Why is it Always Hot Inside My House?

Why is it Always Hot Inside My House?

Are you constantly asking why it’s always hot inside your house? If your house always feels too warm in the summer, no matter where you set the thermostat, it could be the size of your HVAC unit. Bigger isn’t always better. Take a look at why the wrong-sized system could be the reason for your hot house this season.

When the Unit is Too Big

It’s easy to think that bigger is better when it comes to cooling your house, but that’s not usually the case. If you get a too-big AC unit thinking it will make for a super-cool house, you’re in for an unpleasant surprise. If there’s too much tonnage, it will cycle on and off frequently to meet temperature demands. Because of the size and the short cycles, it cools quickly but can’t reduce the humidity, leaving your home feeling too warm and a bit sticky. You’ll also find the temperatures are inconsistent because longer cycles lead to more dependable cooling.

When the Unit is Too Small

Homeowners that choose units that are too small for their home’s square footage have similar issues for opposite reasons. A system that doesn’t have the size and power to cool off your home in regular cycles will run longer and still not meet demand. It will use more energy in the process of trying to keep up, raising your utility bills, and it still won’t be able to keep your house cool.

If your house feels too hot this summer, it could be your HVAC system is the wrong size. For help finding the solutions, contact the team at Hill Plumbing and Air.

Tankless or Tanked Water Heater: Which is Best for Me?

Water temperature controls on a hot water heater

For decades, the only option for water heaters was the old standard – the tank system. Now you have the option to go tankless. How do you know which is best for you? Let’s take a look at some of the features of tankless or tanked water heater systems.

Tank System

A traditional water heater consists of a tank that holds 30-50 gallons that heats water and stores it until you turn on the hot water faucet.


  • Inexpensive to buy and install, usually between $500-800
  • They’re easy to replace
  • Newer models are much more energy-efficient than older versions


  • A large amount of space is required
  • They use energy keeping the water in the tank warm whether you’re using it or not
  • They can run out of hot water and take time to refill and to heat more water

Tankless System

Tankless water heaters are an on-demand system, only heating the water as you need it instead of storing it in a tank and reheating it over and over until you use it.


  • Highly energy-efficient and last twice as long as a tank unit, with a life expectancy of up to 20 years
  • They don’t take up a chunk of space
  • Tankless systems don’t run out of hot water, heating it only as you need it


  • More costly than tank heaters, tankless equipment is about twice the price
  • They require expensive and more extensive installation and often even require retrofitting of older homes to accommodate all of the components
  • You might have output issues, as the on-demand process can only heat a certain amount of water at a time

If you’re still uncertain about which way to go for your hot water needs, never fear – the team at Hill Plumbing and Air has got you covered. Contact them today to find out everything you need to know about water heating systems.
