Denver HVAC Repair

An air conditioning system, or a standalone air conditioner, provides cooling and humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against the system intended to maintain constant indoor air conditions. Outside, fresh air is generally drawn into the system by a vent into the indoor heat exchanger section, creating positive air pressure. The percentage of return air made up of fresh air can usually be manipulated by adjusting the opening of this vent. Typical fresh air intake is about 10%.
As you would expect, air conditioning in Portland isn't as expensive as in most areas of the country, owing simply to the fact that most homes don't require particularly large or state-of-the-art units. While our data suggests the national average for air conditioning installation is about $6,000, in Portland we see numbers between $3,000-$4,000, although we've also seen projects as low as $1,500 and as high as $6,000. Heat pump installation is likely to be closer to the national average, but as mentioned, these devices work to be cool your home in the summer and heat in the winter.
The condenser fan is another important HVAC element that must be maintained. Condenser fans that contain oil ports should be lubricated at least annually. The outside condenser should also be shielded from direct sunlight if possible. Keeping vegetation at least two feet away from outdoor HVAC units will also promote higher performance and potentially lower energy bills due to higher efficiency. The further away vegetation is, the better an HVAC unit will operate. 
As much as half of the energy used in your home goes to heating and cooling. So making smart decisions about your home's heating, ventilating, and air conditioning (HVAC) system can have a big effect on your utility bills — and your comfort. Take these steps to increase the efficiency of your heating and cooling system. For more information, see our Guide to Energy Efficient Heating & Cooling (708KB).

Monday the following week, no phone calls, or follow up.  I call to get an update and am told that they cannot install my system because they don't have time.  I ask what does that mean, one year? One week? Until the end of summer they say.  What does that mean I ask?  They say at the end of September.  I say thank you for wasting 1 month of my time.

Absolutely horrible service dont show or call within there appointment window, half to blow up the o...wners phone after there appointment window to get any answers why. And then it takes another 2 hours for there tech to get there after you were told it would be only an hour. Horrible customer service even though it was a Saturday and they made the appointment. But the tech was very professional. Never recommend them only had to use them cause of insurance See More
Other than mineral deposits, the most common problem is sediment in the water supply. The float inlet valve has a tiny hole that easily clogs. The float is usually made of plastic, and if cracked will fill with water and sink. The valve will be stuck open and the reservoir will overflow. Use caution when scraping deposits off the float. If the deposits cannot be removed, replace the float or it will sink and cause an overflow.
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.

Next, consider the age of your unit. Remember, as we mentioned earlier, that the average life of a furnace is around 15 to 20 years. In some cases, during the installation process, your licensed and trained technician will write down the installation date right on the unit. If not, you can check inside the chamber door for a metal identification plate containing the serial and model numbers. You can then call the customer service line of the manufacturer and ask for the manufacture date of the unit.
5) Adjust your thermostat. If you are away for large stretches of time every day, adjust your thermostat to a higher temperature for the time you are away. This will lessen the amount of time your unit has to work each day, and will lengthen its life cycle. An additional benefit will be a lower utility bill each month. Some newer thermostats allow you to pre-program your thermostat to match your schedule so that your home will still be cool when you arrive. Optimizing your system’s usage will maximize its life in the long term.

When central air conditioning service fails during a heat spell, you may have to wait days for an HVAC repair technician or a ac contractor to show up, and you’ll probably pay at least several hundred for the repair. But if you’re comfortable working around electricity and are willing to spend about $50 on parts, you can probably repair your air conditioning service yourself in about two hours and save about $225 on parts markup and labor.
