"After recovering from a horrendous experience with Service Champions (NEVER EVER call them), I got several other quotes to completely replace my old AC system. Brandon and HD had the most competitive quote, great reviews and were very personable and professional. They installed entire new system and did a great job in a timely manner. I highly recommend!"

"I had 4 estimates.  The first vendor said he would be unable to test for leaks and said he would install new system and gave us a one line estimate.

 The second vendor said he could fill with freeon for $800 with no warranty or put in new system for $15k with no itemization,  He only attached a pressure gauge to outside line and was going to charge my very elderly Mom $105.  When I called owner and said that no diagnosis was made and this is ludicrous, he dropped the charge.

 The third vendor spent well over an hour explaining why his company is great and then said the charge would be approximately $9,500.

the fourth vendor was Mick Sinclair and what a completely different experience. I first called and spoke to Nick, his son.  I told him I did not know what to do.  Although both Nick and his Dad were booked solid he said he would get back to me.  Mick called and scheduled an appointment. He measured the pressure and tried to fix the valve. He then actually removed the outer shell of the condensor and noted that the motor was not working at all.  He tried to fix the motor and added a booster to no avail.  He refused to charge anything for the diagnostic and attempted repair - nothing!

Note, that not one of the other three vendors checked the motor.

Mick then said he would email a quote which he did in a very timely manner. His wife sent the email and I spoke to her and she was as nice as Mick and their son, Nick.

Mick spent 1-1/2 days performing the complete installation, including sealing asbestos and many other things.

There are literally no words to explain the excellent service we received from Mick. He is also very kind.

My 92 year old Mom and I are grateful for you.  You are truly a professional.

Thank you!

"During a heat wave we came home after being away for several days to an unresponsive AC unit. We called California Comfort first thing in the morning. Chris already had several repairs booked but he promised he would come before the day was out. He kept his promise, arrived at 6:30 pm and in 15 minutes had our AC unit up and running. To top it off when he found out we were new to SoCal and Riverside, he spent several minutes visiting and sharing his list of things to enjoy in the area. He was professional, knowledgeable, and friendly. We will definitely hire him again if and when the need arises."

"Robert was absolutely exceptional in every way! I called Southland Heating and Air Conditioning to get an estimate for a new HVAC system (my system is about 15 years old) and Robert not only provided a detailed explanation of the best way to upgrade, but he also spotted a problem with the wiring on my Nest Thermostat. A true professional! Highly recommended all around!! I will definitely be a repeat customer!"

"From start to finish, all the representatives of this company were polite, friendly and professional. Their salesman, Jay Godina, was super nice and my husband and I would consider him a friend forever. It was a pleasure to have him every step of the project. He assured us we could call him any time. The men that did the tear out and installation, Salvadore and Rafael, were exemplary employees. They were prompt, polite, knowledgeable and trustworthy. We have only praise and no complaints whatsoever. They went beyond expectations. Our hats off to this company and their employees. They will have our continued patronage. Sincerely, Sherry & Keith"

Install Boiler questions, answered by experts

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.
