"Outstanding. Quality West owner, Rob and his assistant Junior, were professional and did outstanding work installing the Aprilaire Humidifier. They were thorough in testing it and delivering an excellent product. I will have them do all my HVAC work going forward."

"Kieth came out multiple times to address the issues I had. Eventually I had him replace my old Furnace, water heater and AC, in addition he cleaned several drains as well. He explained in detail how the project would be competed as well as a time line. He not only finished sooner than expected but did a phenomenal job, he left the work area cleaner than what I had it. I would highly recommend Plumbing Tree for any home services, Even with current circumstances of money being tight I did get multiple other bids and Plumbing Tree was more than fair!"

"Plumber Clay is AWESOME, as the company name indicates. Clay went above and beyond to explain everything that caused my emergency leak/s, he identified the source of my ongoing plumbing emergencies that the previous plumbers couldn't figure out--AND THAT PREVIOUS OWNER DIDN'T DISCLOSE--nor did 3 inspectors to buying this house. He scheduled repairs to work with my budget constraints to hopefully resolve ALL issues. Clay is experienced and well informed, shared his observations, made sure that he answered all of my questions and concerns, and even got me scheduled for additional Awesome Home Services, as they offer more than just plumbing and heating!!!"

"Aether Mechanical is a great contractor: knowledgeable about HVAC design, competent about installation (and nuances for our home), and responsive at the office. Nicolas, the lead engineer, went out of his way to help us with a noise problem (that his work did not cause) after the boiler installation was complete, and he stayed with it until we all found a solution. Great work!"

"Every step, from the estimate with the super friendly Ryan, to the final walk-thru with the always professional Gemini, was absolutely top notch. They installed a new furnace, A/C, and tankless water heater and we are very happy with the work and final outcome. The whole crew was wonderful!"

"I've had Owen do multiple projects around our home, from ceiling fans, shelving. Cabinets and many more. So when we moved into a house that needed a lot of work we called Owen. He installed a hanging very large kitchen hood, and made sure it was secured not only with the manufacturer recommendation but above and beyond. He also installed our very large heavy Iron Front Door. I highly recommend Owen you won't be disappointed."

"Installed new boiler and replaced all the plumbing in our basement (our house is 127 years old). They did a good job and worked hard to get our boiler replaced when the old one gave up the ghost in the winter. Also did a good job replacing all our plumbing in the basement and crawlspace in 2 working days. Kind of a strange name but don't worry, they are a really good plumbing and heating company and offer a 0% interest loan to pay for the bill."

Install Boiler FAQs, answered by experts

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.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.
