When you purchase a state-of-the-art HVAC system from Weis Heating and Cooling, our services include maintenance plans and fair prices on installation.

  • Thermostat Settings Check to ensure that your home's furnace keeps you comfortable during the harshest fall/winter conditions, and saves energy while doing so.
  • Tightening of Electrical Connections and measuring voltage and current on motors. Defective electrical connections can lead to hazardous operation of your air conditioning and heating systems and reduce the life of critical components.
  • Lubrication. Non-maintained parts can cause resistance in motors and increase the amount of electricity you use, resulting in wear-and-tear on your system and higher energy use.
  • Check and Inspect the Condensation Drain in your home's A.C., heating system, and/or heat pump (when in cooling mode). A blocked furnace drain can cause water damage in homes and result in higher indoor humidity levels.
  • Check Controls of the Furnace to ensure proper operation. This includes checking the starting cycle of the furnace to make sure that it starts, works correctly, and shuts off properly.
  • Check All Gas (or oil) Connections. Our HVAC technicians in Oakville include testing the gas pressure, burner combustion, and heat exchanger on your furnace to ensure that all parts of your furnace are operating efficiently.

Signs You Need AC Repair

1. Insufficient cooling - If there comes a time that your unit is blowing warm air, call in our Oakville AC repair experts promptly. It could be because of an air filter that needs changing or an evaporator coil that needs a good cleaning.

2. Strange sounds - By now you should know what your AC sounds like. If you notice anything new or abrupt, call in our air conditioning repair team to take a look at your unit to make sure nothing is loose that could break your system down further.

3. Smells that are off - As cooling air requires a bit of condensation, there can sometimes be mold or mildew growth as a result. There could also be a burning smell coming from your AC and that's a sign you need AC repair.

4. Lack of airflow - If you're getting less airflow, but still some then it's likely a problem with your ductwork. No airflow means there's something wrong with your blower fan or your unit is dead completely.

5. Rising utility bills - If you're noticing that your electrical bill is on the up, consider calling in our Oakville AC repair team. It could be that your unit isn't at 100% and that could be rising your utility bills more than you'd like.
