Is it normal for my heat pump to deliver warm (not hot) air and operates for long periods of time?2019-08-21T15:51:24+00:00

Yes, this is very normal. The heat pump typically will produce air that is 80°, which is considered warm, and will heat the house evenly. However, 80° may feel cool to your hand because your body temperature is closer to 90°.

What can I do to lower my energy bills?2019-07-26T18:53:20+00:00

There are several different ways to help with cost:

  1. Install a programmable thermostat; this will help reduce the work load of your system while you’re not home.
  2. Replace your incandescent light bulbs to compact fluorescents (CFLs) or LEDs, which are more energy efficient.
  3. Use a ceiling fans, when you can, instead of your air conditioner to cool down
  4. Make sure your windows and doors have good seals, so they are not letting air out.
How often should I service my heating and air conditioning systems?2019-08-21T15:39:52+00:00

It is best to have your systems serviced twice a year (once for the heater and once for the air conditioner) to keep it functioning at maximum efficiency. By servicing the systems it helps fix any small problems before they have a chance to become major issues.

How often should I check my air filters?2019-08-21T15:40:51+00:00

It’s best practice to check your filters monthly. If you are using disposable filters (they typically have a cardboard edge), it’s best to replace them when they are dirty… do not attempt to clean it. For the higher efficiency filters, you can go up to three months before replacing them. Keep in mind, during the high-use seasons, it’s better to check them more often.

What maintenance should I do on my air conditioner?2019-08-21T15:42:13+00:00

There are several different things you can do to maintain your air conditioner:

  1. Change your filters on a regular basis
  2. For ground mounted outdoor systems, keep your unit clear of debris, clutter and plants
  3. Keeps pets, and their urine, away from the unit
  4. Be careful when using a weed eater around the unit

  • The power is switched on
  • The circuit breaker is tripped
  • The filter is dirty

Why should I perform preventive maintenance?2019-08-21T15:46:42+00:00

Your heating and air conditioning systems work extremely hard to perform their functions. With the constant stopping and starting that happens throughout the day, the system can wear down quickly if not properly taken care of. By getting your systems serviced regularly you can maximize its life-cycle, as well as guard against many of the unexpected failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts.

This unit had one minor issue after 10 years which was repaired at a minimal cost. Our next home was contractor built and the Heat pump/ A/C unit he installed had problems.
