HVAC Work in Casselberry: What the Housing Stock Tells Us

Casselberry’s housing is 48.2 percent single-family detached with a median build year of 1983, and just over half the stock went up in the 1970s and 1980s. That is a large population of systems now on their second or third replacement, in homes whose duct systems have never been touched.

The number that sets Casselberry apart is mobile and manufactured homes: 7.6 percent of housing units here, far above Altamonte Springs at 0.1 percent or Longwood at 1.4 percent. That is several hundred homes running equipment that a lot of HVAC companies will not work on.

We work throughout Casselberry, including Sausalito, Deer Run, Lake Kathryn Estates, Sterling Park and Red Bug.

Permits for HVAC Work in Casselberry

Replacing or modifying air conditioning equipment requires a mechanical permit. In Casselberry that goes through the City of Casselberry Building Division, filed through its CitizenServe portal, where the city publishes a flat HVAC permit fee. We pull it as part of the job. A contractor who offers to skip the permit is telling you something about how they work.

What We See Most Often on Casselberry Systems

Clogged condensate drains

Casselberry developed around a chain of more than thirty lakes. High humidity and a high water table make condensate the single most common service call in this area. The float switch shuts the system down to save your ceiling, and the fix is cheap if you catch it.

Mobile home package units and furnaces

At 7.6 percent of the housing stock, manufactured homes are a real part of this market. They take mobile-home-specific equipment with floor duct systems, different return arrangements and different venting requirements. Site-built equipment will not fit and will not pass.

Attic air handlers and corroded drain pans

In the 1970s and 1980s subdivisions the air handler is usually in the attic. Heat and constant condensation attack the coil and the pan. Rust staining on a ceiling below is worth investigating before it becomes water damage.

Capacitors after storm season

A failed run capacitor means the compressor or fan motor hums but will not start. It is one of the cheapest parts in the system and one of the most frequently used excuses to sell a new one.

Manufactured Home HVAC, and Why Some Companies Decline It

Manufactured and mobile homes do not use the same equipment as site-built houses. They take mobile-home-specific furnaces and air handlers, the duct system usually runs in the floor rather than the attic, the return arrangement is different, and the clearances and venting requirements are not interchangeable with residential equipment.

Plenty of contractors simply decline the call, or quote a site-built system that will not fit and will not pass. We service these homes. If your Casselberry home is manufactured and you have been told nobody works on it, that is worth a second call.

The other Casselberry constant is water. The city developed around a chain of more than thirty lakes and ponds, including Lake Howell. High water table and high humidity are hard on condensate drains, drain pans and attic-mounted equipment, and clogged condensate lines are the single most common service call we take in this area.

Commercial HVAC and Refrigeration in Casselberry

The SR 436 and US 17-92 corridors through Casselberry carry a steady base of restaurants, convenience retail and small commercial tenants. Refrigeration and rooftop work here is mostly small-footprint equipment where downtime is immediately expensive.

Roberts Mechanical handles commercial HVAC and refrigeration alongside residential work, including rooftop units, walk-in coolers and freezers, ice machines, DOAS equipment, cooling towers and chillers. The same repair-first approach applies: we evaluate what a system has left before anyone signs off on a capital expense.

Common Questions From Casselberry Customers

Do you work on manufactured and mobile homes?

Yes. Mobile home equipment is not interchangeable with site-built residential equipment, and a lot of companies will not take the call. We will.

My AC shut off and there is water near the air handler. What happened?

Almost certainly a clogged condensate drain, which is the most common AC call in this part of Florida. The float switch shut the system down to protect your ceiling. It is a cheap fix now and an expensive one later.

What does an HVAC permit cost in Casselberry?

The City of Casselberry publishes a flat HVAC permit fee on its Building Division page, and all fees are paid online through its CitizenServe portal. We pull the permit as part of the job.

What is the flat HVAC permit fee for?

Casselberry publishes a single flat mechanical permit fee rather than a sliding scale. It covers the permit and the inspection. We pull it and schedule the inspection as part of the job.

My home backs onto a lake. Does that affect the equipment?

Humidity load is higher and condensate volume is higher. It makes drain maintenance more important and it makes outdoor equipment corrosion worth watching, particularly on coil fins.

How fast can you get here?

We run 24/7 emergency service. Call 407-405-2658 and we will tell you honestly when we can be there rather than quoting you a window we cannot hold.
