The Key to Finding a Reputable HVAC Contractor

The Key to Finding a Reputable HVAC ContractorThe search for a great HVAC contractor for your home can seem daunting, but it’s pretty simple once you know what to look for. We understand the need for proper heating, cooling, and other needs, which is why we’ve come up with a few simple questions for you to ask:

Do the Contractors Keep Up with Industry Knowledge?

We’re not talking about basic industry knowledge — they all have that. What you need to check on is how well the company keeps up with changes in technology and techniques.

What Does Their BBB Listing Look Like?

The first thing you can check out about a company on the Better Business Bureau website is their rating. This is a great indication of how they conduct business. But, also pay attention to any customer complaints and how those were handled.

Are They Properly Licensed and Bonded?

The industry is full of rules and regulations that must be followed in order for an HVAC company to remain in operation. Proof of proper licensing and bonding is always available upon request to ensure that you’re working with a reputable organization.

What Do Their Referrals Say About Them?

First and foremost, you want to obtain a random sampling by choosing a letter or two from the alphabet and asking to see referrals where the last name match those letters. Then, reach out to these people and ask about their experiences in terms of time completion, quality, and other service details.

Is Their Contract All-Inclusive?

When the time comes to employ an HVAC contractor for any job on your home, you want to make sure that the contract covers a variety of information. You’ll obviously want a company to provide a cost and timeframe for completion, but you also need to know how they’ll handle problems that may arise.

Two-Stage Cooling: The Benefits

Two-Stage Cooling: The BenefitsBecause single-stage cooling is more than you need most of the time, two-stage cooling offers better comfort control and lower operating costs. A one-stage air conditioner has only a single cooling output: 100 percent all the time, as long as the unit is running. This all or nothing approach has several drawbacks:

  • Once the house is cooled to the desired thermostat setting, the single-stage A/C continues to operate at 100 percent output, causing the unit to cycle on and off frequently and inducing noticeable temperature swings above and below the desired thermostat setting.
  • Single-stage cooling consumes more electricity, particularly on days where temperatures are more moderate and 100 percent cooling output isn’t required.
  • Because the single-stage unit cycles on and off very frequently throughout the day, it incurs wear and tear faster and may have shorter expected service life.
  • Shorter “on” cycles don’t allow enough time for humidity extraction at the evaporator coil to reach optimum levels. A more humid indoor environment feels warmer and less comfortable.

A two-stage A/C incorporates a compressor that operates in two outputs: 100 percent and approximately 67 percent. When the thermostat calls for quick cooling of an overly warm house, the compressor runs at 100 percent output. Once the thermostat setting has been reached, the system automatically defaults to the lower 67 percent output mode.

Here are some reasons why two stages are better than one:

  • When the system downshifts to the lower output mode, it runs more continuously and maintains more accurate temperature control. This fine-tunes indoor comfort, typically keeping the temperature within one or two degrees of the desired setting and eliminating extreme swings.
  • Running at 67 percent output, the compressor consumes about one-third less electricity so cooling costs are reduced.
  • Because the system runs more continuously, the humidity extraction function — an important component of the cooling process — works more efficiently.
  • Frequent on/off cycling is reduced so wear and tear on critical A/C components is minimized and extended service life is more likely.

In the northern San Diego region, ask the professionals at Sherlock Heating & Air Conditioning for more about upgrading to two-stage cooling.
