What Our Customers Say

Frequently Asked Questions


As the seasons change, it’s important to keep your home at a comfortable temperature. A home that is too hot or too cold can cause problems with allergies, headaches, and other health issues.


Your heating and cooling system also helps to keep your home safe by monitoring the temperature inside your home and adjusting accordingly. If you notice that your HVAC system seems to be working on its own, this means that your system has detected a problem with temperature regulation and is trying to fix it.


The best time to have your heating and cooling system serviced is at the beginning of the season before you need it. If you wait until the middle of summer, for example, and your AC starts acting up, it could be too late for your technician to catch any major problems.


That’s why we recommend you schedule an appointment with an HVAC professional once a year. During this appointment, they will check all of your systems for leaks, wear and tear, and other issues that could lead to more serious problems later on. This way, if there are any issues with your system—like an air filter that needs replacing—they can be taken care of before they become bigger problems.


We recommend replacing your HVAC filters every 3 months. This is especially important in the spring and summer when pollen and other allergens are prevalent.


It’s time for an AC replacement when the following happens:


1. You notice that the air coming out of your vents feels hot. This is a sign that your air conditioner’s compressor has failed and needs to be replaced. The compressor is the part in your AC system that moves heat from inside your home to outside, so if it stops working, you won’t be able to keep cool.


2. Your home feels warm even though it’s set to a low temperature. If you find yourself cranking up the thermostat and still feeling hot in your house, this could be a sign that something’s wrong with your AC unit—or it could just mean that there are some leaks or gaps around windows or doors.


3. You hear strange noises coming from your AC unit while it’s running. If you hear rattling sounds or squeaks from somewhere in your home when the air conditioner is running, this could indicate that something needs repair or replacement before it becomes a bigger problem down the road (like a leaky pipe).


Your air conditioning system might be freezing up because it’s too cold outside.


If you find that your air conditioning system is freezing up, try adjusting the temperature in your home or turning off the AC for a while and allowing it to thaw out. If that doesn’t work, contact a professional.


We get it. It’s annoying, right? But don’t worry! Here are some of the most common reasons your toilet is always running:

  1. Your flapper is broken or not working properly
  2. Too much water pressure in your home
  3. The water level in the tank is too high or low
  4. You have a partially clogged drain

It’s possible that your shower pressure is low because of one of the following reasons:

  • You’re using a water-saving showerhead, which has lower pressure than regular showerheads.
  • Your water pressure is low in general.
  • The hot water heater or pipes are old and have lost some of their pressure over time.
  • You’re running a bath or sink while taking a shower, which will lower the water pressure even more.

Bathroom plumbing systems are surprisingly complex, and they can break down at any moment. That’s why it’s important to keep an eye on your bathroom plumbing—and schedule regular maintenance appointments if needed.


If you’re not sure whether or not you need maintenance, here are some signs that may indicate a problem:

  • Your sink or toilet is slow to drain
  • You hear gurgling noises in the pipes
  • There’s a bad smell coming from the drains
  • You’ve noticed water spots on the walls or ceiling
