Your Plumber and HVAC Contractor Serving St. Johns and DeWitt

How Much Does AC Service Cost?

The cost of your AC repair or installation depends on the layout of your home and the circumstances involved. For that reason, we cannot provide quotes over the phone. But giving us a call is enough to get you scheduled for HVAC service in DeWitt or St. Johns.

How Long Will My AC Unit Last?

While the lifespan of a new AC unit varies based on make and model, most will last between 10 and 15 years. Some systems can last over 20 years if properly maintained. A lot of this, however, depends on how much you use your air conditioner. That doesn’t mean that you should wait for it to break. Old units are often inefficient and expensive to repair. Being proactive about AC replacement in St. Johns is a great way to save money on your utility bills.

Is there Anything I Should Check Prior to Calling?

Before contacting Chasco for AC or furnace repair in the St. Johns area, go through the basics. Make sure you don’t have a dead thermostat or a tripped breaker. Then, put in a new air filter and make sure you have the system set correctly. If none of these things are to blame, reach out to us for a furnace diagnostics check.

How Do I Know If My Furnace Is Under Warranty?

You'll want to start by finding out when your unit was produced. There's usually a visible production label on the machine—the placement of it varies by brand and model. Once you have that, look up the manufacturer's warranty and see if yours falls within eligible dates. Note that some HVAC companies offer their own no-lemon and installation guarantees that go beyond what the factory offers.

How Often Should I Check My Air Filters?

You'd be amazed how many HVAC problems are caused by someone forgetting to change their air filter. If you use a 1-inch disposable filter, we suggest replacing those monthly. For people with a 4-inch system, two changes a year is often enough.

What Do I Do When My Air Conditioner or Furnace Quits?

Why Is My Water Pressure Suddenly Low?

Low water pressure can be caused by clogged fixtures, sediment buildup, a partially closed shut-off valve, or even a hidden leak.

Our team can inspect your system and restore proper water pressure before the problem leads to damage.

What Should I Do If I Have a Plumbing Leak?

If you notice water where it shouldn’t be, shut off your main water supply right away to limit damage. Even small leaks can cause mold, rot, and higher water bills over time. A licensed St. Johns plumber can locate the source quickly and make the proper repair.

How Do I Know If I Need a Plumber or If It’s a DIY Fix?

Minor issues like a loose faucet handle may be safe to fix yourself, but recurring clogs, slow drains, leaks, or water pressure problems usually point to a deeper issue. Calling Chasco for professional plumbing in St. Johns prevents temporary fixes from turning into costly repairs.

Why Do My Drains Keep Clogging?

Frequent clogs often mean there’s buildup deeper in the pipes from grease, soap residue, hair, or even tree roots. If plunging doesn’t solve the problem, it’s time to call a St. Johns plumber for a proper inspection and drain cleaning.

How Can I Prevent Plumbing Problems in My Home?

Routine maintenance goes a long way. Avoid putting grease or food down drains, use drain screens, and address small leaks early. Scheduling periodic inspections with Chasco can help catch issues before they turn into emergencies.

How Do I Know If My Boiler Needs Repair or Replacement?

Signs of boiler trouble in St. Johns include uneven heating, strange noises, rising energy bills, or frequent shutdowns. Older boilers can also lose efficiency over time. Chasco will inspect your system and help you decide whether a repair will restore performance or if replacement makes more sense.

Why Does the Air in My Home Feel Dusty or Uncomfortable?

Poor indoor air quality in St. Johns is often caused by dirty filters, duct buildup, excess humidity, or poor ventilation. If your home feels dusty or aggravates allergies, Chasco can recommend air quality solutions like filtration upgrades, humidifiers, or air purifiers to improve comfort.
