewarm air. Could be low refrigerant, a compressor issue, or a dirty coil.

2. You hear unusual sounds. Grinding, squealing, or banging means something is loose, worn, or failing.

3. Your electric bill jumped but nothing else changed. Your system is working harder than it should to keep up.

Catching these early saves you money and prevents a full breakdown in July when every HVAC company in town is booked solid.

If any of these sound familiar, a quick tune-up can usually fix it. We offer same-day service across Pinellas County.

St. Pete's already hitting 86 this week. And it's only April.

Before your AC is running full blast all day every day, here's one thing you can do right now: change your air filter.

A dirty filter makes your system work twice as hard, drives up your electric bill, and can lead to a breakdown right when you need it most.

Takes 5 minutes. Costs a few bucks. Saves you a headache in July.

If it's been a while since your last tune-up, now's the time. Before the summer rush hits, we're booking spring maintenance appointments and can usually get to you same day.
