HVAC Repairs

Any piece of equipment needs repair from time to time. Heating and cooling systems are no different.

There are several signs that your HVAC has a problem that needs to be addressed:

  • Weak Air Flow
  • Foul Smells
  • Weird Noises
  • Leaks
  • Cold or Hot Spots
  • Cycling On and Off
  • Rising Energy Costs

The quicker a problem is addressed, the better. HVAC issues that are left unchecked will not go away. They generally become bigger, more expensive problems. Repairs also keep your system operating optimally, which can translate into lower utility bills.

Our HVAC pros can also come out annually to check your system. Heating and cooling systems benefit from a regular maintenance program. The system will run better and last longer. Problems can be caught before they become costly headaches.

A Weis Comfort Systems maintenance program includes the following:

  • Check Thermostat Settings
  • Lubricate Moving Parts
  • Tighten Electrical/Gas Connections
  • Clean Components
  • Check Refrigerant Level

Fall is a great time to schedule maintenance service – after the heat of summer but before the deep cold of winter. Your system won’t be working too hard, which makes it an ideal time to tune up the equipment.

Call on our team to maintain your furnace, heat pump, boiler, dual fuel, or geothermal system.

Breathe Easier with Air Purification

Have you ever wondered what is in the air you breathe? You might not see anything harmful, but the air can still contain particulates, VOCs, bacteria, allergens, and other substances that can affect how you feel in the short term and over time.

The Environmental Protection Agency estimates that most Americans spend an average of 90% of their time indoors, making clean indoor air even more important. Coughing, sneezing, headaches, dizzy spells, and other symptoms may not be caused by something you picked up at work or while running errands. The very air in our homes can contribute to illnesses and allergies.

Weis Comfort Systems offers options to improve your home’s indoor air quality:

Installing a carbon monoxide detector can protect your family from serious harm, even death. In low concentrations, this colorless and odorless gas can cause nausea, confusion, weakness, and chest pain. At higher concentrations, carbon monoxide is deadly. Call our team to install a carbon monoxide detection system in your home.
