Your Heating and Cooling System Options

There are a number of factors to consider when choosing the right heating or cooling system for your home. For instance, did you know that too large of a furnace or central air conditioner can be just as inefficient as too small of a system? Our service professionals will conduct what’s called a heat load calculation to determine the right tonnage of HVAC system for your home. This is just one of the steps we take in helping you make an informed decision about what type of HVAC system to put in your home. We’re happy to help you explore your options for system types!
  • Heating: Having a fully functioning, efficient heater is imperative in Havertown, PA as well as throughout the Delaware Main Line. We install and service boilers, furnaces, dual fuel heat pumps, and radiant heating systems from leading brands.
  • Air Conditioning: When it comes time for an air conditioning replacement, or even repair or maintenance, you want to work with a team that has expertise in all types of cooling systems. If you’ve always had a central system, an upgrade could do you well. Though you may want to consider an evaporative cooler or even a year-round HVAC system.
  • Year-Round HVAC Systems: Do you need to replace your heater and your air conditioner at the same time? Fortunately, there are highly efficient and effective year-round options for you! A heat pump operates like an air conditioner, except that the refrigerant process can be reversed to both cool and heat your living space. Consider a standard heat pump, or even a geothermal or ductless system. These both operate on heat pump technology, too.

Comprehensive HVAC Services for Optimal Home Comfort

Having an efficiently conditioned home is about more than simply the type of heater or air conditioner you have installed in your Havertown, PA area home. Is your thermostat up-to-date? A Wi-Fi, or Smart, thermostat can help give you more precise temperature control, and allows you to create a heating and cooling program without needing to adjust the thermostat every time you want your HVAC system to cycle on or off.

Walsh Brothers Plumbing and Mechanical Services, Inc. also provides thorough duct services—contact us for duct testing so we can look for any duct leakage you may have. You may actually be losing 30% of the conditioned air you’re paying for through breached ductwork. We provide professional duct sealing, repair, and replacement services, to ensure your HVAC systems are performing as efficiently as possible.
