When summer heat hits homes across Massachusetts and New Hampshire, your air conditioner has a lot of work to do. If your home never feels quite cool enough, or your energy bills climb higher than you’d like, a few simple steps and the right professional support can make a noticeable difference.

Since 2010, Kearney HVAC has helped thousands of local homeowners with cooling issues of every size. Here are some practical ways to keep cool this summer and know when it might be time to think about a home cooling upgrade.

Quick Tips for Boosting AC Performance

There are a few low-cost things you can do to keep your cooling system operating at peak performance throughout the hottest months. If you’ve tried these steps and are still having problems, it may be time to have a professional take a closer look.

  • Keep air filters clean or replace them regularly. 

Dirty filters restrict airflow, making your system work harder and potentially leading to indoor air quality concerns. Check your AC filters monthly during heavy summer use and replace them as needed.

  • Make sure vents and returns are open and unobstructed. 

Furniture, rugs, and closed doors can block airflow and create hot and cold spots. Confirm that all supply and return vents are open and clear.

  • Use your thermostat wisely. 

Aim for a consistent temperature and consider a programmable or smart thermostat to manage schedules and comfort more efficiently.

  • Reduce solar heat gain in problem rooms. 

Close blinds or curtains during the hottest parts of the day in rooms that overheat. This simple change reduces the load on your AC when temperatures are highest.

Professional Maintenance and Service Agreements

Preventative maintenance maximizes summer AC performance, helping your system run more efficiently and reliably when performed year after year. A typical AC tune-up from Kearney’s NATE‑certified technicians includes:

  • Inspection and cleaning of key components like indoor and outdoor units
  • Refrigerant check and adjustments if needed
  • Electrical connections and system control checks
  • Thermostat and airflow checks

For homeowners who want added peace of mind, we also offer service agreements that include routine tune‑ups, priority service, and other benefits to keep your cooling system working at its best.

First-Time AC and Heat Pump Upgrades

Many local homeowners are either replacing older, inefficient air conditioners or adding AC to their homes for the first time. In those situations, upgrading to modern equipment can have a bigger impact on comfort and performance than tune‑ups alone. As part of our white-glove process, Kearney can help you:

Gain access to valuable programs like Mass Save® and NHSaves® incentives. This includes rebates and 3‑year, 0% financing.

Replace aging central AC equipment with properly sized systems that cool more evenly and run more efficiently.

Explore ductless or ducted heat pumps for combined heating and cooling, especially if you’re interested in electrification or dual fuel setups that pair heat pump efficiency with the power of a traditional furnace.

Design a first‑time AC solution that fits how your home is built and used.
