"We feel fortunate to have found Pacific Heating and Cooling, they've been servicing our furnace for years. We always ask for Nathan, he knows our system, he likes our dogs and he is always up front about what if anything we need to keep an eye on and what the cost will be when it does come time to take care of it. We have had other technicians come out, they were fine also but Nathan we just really like. We always feel we can trust the work that has been done."

"Ranger did a great job. The estimators were friendly and thorough, the installers and team we encountered were all respectful and hard working. There was a problem with the electronics in the thermostat from the factory, they worked late and had to bring a new thermostat the next day, but the new one works perfectly. We will hire again for any other HVAC needs. We chose a higher quality AC unit and are glad we went with a quieter model, the unit is so quiet in the backyard."

"Seatown installed ductless heating/AC in our home. They did an amazing job getting the install done in just two days. Tyler and Isaiah were at the house working late on a Friday to get the job done. They were friendly, patient, and took the time to explain the plan and expectations of the job each day. We are very satisfied with the installation and the product. I highly recommend the team from Seatown!"

"Received 4 quotes. Cummings was the least expensive that I used to bargain two others to. They matched but had install dates of 30 days. Cummings had their electricians and HVAC guys here in 8 days. Installation done in 4 hours. All had good customer service & tech skills."

"Great. I wanted to replace my oil furnace with a system that does both heating and cooling. They came by, did measurements, and presented some options. I chose the Mitsubishi mini split system because I have a large house and don't need to heat or cool all of it all the time. They installed in a day. Very easy, very boring, I also had them replace the water heater."

"Aaron Charles was our technician. He quickly diagnosed the condition as a faulty circuit board, called to have a co-worker bring a new one and got the furnace running like new. We were so impressed by how quickly he diagnosed the problem and corrected it. We will certainly use Mercurio's (and, hopefully, Aaron's) services again."

Install Boiler questions, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.
