Called a few different places and they were the only ones that called back. The technician Tony came out and after a little testing said the main control board needed to be replaced. He quoted us a total of $489 which seemed on the high side but it was cold and we were somewhat desperate, so we agreed and paid a parts deposit.

Air conditioning is common in the US, with 88% of new single-family homes constructed in 2011 including air conditioning, ranging from 99% in the South to 62% in the West. In Canada, air conditioning use varies by province. In 2013, 55% of Canadian households reported having an air conditioner, with high use in Manitoba (80%), Ontario (78%), Saskatchewan (67%), and Quebec (54%) and lower use in Prince Edward Island (23%), British Columbia (21%), and Newfoundland and Labrador (9%). In Europe, home air conditioning is generally less common. Southern European countries such as Greece have seen a wide proliferation of home air-conditioning units in recent years. In another southern European country, Malta, it is estimated that around 55% of households have an air conditioner installed. In India AC sales have dropped by 40%[clarification needed] due to higher costs and stricter energy efficiency regulations.
A contactor is a $25 mechanical relay that uses low-voltage power from the thermostat to switch 220-volt high-amperage current to the compressor and condenser fan. AC contactors can wear out and are at the top of the list of common air conditioning service failures. Even if your contactor is working, it pays to replace it every five years or so. Unscrew the old contactor before removing the wires. Then move the wires to the new unit (photo 6).
Replacement of air filters: dirty filters can lower your unit’s efficiency and cause damage. You can perform monthly checks and cleanings yourself. If your AC is in constant use, you’ll need to replace the filters once per month to keep the unit running properly. Filters typically cost $15-$60. Some filters are reusable, and only need regular cleaning.
Change your air filter. Air filters need changed every 30 to 90 days, depending on the type of filter you have. It’s a wise idea to get on a regular schedule – note filter changes on your calendar, and make a note to check them every month during the summer, when your system runs ‘round the clock. Follow these filter change instructions to get the job done.
ISO 16813:2006 is one of the ISO building environment standards. It establishes the general principles of building environment design. It takes into account the need to provide a healthy indoor environment for the occupants as well as the need to protect the environment for future generations and promote collaboration among the various parties involved in building environmental design for sustainability. ISO16813 is applicable to new construction and the retrofit of existing buildings.
If your heating system is not running efficiently, it will not heat your home effectively. A good sign you have an inefficient heater is if you notice some rooms in your house aren’t heating to the temperature you set. Older systems could have difficulty heating your entire household, and you’ll know this if you notice some rooms are warmer than others.
Focus first on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter. Next, look to seal any other ducts that you can access in the heated or cooled part of the house. See our Duct Sealing Fact Sheet (787KB) for more information.
HVAC services is our go to contractor when it comes to our HVAC needs. Back in 2013, we were dealt some unforeseeable home projects, as our HVAC was failing and needed to replace the whole system, e.g. Furnace, Blower, A/C, Condenser, Vents, etc... We reached out to a few HVAC companies (Contra Costa Heating and Air, EP builders, High Performance Heating and Air) so we could compare the bids for the job. We have had some issues with past contractors and after thoroughly screening a few of the above mentioned HVAC contractors, we awarded the bid to HVAC services because of their superior customer service and very reasonable pricing.
Many disconnect blocks contain two cartridge fuses. Check them before you proceed with repairs (Photo 3). A blown fuse is a sign of a failing part inside the condensing unit. So don’t just replace it and think you’ve solved the problem. Instead, replace the parts we show here. Then install new fuses and fire up the unit. If it blows again, call a pro—you’ve got more serious issues.
