"The technician arrived on time and promptly began diagnosing the air conditioning system. When freon levels were checked, it showed that the levels were showing an over charge of the system. When some of the freon was bled off, the numbers went all over the place. The tech cleaned the air conditioner using our own hose, which was not put back in its proper place after he was through with it. We were then advised that we would have to "wait and see" if their repairs would have any effect on the ability of the air conditioner to keep the inside temperature below 79. The tech left and advised they would be back later in the day, or the next day. We paid the bill for the service call and the cleaning of the air conditioner, even though our hose was used. That was $152. After several hours, it became evident that the repairs were having no effect. We waited until 5pm for a phone call regarding a follow-up. At that point we called Purcell, and were told that a tech would be out to follow up. When he arrived, he looked at the system again and couldn't uncover any new issues. We then asked for a quote for a new air conditioner/furnace. At this point, the techs savvy car salesman like skills were quite evident. In addition, they don't participate in the current Ameren Act-on-energy rebates, which would add up to $800. To make up for this, the tech offered a $100 off his total price for the estimates, which ranged from $3400 to $17000. Over the next few days, we had 4 different companies come out to give us estimates on new air conditioners. One company wanted to inspect the current air conditioner we had, to ensure that nothing could be done to the current unit. Upon inspection, it was found that the compressor of the air conditioner was not functioning, which would not allow any tech to get accurate freon readings. This explains why Purcell was receiving errant readings. My question to Purcell is this: What exactly did we pay 152 for? The tech should have recognized that a part as big as a compressor was not running, but he missed it. So long story short, we paid $152 to Purcell for them to mis-diagnose an air conditioner and for them to use our hoses to spray water at the air conditioner unit, and then not put the equipment away. We chose this company due to their good ratings on angies list, but I feel this review should serve as a red flag to any of you who are considering Purcell."

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

The average cost to install a new water heater is approximately $1,300, with a typical price range between $880 and $1,800. The final cost depends on several factors, including the type and size of the unit, its location and accessibility, and the amount of labor required. For example, installing a unit in a tight space like a crawl space can increase labor costs. The type of water heater significantly impacts the price: while a conventional gas heater might cost less than $1,000, tankless models can cost around $2,600 to install (and up to $3,500), and solar heaters can cost upwards of $3,700. Other factors that can affect the total price include the fuel type, vent system requirements, permits, and whether any additional plumbing work or repairs from previous water heater damage are needed.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.
