What Your Neighbors SAy About Bloch

“Brandon was fantastic. [He] came quickly and replaced the blown capacitor in less than 24 hours! Pricing was fair and easily explained.”

Christopher C.

“I am very pleased with Brandon, the new owner of this family-run company. I had a bad experience on the phone dealing with a different large company in the area, but once Brandon took over, everything went great from start to finish. He saved me THOUSANDS by figuring out that I still had a little bit of time left on a 20-year warranty. I highly recommend this business.”

Jamie H.

FAQs

How Do I Know If My Home Needs a Dehumidifier?2026-06-30T22:00:45-05:00

General mugginess or stickiness is a clear indicator. Other signs include:

  • Musty or stinky odors
  • Condensation on windows
  • Mold or mildew spots in your bathroom or closets
How Do I Know If My Home Needs a Humidifier?2026-06-30T22:00:21-05:00

Common signs of humidity that is too low include:

  • Static electricity
  • Dry skin, chapped lips, and sore throats
  • Wooden furniture or floors that have shrunk
  • Cracking or peeling paint and wallpaper
What Is the Ideal Indoor Humidity Level?2026-06-30T21:59:55-05:00

In general, moisture levels between 30 and 50 percent are perfect. Too low and you could suffer from dry skin and static shock; too high and you could experience mold growth, musty odors, and mugginess.

Can a Smart Thermostat Detect Problems in My Heating and Cooling Systems?2026-06-30T21:58:33-05:00

Yes! Many new thermostats act as a sort of early-warning signal, letting you know if your home’s temperature isn’t right despite constant system operation or if your air filter needs replacing.

What Some Other Features of Smart Thermostats?2026-06-30T21:58:15-05:00

Some thermostats offer geofencing, which uses your phone’s location to automatically adjust temperatures when you leave the house or come back. Other features include energy reporting and easy smart home integration.

Can I Control My Zoning System With a Smart Thermostat?2026-06-30T21:57:56-05:00

Yes! In fact, you can control that zoning system with multiple smart thermostats, as every “zone” in your home will have its own. They communicate seamlessly with one another as well, letting you handle everything straight from your phone.

How Much Can I Save With a Smart Thermostat?2026-06-30T21:57:38-05:00

Though the devices are more expensive up front, smart thermostats enable you to schedule temperature changes and monitor energy usage. In doing so, you can save as much as 15 percent on your utility bills.

Can I Add Zoning to My Existing HVAC Systems?2026-06-30T21:57:05-05:00

Yes! We can retrofit your existing heating and cooling systems—as well as the ductwork they use—to offer zone control throughout the house.

What Are the Main Benefits of a Zoning System?2026-06-30T21:56:39-05:00

One of the biggest is that it provides you with customized comfort from room to room all across your house. Plus, zoning helps reduce your energy usage and reduce wear and tear on your furnace and AC.

Does My Air Conditioner Help With High Humidity?2026-06-30T21:56:03-05:00

It does. However, the best way to reduce moisture levels is to use a whole-home dehumidifier. It removes excess moisture from your air, helping get rid of that muggy feeling—and contaminants like mold that thrive in it. Plus, the lower the humidity, the cooler you’ll feel, meaning a dehumidifier can also improve your comfort even without the AC on.

Is There Anything I Can Do Myself Before Calling Bloch?2026-06-30T21:53:44-05:00

To make sure your system really does need our help, check your thermostat to ensure it’s set to “Cool” and that the target temp is lower than the current room temp. You can also check the circuit box to ensure the breaker hasn’t trip. If neither of those steps help, give us a call.

Why Is My Air Conditioner Blowing Warm Air?2026-06-30T21:53:07-05:00

There could be a few reasons for this. Usually, a failing part or airflow restrictions are to blame. Failing capacitors, low refrigerant, and a dirty condenser coil are among some of the most common culprits.

Can I Clean the AC Unit Myself?2026-06-30T21:51:17-05:00

There are certain tasks, such as clearing away weeds, leaves, and debris from around the AC, that you can do yourself. However, for safety, it’s best to leave the internal servicing to our pros.

What Happens During AC Maintenance?2026-06-30T21:50:58-05:00

Our team cleans and tunes your system from top to bottom, making sure it runs as smoothly as possible. We’ll wash the condenser coil and clear the drain line, measure and test electrical components, ensure proper airflow, and more.

How Often Should I Schedule Service?2026-06-30T21:50:30-05:00

We recommend making a service appointment for your AC once a year, ideally in the spring before the summer heat hits. That way, your system will be ready for the weather and will operate efficiently and reliably.

Should I Replace My Furnace at the Same Time as My AC?2026-06-30T21:49:01-05:00

If your AC needs replacing and your furnace is 10 to 12 years old or older, then yes, we do recommend installing both together. Bundling the installations can save on labor costs and improve your year-round efficiency.

What Is SEER2, and What Rating Should I Look For?2026-06-30T21:48:37-05:00

SEER2—or Seasonal Energy Efficiency Ratio 2, measures the efficiency of a given AC. The higher the number, the more efficient the system. For tighter budgets, aim for a SEER2 rating of around 15.

How Long Does a New AC Installation Take?2026-06-30T21:48:15-05:00

The answer depends on a few factors, including the size of your new unit and the layout of your home. Typically, you can expect an installation to take between four and 10 hours.

Do Ductless Units Work in Winter Climates Like Ours?2026-06-30T21:43:03-05:00

They do. In fact, many of today’s units are designed to work in cold climates. However, they may have a harder time doing so, in which case pairing it with a furnace or boiler can work well.

Where Can I Install a Ductless System?2026-06-30T21:42:38-05:00

Most units are mounted on the wall in the room of your choice. However, some can be installed on the floor as well.

How Many Indoor Units Can Connect to One Outdoor Unit?2026-06-30T21:41:42-05:00

Ductless systems connect to an outdoor condensing unit, which enables the heat transfer. You can connect up to eight indoor units, making for perfect comfort all across the house.

Can Ductless Systems Heat and Cool My Home?2026-06-30T21:41:21-05:00

Yes! In the winter, a ductless system will transfer heat energy from the air outside and bring it in for warmth—and in the summer, the process reverses.

What Are the Main Benefits of Ductless Systems?2026-06-30T21:41:03-05:00

Advantages include energy efficiency, custom comfort room-to-room, easy installation, and quiet operation.

How Do Ductless Systems Work?2026-06-30T21:40:29-05:00

These small, wall-mounted units transfer heat energy from the outdoors to both heat and cool your home. They are an ideal solution for houses without ductwork, additions, and garages.

Should I Repair or Replace My Aging Boiler?2026-06-30T21:38:15-05:00

When you call Bloch, our priority is to get you as much time out of your current system as possible, which means we aim to repair first. But if that fix is too unsafe or costly—or if your system is 15 to 20 years old or older—it’s in your best interest to replace the system.
