Home Heating Services

Falling winter temperatures are a given outside, but they don’t have to be a given inside your home. If you find yourself constantly needing to bundle up inside to stay warm without blowing your budget, give us a call. We perform heating repairs, preventative maintenance, and new installations all with the goal of improving the energy efficiency of your heating system so that you can keep your home warmer without the added cost.

Indoor Air Quality

As home perimeters become tighter to increase energy efficiency, the quality of the air inside homes has decreased. Cooking , cleaning chemicals, furniture, carpet, all contribute to polluted indoor air. Ireland Heating & Air Conditioning carries a wide selection of indoor air quality products that will make your indoor air healthy again. Air cleaners and purifiers remove pollutants, plus UV lights can destroy bacteria and viruses. Air humidifiers improve the comfort of the air inside your home and ventilators bring in fresh air and filter it before combining it with existing indoor air. We have indoor air products that will meet any need you have.

Ductless Systems

Whether you have hot and cold spots in your home, have added on to your home, or finished off an attic or basement, ductless systems are the answer to many situations. Sometimes adding ductwork or additional square footage to an existing system is not possible. A ductless unit or system can address all of these situations. A single unit outside can power up to 4 indoor units. Ductless systems are energy efficient, unobtrusive and include variable speed compressors that keep inside temperatures consistently comfortable.

Aeroseal Duct Sealing

Duct sealing is a valuable tool for preventing leakage of heated or cooled air throughout your home. Most people aren’t aware that up to 30% of their conditioned air is lost to duct leaks. Sealing ducts can have a big impact on the energy efficiency of your central heating and cooling system. Using the Aeroseal duct sealing process is simple yet extremely effective. Particles of sealant are introduced into the ducts as an aerosolized mist. The sealant builds up on any holes and plugs the leaks. Read more about this revolutionary process on our website.


Modern thermostats do much more than just control the temperature in your home. Programmable and smart thermostats help you save money by regulating the temperature in your home according to your preferences, whether it’s different temperatures depending on the time of day or day of the week; or you’ve got areas of your home zoned to shut off when not in use. Advanced smart thermostats let you control your thermostat from your mobile device, provide weather reports, and can control lights, door locks, window blinds and more.

Snow Melt Systems

It’s hard enough dealing with everything that winter brings. With our snow melt system, you can eliminate ice and snow accumulations and ensure a safe sidewalk and driveway for your family and friends. Radiant and hydronic snow melt systems are available. We’ll be happy to explain how each works and answer all of your questions.
