"I recently had the pleasure of working with Middle Water LLC for spray foam insulation on a client's home and was thoroughly impressed by their professionalism and quality of work. The team consistently showed up on time and adhered strictly to the bid they provided, showcasing their commitment to reliability and integrity. Their dedication and work ethic, particularly the impressive contributions from the hardworking Amish labor, were remarkable. Based on this experience, I have confidently referred Middle Water LLC to another client, who is now planning to use their services as well. The excellent job they did, combined with their punctuality and adherence to the bid, make them a standout choice for insulation services. I am so satisfied with their work that I intend to use them for my own home, which I plan to build in the near future. Middle Water LLC has earned my highest recommendation for anyone seeking top-notch spray foam insulation for their home or business."

Heating and Air Conditioning questions, answered by experts

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

When the capacitor fails, the AC unit can’t operate at all. The most common sign is the thermostat forcing the blower to turn on, but it only circulates room-temperature air. The AC unit also won’t make any noise or indication that it’s on. Sometimes, the compressor might hum as it attempts to work, but without any results.

Before a full shutdown, a faulty capacitor can cause your AC to struggle while turning on. The unit might also shut down in the middle of a cooling cycle.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance
