Company at a Glance
DiversiTech Corporation, founded in 1971 and headquartered near Atlanta, Georgia, is North America’s largest manufacturer of HVAC equipment pads and a leading supplier of components and accessories for the heating, cooling, and refrigeration industries. Owned by global private equity firm Partners Group since 2021, the company serves over 6,000 customers with approximately 30,000 product SKUs across six product families, including equipment mounting, condensate management, electrical and replacement parts, and HVAC service tools.
DiversiTech’s Six Product Families — What They Make and Why It Matters
DiversiTech does not manufacture furnaces, compressors, or heat exchangers. What they make is the engineering support layer that keeps those expensive components functioning correctly, safely, and quietly over years of operation. Think of DiversiTech as the company that prevents the thousand-dollar problems before they start.
1. Equipment Mounting — Pads, Brackets, and Risers
This is where DiversiTech started in 1971, and it remains their most recognizable product category. An equipment pad is the stable base on which an outdoor air conditioner condenser or heat pump rests. Without a proper pad, units can sink into soft soil, tilt over time, vibrate excessively against the ground, or become surrounded by standing water — all conditions that accelerate component wear and can void manufacturer warranties.
DiversiTech’s flagship line is the E-Lite series: injection-molded polypropylene pads that are UV-resistant, weatherproof, drillable, and engineered with a ribbed understructure that distributes load evenly across soil and gravel. A 36″ x 36″ x 3″ (91 x 91 x 7.6 cm) E-Lite pad weighs only 8.7 lbs (3.9 kg) but handles the full weight of a residential condenser. The ribbed bottom is the key engineering detail — rather than a solid slab, it channels water away and avoids the cracking under freeze-thaw stress that plagues poured concrete over time.
Concrete vs. Plastic HVAC Equipment Pads — How to Choose
| Factor | Concrete Pad | DiversiTech E-Lite Plastic Pad |
|---|---|---|
| Weight | Heavy: 60–120 lbs (27–54 kg) | Light: 8–15 lbs (3.6–6.8 kg) |
| Durability | Excellent, but can crack in freeze-thaw cycles | Excellent; UV and weather resistant; no cracking |
| Vibration Handling | Good mass damping | Ribs absorb and redirect vibration into soil |
| Installation Ease | Requires heavy lifting or pouring and curing time | One-person install; no tools required |
| Drillable for Securing Equipment | Requires masonry drill bit | Yes, standard drill bit |
| Approximate Cost | Higher: material plus labor | Lower; ships via standard delivery |
| Best Suited For | Large commercial units, permanent installations | Residential condensers, mini-splits, pad replacements |
For most residential installations, plastic wins on installation ease, longevity across climates, and cost. Professional HVAC contractors across North America use the E-Lite line as their go-to for residential work.
- Give Your Condenser the Stable Foundation It Deserves — DiversiTech E-Lite 36″×36″×3″ Equipment Pad — UV-resistant polypropylene, ribbed load distribution, drillable. The pad HVAC pros recommend over concrete for residential installs. Rated 4.6/5 stars.
2. Condensate Management
Every central air conditioner and high-efficiency furnace produces water as a byproduct of normal operation. DiversiTech’s condensate management line — pumps, drain lines, traps, treatment tablets, detection switches, and drain pans — addresses every stage of that water’s journey out of your home.
3. Electrical and Replacement Parts
Motors, capacitors, contactors, electrical whips, and disconnect boxes. DiversiTech supplies universal-fit replacement electrical components that HVAC technicians keep stocked on their trucks. These aren’t OEM-branded parts requiring factory ordering; they’re compatible replacement components that restore system operation quickly.
4. HVAC Service Tools
DiversiTech’s tools division — including the Hilmor brand — covers tube bending, tube cutting, refrigerant gauges, sheet metal tools, and service tools used in daily professional HVAC work. These are trade-grade instruments, not consumer hardware products.
5. Maintenance Chemicals and Cleaners
Coil cleaners, drain pan treatment tablets, and HVAC maintenance sprays help maintain system efficiency between professional service visits. A dirty evaporator coil can reduce system efficiency by 20–30%, according to data cited by the U.S. Department of Energy. DiversiTech’s chemical line is one of the most direct and cost-effective ways homeowners can address this.
6. Ventilation Products and Heating Accessories
Duct straps, pipe insulation, lineset accessories, and concentric venting kits for high-efficiency furnaces and tankless water heaters complete the catalog. These products handle the installation and support details that don’t make it into marketing brochures but matter enormously to daily system performance.
Product Families Summary
DiversiTech manufactures and supplies products across six categories: equipment mounting pads and brackets, condensate management systems, electrical and replacement parts, HVAC service tools, maintenance chemicals, and ventilation accessories. Their catalog spans approximately 30,000 SKUs, making DiversiTech the broadest single-source supplier for HVAC accessory parts and maintenance products in North America.
How HVAC Condensate Pumps Work — And When You Need One
This is one of the most commonly misunderstood aspects of modern home HVAC. Most homeowners have never seen a condensate pump, but nearly every high-efficiency furnace or air handler installed in a basement without a floor drain requires one — often it’s the only thing standing between your system running and water damaging your home.
The Simple Science Behind Condensation
When warm, humid indoor air passes across a cold evaporator coil (the refrigerant-chilled coil inside your air handler), moisture in the air condenses into liquid water — the same physics as a cold glass sweating on a humid day. A typical 3-ton (10.5 kW) central AC can generate 2 to 5 gallons (7.5 to 19 liters) of condensate per hour during peak summer humidity. That water collects in a drain pan beneath the coil and must exit through a drain line.
If the drain pan sits above a floor drain, gravity handles everything. But in basement furnaces, many attic air handlers, and any setup where the drain outlet sits below the nearest available drain point, gravity is not enough. A condensate pump lifts that water upward — automatically, continuously, and quietly — to where gravity can take it the rest of the way.
Why the DiversiTech CP-22T Is a Standard on HVAC Service Trucks
HVAC technicians favor the CP-22T for reasons that are visible in the engineering details:
- 22 ft (6.7 m) vertical lift — covers virtually any residential or light commercial installation scenario
- 1.6 gallons per minute (6 L/min) flow rate — handles the condensate output of any residential system
- Three-indicator light system — green (power on), yellow (pump running), red (alarm/overflow) — instant visual diagnostics without guesswork
- Removable check valve — prevents backflow and, critically, allows cleaning without tools; mineral and algae buildup in the check valve is the most common pump failure cause
- Overflow safety switch — shuts down the HVAC system before water escapes the reservoir; budget pumps often omit this.
- Rubber feet and elastomeric motor gasket — minimize vibration noise on concrete floors or utility shelves
Reviewers consistently note units lasting 6–7 years with minimal maintenance, running year-round on both furnaces and dehumidifiers. The removable check valve is repeatedly cited as the feature that sets this pump apart from cheaper alternatives.
- Stop Drain Backup Problems Before They Happen — DiversiTech CP-22T Condensate Pump with Tubing — 22 ft (6.7 m) lift, 1.6 GPM, tri-color status lights, removable check valve, overflow safety shut-off. 4.6/5 stars from verified HVAC professionals and homeowners.
Quick Decision: Does Your System Need a Condensate Pump?
- Yes, almost certainly: Basement furnace or air handler with no floor drain nearby; drain pan outlet lower than the nearest drain point
- Likely yes: Horizontal condensate run exceeding 20 feet (6 m) where gravity flow becomes unreliable
- Probably not: Attic or main-floor system with a drain line running continuously downhill to a floor drain, utility sink, or exterior termination
Condensate Pump Quick Reference
A condensate pump is required when an HVAC system’s drain pan sits below the nearest available drain point. The DiversiTech CP-22T operates at 120V, lifts condensate up to 22 feet (6.7 m) vertically, flows at 1.6 gallons per minute, and includes a built-in overflow safety switch that shuts down the connected HVAC system if the pump reservoir fills beyond its designed limit. The removable check valve allows easy cleaning — the most common maintenance task on any condensate pump.
HVAC Drain Pan Maintenance — The Step Most Homeowners Miss
A clean condensate drain pan and drain line is one of the least expensive, highest-return forms of HVAC preventive maintenance available to homeowners. Yet it’s skipped more than any other routine task. Algae, mold, and mineral scale accumulate in drain pans and lines over a single cooling season, particularly in humid climates — and a clogged drain triggers the overflow safety switch, shuts down the system, and leaves you sweltering until a technician can clear it.
How Drain Pan Treatment Tablets Work
Products like the DiversiTech Pro-Treat 151 contain biocide compounds in a slow-dissolving tablet form. Placed in the drain pan, they gradually dissolve throughout the cooling season, releasing enough active agent to inhibit algae and fungal growth in the pan and the upper drain line. The dosing protocol is straightforward: one tablet per 3 tons of HVAC capacity, placed at the start of the cooling season and refreshed monthly.
The cost-benefit math here is stark. A bottle of 100 Pro-Treat 151 tablets covers a typical residential system for multiple seasons. One HVAC service call to clear a clogged drain line costs far more. Used consistently, treatment tablets prevent the organic buildup that causes the clogs, the musty drain odor that sometimes migrates to vents, and the inconvenient summer shutdowns.
- The $20 Habit That Prevents Expensive Summer HVAC Failures — DiversiTech Pro-Treat 151 Drain Pan Tablets, 100-Pack — Slow-dissolving biocide formula. Stops algae and mold before they clog your drain. EPA-registered and used by professional HVAC technicians nationwide.
Full HVAC Drain and Condensate Maintenance Schedule
| Task | Frequency | Details |
|---|---|---|
| Add drain pan treatment tablet | Monthly during cooling season | 1 tablet per 3 tons of system capacity; drop directly in drain pan |
| Flush drain line with distilled white vinegar | Twice per year (spring startup, fall shutdown) | Pour approximately 1 cup (240 ml) into the drain pan access port; let it run through. |
| Inspect drain pan for standing water or visible slime | Monthly | Any standing water when the system is off signals a partial clog forming |
| Clean condensate pump reservoir and check valve | Annually (spring pre-season) | Remove check valve; rinse with water; confirm float switch activates and releases freely. |
| Clean outdoor condenser coil fins | Annually (spring) | Use a gentle hose spray or no-rinse coil cleaner to improve airflow and system efficiency. |
| Replace or inspect air filter | Every 1–3 months | Depends on filter MERV rating and household dust/pet dander levels |
Drain Maintenance Summary
Regular HVAC drain pan maintenance prevents the algae and mold buildup that causes condensate clogs, vent odors, and system shutdowns. Using slow-dissolving biocide treatment tablets monthly — combined with twice-yearly vinegar drain flushes — is the most cost-effective preventive maintenance a homeowner can perform on a central HVAC system. DiversiTech Pro-Treat 151 tablets are dosed at one tablet per 3 tons of system capacity.
Where to Buy DiversiTech HVAC Products
DiversiTech products are available through HVAC wholesale distributors (Wesco, City Electric Supply, Johnstone Supply, Homans Associates), major building supply retailers (Home Depot, Lowe’s), and online through Amazon and specialist HVAC supply retailers like eComfort. Pricing is generally competitive with or below comparable professional alternatives, and the products are identical whether purchased wholesale or retail.
Many homeowners encounter DiversiTech products without ever seeing the brand name. The plastic pad under their condenser, the compact pump by their furnace, the capacitor an HVAC tech replaced last summer — a large share of those came from DiversiTech’s catalog. The company serves as the underlying infrastructure for North American residential HVAC.

Is DiversiTech a Manufacturer or a Distributor?
DiversiTech is primarily a manufacturer. They design and produce the products in their catalog; distribution occurs through wholesale HVAC supply channels and retail partners. This distinction matters for quality: DiversiTech’s quality control sits at the factory level, not the reseller level. When a technician installs a DiversiTech condensate pump or equipment pad, it was designed and built to specific engineering tolerances by the company whose name is on it.
Do Heat Pumps Need Equipment Pads?
Yes — and arguably more so than standard air conditioners. Heat pumps run year-round in both heating and cooling modes, meaning the outdoor unit and its mounting pad endure every season, including winter freeze-thaw cycles. Plastic pads like the E-Lite series handle this better than concrete, which is vulnerable to heaving and cracking under repeated freeze-thaw stress. A properly installed pad also keeps the unit elevated above standing water and snow accumulation, which is particularly important for heat pumps operating in cold-climate heating mode.
Why Do Modern High-Efficiency Furnaces Produce Water?
Standard furnaces exhaust combustion gases at 300–400°F (149–204°C) — hot enough that water vapor in the exhaust never condenses. High-efficiency condensing furnaces (rated at 90% AFUE or higher) extract so much heat from combustion that the exhaust gases exit at only 100–120°F (38–49°C). At those temperatures, water vapor in the flue gas condenses inside the secondary heat exchanger, producing mildly acidic liquid condensate. This water must be drained continuously during furnace operation — and since these furnaces are typically installed in basements, they almost always require a condensate pump. Installing a condensing furnace without planning for condensate drainage is one of the most common — and most avoidable — HVAC installation errors.
Mini-Split Systems and Outdoor Mounting
Ductless mini-split systems use smaller outdoor units than traditional central systems and are often wall-bracket mounted or placed on compact ground pads. DiversiTech offers mini-split-specific mounting rails, wall brackets, and rubber isolation feet. The core engineering goal is the same as with full-size systems: the unit must be level and mechanically isolated from ground vibration to minimize noise during operation. An improperly mounted mini-split outdoor unit transmits vibration through its mounting surface, making it a common source of low-frequency hum complaints.
What HVAC Maintenance Chemicals Are Worth Using at Home?
For homeowners comfortable with basic maintenance, the most practical chemical products are monthly drain pan treatment tablets (to prevent clogs), annual no-rinse evaporator coil cleaner (applied before the cooling season starts), and outdoor coil cleaner spray (applied to accessible condenser fins). A clean outdoor condenser coil can reduce energy consumption by 10–15%, according to U.S. Department of Energy guidance on air conditioner maintenance. The chemical cost is a fraction of the energy savings over a single season.
Frequently Asked Questions About DiversiTech and HVAC Parts
Who is the parent company of DiversiTech?
DiversiTech is currently owned by Partners Group, a Swiss-based global private markets firm, which acquired the company in late 2021 for an enterprise value of USD $2.2 billion. Before that acquisition, DiversiTech was owned by Permira, a global private equity firm. Permira retained a minority ownership stake after the Partners Group transaction. The company’s management team, led by CEO Andy Bergdoll, has remained in place through both ownership transitions.
What is DiversiTech, in simple terms?
DiversiTech is the company that makes the parts and accessories that support HVAC systems — the pads condensers sit on, the pumps that remove drain water, the treatment tablets that keep drain lines clear, the electrical components technicians replace, and the tools service professionals use on every job. They are not a consumer-facing brand but are ubiquitous behind the scenes of virtually every residential HVAC installation in North America.
How much is DiversiTech worth?
DiversiTech was valued at an enterprise value of USD $2.2 billion at the time of the Partners Group acquisition in 2021. It is a privately held company and does not report public financials.
Can homeowners buy DiversiTech products directly?
Yes. While DiversiTech’s primary sales channel is HVAC wholesale distribution serving contractors, many of its products are also available to consumers through Home Depot, Lowe’s, and Amazon. Equipment pads and drain pan treatment tablets are straightforward DIY items. Condensate pump installation involves a 120V electrical connection and is best handled by someone familiar with basic wiring or by a licensed HVAC technician.
How often should a condensate pump be replaced?
A properly maintained condensate pump typically lasts 5 to 10 years. The most common failure points are the float switch (which can stick if algae accumulates in the reservoir) and the check valve (which can seize with mineral deposits). If a pump runs but doesn’t move water, the check valve is the first component to clean or replace. The DiversiTech CP-22 series features a removable check valve specifically to simplify this maintenance step. Replacing the check valve annually costs a few dollars; replacing the entire pump due to neglected maintenance costs considerably more.
What is the difference between a condensate pump and a sump pump?
A sump pump handles large volumes of groundwater or stormwater intrusion in a basement, typically moving hundreds of gallons per hour at modest lift heights. A condensate pump handles small, continuous volumes of HVAC drain water — typically a few gallons per hour — at higher vertical lifts (up to 22 feet / 6.7 m). They are engineered for completely different flow volumes, duty cycles, and applications. A condensate pump runs frequently in short cycles throughout the cooling season; a sump pump typically runs only in short bursts during heavy rain events.
Does DiversiTech make products for commercial HVAC systems?
Yes. A significant portion of DiversiTech’s 30,000-SKU catalog is designed for commercial HVAC applications — large-format equipment pads, heavy-duty condenser mounting frames, commercial condensate management systems, and electrical replacement components for rooftop units. Their 6,000-customer network includes commercial mechanical contractors, facility managers, and engineers working on large-scale HVAC projects.
How do I know what size equipment pad I need?
Measure the footprint of your outdoor condenser unit (length × width), then choose a pad that extends at least 2–3 inches (5–7.5 cm) beyond the unit on each side. For most residential 2- to 4-ton units, a 36″ × 36″ (91 × 91 cm) pad is the standard fit. A pad thickness of 2–3 inches (5–7.6 cm) is appropriate for most residential soil conditions. Check your unit’s specification sheet or model number lookup for exact base dimensions before ordering.
