Berwyn HVAC Company for Repairs
Once you catch something out of the ordinary, have our professionals come over to pinpoint the issue and tell you your options for fixing it. In many cases, a repair means the replacement of a minor component. These components may already be in our technician’s truck, so you could get the problem solved without the need for a second appointment. Project estimates don’t come with any obligation to hire the team.

Heating/Cooling Installation Done Right
Installation of heating and cooling systems is no problem for us; we’re a Dave Lennox Premier Dealer and also carry Daikin and Mitsubishi Electric Products. Let’s say you’re building a home and still planning the heating and cooling aspects. The process can go a whole lot smoother with professionals at your side.
Whether you go with ducted or ductless units, the team can show you a wide range of energy-efficient products. You can also think about enhancements like smart thermostats, humidity controls, and zoning controls for ducted, variable-speed units. We can also install boilers and radiant heating systems.
But maybe you’re wondering if it’s time to replace your heating and cooling systems. In that case, always consider the system’s age and any pending repairs.

Ducted heat pumps and gas furnaces have an average lifespan of 15 years. Mini-splits can run for about 30 years. If your system is near the end of its lifespan and needs a costly repair, then replacement could make sense.
Maintenance for Heaters and ACs
At CSL Climate Control Company, our HVAC services include maintenance. Even the newest, most advanced HVAC system will require maintenance every year. Without it, you’ll start facing multiple repairs, and the manufacturer won’t honor its warranty when these arise. Lack of maintenance ultimately shortens a system’s lifespan. In the meantime, you won’t enjoy the most efficient heating and cooling.
While you can perform basic tasks like changing the air filter and the thermostat’s batteries, you’ll need a professional for the rest. Fortunately, a tune-up usually takes only one or two hours to complete. It will start with a visual inspection.
The technicians will then perform various adjustments and minor repairs to the system. They’ll end with some checks for a prompt start-up, smooth airflow, etc. If the unit needs a repair that falls outside the scope of maintenance, you can schedule it at your convenience.
Here are some issues that maintenance can address:
- Dirt and grime buildup
- Motor bearings needing lubrication
- Loose or out-of-balance parts
- A clogged condensate drain line
